The Big Number: Lyme disease is now in 100 percent of the U.S., Washington Post, Aug 4, 2018
- If you thought you were safe from Lyme disease because you don’t live in New England, where the tick-borne illness first appeared, think again. Now, 100 percent of the country — all 50 states plus the District — has residents who have tested positive for Lyme, a bacterial infection that can cause a wide variety of symptoms, including joint aches, fatigue, facial palsy and neck stiffness.
Here’s why there are so many coyotes and why they are spreading so fast, Washington Post, May 22, 2018
- Coyotes do not breed like rats, but they could hold their own in a contest. It is an animal that, when threatened, somehow reacts by making more coyotes, becoming stealthier, nearly impossible to find even as their numbers grow.
CDC apologizes for hiding ticks on a poppyseed muffin to warn of Lyme disease threat, USAToday, May 8, 2018
This Scary New Report Shows How Unprepared We Are to Fight Tick- and Mosquito-Borne Diseases, MotherJones.com, May 4, 2018
The federal government has stepped up its efforts in the last few years. In 2016, Congress authorized the CDC to use an additional $350 million to fight the mosquito-borne Zika virus—the agency used some of that money the following year to launch five new research centers to study vector-borne diseases. Congress also established the Tick-Borne Disease Working Group in 2017. West Nile hospitalizations have cost nearly $800 million since 1999.
No one really knows exactly how much vector-borne illnesses cost the nation, because so many cases go unreported. But CDC spokesman Benjamin Haynes told me the annual estimated cost for Lyme tests alone is about $492 million. Since 1999, he added, the costs associated with hospitalizing people sickened by West Nile are estimated at $778 million. Yet in 2018, the budget for CDC’s Division of Vector-Borne Diseases is less than $50 million, with $10.6 million of that dedicated to Lyme disease.
Diseases spread by ticks, mosquitoes and fleas more than tripled in the U.S. since 2004, Washington Post, May 1, 2018
But other factors also play a role. The number of Lyme disease cases has increased rapidly because the population of deer — and deer ticks — has skyrocketed. “In New England 100 years ago, there were hardly any trees because they were all cut down for farmland, and the deer had been hunted to extinction,” he said. “All those forests have grown back, the deer population exploded, and the tick populations have also exploded, bringing more disease.”

This Technology Could Stop the World’s Deadliest Animal, Mother Jones News, Aug 14, 2017
- Scientists had been putting the CRISPR tools into their target cells as separate pieces. What if you introduced them into the embryos as a single, heritable element? Those creatures and their descendants—all of them—would retain the gene-editing ability in their DNA. The system would be self-propagating. In short, you could rig nature’s game so your gene would win every time!
But one could build, for instance, a drive targeting Aedes mosquitoes that leaves their offspring unable to reproduce, or one that makes Anopheles mosquitoes unable to transmit malaria. You could design a drive to control a stubborn crop pest or to render white-footed mice incapable of acting as a vessel by which ticks pick up and spread Lyme disease.
- If you’re worried about ticks this year—and if you live in the Northeast, Mid-Atlantic, or Midwest, you probably should be—these five strategies are crucial: Do daily tick checks, Treat your clothes, Spray your skin before going into the woods, Treat your pets, Give ticks no refuge. Another good move: Rid your property of Japanese barberry, an invasive plant that provides ticks with a “buffered microclimate” that keeps them from desiccating and dying.
- Lyme Disease: Inside America’s Mysterious Epidemic, Rolling Stone, June 20, 2017
Finally, in 1981, a scientist named Willy Burgdorfer discovered that Lyme was caused by bacteria carried in mice and deer and transmitted by deer ticks. The spirochete bacteria in question, borrelia burgdorferi, was named in his honor. Once it was established that Lyme disease was a bacterial infection, the course of treatment seemed obvious: antibiotics. Doctors began treating patients with a six- or 12-week dose. Some people got better, but not all of them. Cut to 36 years later, and not much has changed.
- First Report of Dwarf Deer Tick Comes as Overall Population Soars, Global Lyme Alliance, June 8, 2017
In addition to the increasing number of ticks, a greater percentage is infected with the Lyme disease pathogen. “Historically, based on our studies, the infection rate has been in the range of 27 to 32 percent, but this year so far, we have recorded up to 38 percent of ticks infected, and in some regions the infection rate reaches up to 50 percent.Scientists at the Connecticut Agricultural Experiment Station (CAES) have discovered an adult female deer tick that could even more easily escape notice, because it is half the normal size. The miniature tick was just 1.5 millimeters long, compared to the typical 3-millimeter length of an adult female deer tick. As a nymph, it may have been tinier yet.
- See a deer eating a human for the first time in recorded history, International Business Times, May 10, 2017
A human corpse was left on a 26-acre woodland site, known as a “body farm”, as part of a study to see how human bodies decompose in the wild – including the way animals interact with them. Other animals are often seen snacking on decomposing bodies but this is the first time that a deer has been seen helping itself.

- A Natural Cure for Lyme Disease, New York Times, Aug 20, 2016
It’s worrisome that in recent decades, Lyme cases have surged, nearly quadrupling in Michigan and increasing more than tenfold in Virginia. It’s now the “single greatest vector-borne disease in the United States,” Danielle Buttke, an epidemiologist with the National Park Service in Fort Collins, Colo., told me, and it’s “expanding on a really epic scale.”If humans have inadvertently increased the chances of contracting Lyme disease, the good news is that there’s a potential fix: allow large predators, particularly wolves and cougars, to return. They would help keep down the number of deer, which, although they don’t carry the Lyme-causing bacterium, probably encourage its transmission.
- Is a Cure For Lyme Disease On the Horizon?, Town and Country, July 8, 2016
The tests sanctioned by the Centers for Disease Control—ELISA and Western Blot—look only for anti-bodies and are notorious for giving both false positives and false negatives. “We’re looking for the bug in blood, and that has been the holy grail of Lyme disease research,” says Paul Fiedler, a pathologist with the Western Connecticut Medical Group and the director of the group’s Lyme registry, which collects blood from patients with the goal of isolating either the organism or its DNA.
“It’s a very complicated and confusing disease,” says artist Ally Hilfiger, daughter of designer Tommy Hilfiger. “A lot of people get bitten by a tick, get a positive test result, go on antibiotics, and—bam— are better in 30 days. For those who don’t, it’s completely crippling and it steals your life.” At age 18, Hilfiger crash-landed at Silver Hill, in the middle of a mental breakdown, and soon was diagnosed with Lyme. At seven she was bitten by a tick, and then 11 years of clinical limbo, because of repeated false negative test results, clouded what should have been an idyllic childhood in Greenwich, with pain, fatigue, and illness.
On the human level, the situation calls for both common sense and desperate measures. More and more communities are culling their deer populations; on Monhegan Island, Maine, this approach virtually eradicated the disease.

These microbes may include herpes simplex virus 1 (HSV-1), the ubiquitous virus that causes cold sores as well as Chlamydophila pneumoniae and Borrelia burgdorferi, the bacteria that cause pneumonia and Lyme disease, respectively.
- Lyme disease–carrying ticks are now in half of all U.S. counties, Science, Jan 18, 2016
The ticks that transmit Lyme disease, a debilitating flulike illness caused by Borrelia bacteria, are spreading rapidly across the United States. A new study shows just how rapidly. Over the past 20 years, the two species known to spread the disease to humans have together advanced into half of all the counties in the United States.

- How Urbanites Misunderstand Wildlife, New York Times, Jan 13, 2016
The urbanites do understand the need to manage burgeoning animal populations in some areas, but they’d rather use nonlethal means than hunting or culling. With more individuals starting their relationships with wildlife by imbuing it with sentimentality, and the number of hunters on the decline, the consequences will be a result of conflicts over how to deal with invasive species and wildlife population control.

The HSUS representatives, after surveying the land and deer patterns [in Ann Arbor], claim that they can effectively sterilize around 65% of the doe population and in the very best of circumstances 85%. When you are talking about hundreds of deer this is, even in the ideal scenario, far below the 95% needed in an urban area as determined by the Cornell study. Yet, the representatives said that this low percentage should be enough to impact the population. You know, because they said so… that’s good enough right?

Giving the does birth control would be costly and ineffective, he said, and one would have to kill between 40 and 50 deer a year to have an impact that way. Trapping and moving them would just transfer the problem to another community, as the deer have become acclimated to city life, he said.

- The Truth About Chronic Lyme Disease, Yahoo News, Aug 15, 2015
The often-debilitating disease begins with a bite from a blacklegged tick infected, in North America, with the bacterium Borrelia burgdorferi. “Most humans are infected through the bites of immature ticks called nymphs,” according to the CDC. “Nymphs are tiny (less than 2mm) and difficult to see.” This is what Rambo suspects bit her in her garden, though it typically takes upward of 36 hours for the immature tick to transmit the bacterium — not the few seconds it took her to brush the insect away with her gardening glove.

- The Lyme disease debate: Can the condition be chronic?, Fox News, May 6, 2015
Q: What is it that’s creating the epidemic?
A: It’s because of the deer, but also the white-footed mouse, chipmunks, raccoons, foxes, moles, voles, the ticks are now even on birds. The reason it’s a worldwide epidemic is the ticks get on birds and they go to Canada, they go to China. When I was in China and I was speaking with their CDC … they told me privately 6 percent of the Chinese population had been diagnosed with Lyme.
You need to do prevention because one of the viruses we’re now finding, the Powassan virus can get into your body within 15 minutes of a tick bite, and the mortality rates are 10 to 15 percent — up to 30 percent in some studies. So you could get multiple viruses … relapsing fever bacteria, a malarial organism like babesia, with one tick bite. It overwhelms the immune system and that’s one of the reasons people don’t get better.
- Barberry, Bambi and bugs: The link between Japanese barberry and Lyme disease, Scientific America Blog, March 30, 2011
The prevalence of ticks infected with the Lyme disease–causing spirochete (Borrelia burgdorferi) is greater in areas with Japanese barberry than areas without. “Deer eat everything but barberry, and because they don’t eat barberry, they’re weeding out forests. They’re helping promote the invasive species,” explains Jeff Ward, chief scientist for the Department of Forestry and Horticulture at the Connecticut Agricultural Experiment Station (CAES).
Japanese barberry has denser foliage than most native species. As a result, the plants retain higher humidity levels. Ticks need humidity and become desiccated when levels drop below 80 percent. Relative humidity under a barberry is about 100 percent at night.
- Montgomery County looks at bowhunting to cull deer, Washington Post, July 29, 2015
The county’s deer management program has expanded to keep pace, and officials recently proposed a pilot archery hunting program aimed at culling deer herds in Germantown and Potomac.The proposed bowhunting program would allow no more than six hunters in a park at a time, and all hunters will be chosen based on their experience, a background check, safety and ethics training, and their expertise with a bow and arrow.“One of our responsibilities is to manage the parks for biodiversity, and when deer over-browse, it threatens the future of certain plant species and the habitat that is necessary for our wildlife . . . such as nesting niches for birds and rodents and other wildlife,” he said.
Since the county’s deer management program began 19 years ago, hunters have killed nearly 15,000 deer and donated about 750,000 servings of venison to area shelters and food pantries, county officials said.
- Geographic Distribution and Expansion of Human Lyme Disease, United States, Emerging Infectious Diseases, August 2015
Risk for encounters with infected ticks, even within high-incidence counties, is influenced by human behavior and varying landscape characteristics that impact tick abundance and small mammal species composition. Geographic expansion of high-risk areas may occur because of changes in conditions that favor tick survival or because of geographic dispersal of infected ticks by birds and deer to areas where other necessary components already exist to support ongoing transmission. Our results show that geographic expansion of high-risk areas is ongoing, emphasizing the need to identify broadly implementable and effective public health interventions to prevent human Lyme disease.
- Michigan confirms 1st case of chronic wasting in wild deer, Washington Times, May 26, 2015
Wildlife officials stressed there is neither a food safety nor a public health issue and lack evidence of transmission to humans, but global health experts generally recommend that infected animals not be eaten by humans or domestic animals.
Officials said the state has tested about 34,000 wild deer since 1998 and found no evidence of the disease. About 21,000 samples from privately owned deer populations have been tested for the disease and all were negative in the state except for the western Michigan case.
Wildlife officers noted that it’s likely the infected deer lived its entire life in Ingham County, since does in suburban areas tend to have a limited home range. Still, they can’t be sure this is the only case.
- Grass plants can transport infectious prions, Science Daily, May 15 2015
“There is no proof of transmission from wild animals and plants to humans,” said lead author Claudio Soto, Ph.D., professor of neurology at UTHealth Medical School and director of the UTHealth George and Cynthia W. Mitchell Center for Alzheimer’s Disease and Other Brain Related Illnesses. “But it’s a possibility that needs to be explored and people need to be aware of it. Prions have a long incubation period.”
Soto’s team analyzed the retention of infectious prion protein and infectivity in wheat grass roots and leaves incubated with prion-contaminated brain material and discovered that even highly diluted amounts can bind to the roots and leaves. When the wheat grass was consumed by hamsters, the animals were infected with the disease. The team also learned that infectious prion proteins could be detected in plants exposed to urine and feces from prion-infected hamsters and deer.

- If You Care About the Environment and Feeding the Hungry, Shoot Some Deer, Takeapart, March 11, 2015
- White-tailed deer overpopulation has been referred to as a problem larger than climate change. The deer prefer the young shoots and leaves of baby trees, which limits the natural regeneration of forests as older trees die. The only plants that do survive are the ones the deer don’t like, like the hay-scented fern, which, though it only covered 3 percent of forestland in 1900, now covers nearly a third. The deer outcompete any other animal that likes the same plants it likes, including, for example, several kinds of caterpillars. So the caterpillars die, and in turn the animals that eat the caterpillars, like birds, also die. The deer used to have natural predators in wolves and mountain lions, but those were extirpated before the deer’s comeback in the mid-20th century, leaving nothing to keep the population in check.
- Exhibit at Smithsonian Natural History Museum
While many native species are in trouble, white-tailed deer are thriving. Many people think of them as woodland animals, but they can live in prairies, and near farmlands and suburban backyards. Where populations are high because there are no natural predators, browsing deer can change the composition of plant and animal communities.
- Deer Hunting in D.C. Park Upheld on Appeal, Courthouse News Service, Jan 26, 2015
WASHINGTON (CN) – Protecting the native ecology of Rock Creek Park justified the mass killing of deer there, the D.C. Circuit ruled, upholding the first authorized killing of animals in that park’s 120-year history.
Rock Creek, a 1,750-acre national park in north Washington, has been overcrowded with white-tailed deer since the early 1990s.
A deer-management plan that the service published in 2009 recommended a combination of lethal and non-lethal population-control methods to bring the deer population down to 15 to 20 per square mile.
In Defense of Animals and five individuals who objected to the plan filed suit after its adoption in May 2012. In ruling against the activists as well last week, the D.C. Circuit rejected their claims that the Park Service failed to meet the threshold for taking action.

Moreover, at least four pathogens, in addition to the Lyme bacterium, can be transmitted by the black-legged tick: Anaplasma phagocytophilum, which causes anaplasmosis; Babesia microti, which causes babesiosis; Borrelia miyamotoi, a recently discovered genetic relative of the Lyme spirochete; and Powassan virus. Some of these infections are more dangerous than Lyme, and more than one can infect a person at the same time. Simultaneous infection, scientists suggest, may well enhance the strength of the assault on the immune system, while making the disease itself harder to treat or recognize.

- Venison As Benison: Food Banks Score From Deer Overpopulation, NPR, Dec 9, 2014
White tailed deer are so common in Washington, D.C., that my kids barely take note, even if I have to slam on the brakes to avoid hitting them. But the National Park Service says there’s a problem beyond the risk of driver-deer collisions, which lead to an estimated $4 billion in damages each year. The overabundance of deer are a threat to native vegetation.
Around the country, there are lot of examples of deer meat being salvaged and donated to food banks. In Pennsylvania, a group called Hunters Sharing The Harvest helps hunters distribute their extra venison, using a state-wide network of butchers who help coordinate deliveries to local food banks.
According to Jenny Anzelmo-Sarles, spokesperson for the National Park Service’s National Capital Region, government agencies have been linking their deer reduction efforts to food banks seeking protein for years. Not only do they provide the meat, but the agencies also usually pay to have the meat ground and cut by local processors.
Hunters in many states are doing the same thing. In New York State, the Venison Donation Program is a partnership between hunters and the Food Bank of the Southern Tier, which received 6,274 pound of venison in 2013. The donations are made at no cost to hunters.
And, in Indianapolis, according to a report from WISHTV.com, 4,800 pounds of deer meat is expected to be donated to the Gleaner’s Food Bank this year. Some of the meat was donated from a private deer hunt in Eagle Creek Park.
Gleaner’s Food Bank welcomed the donation, noting that venison doesn’t come cheap. If you’re paying retail for this meat, you’re looking at upwards of $9 a pound.

AKRON, Ohio (AP) – Sharpshooters would kill as many as 350 deer annually for four years under a plan to reduce herd size in the Cuyahoga Valley National Park, under a plan announced this week. The goal of the plan unveiled Thursday is reaching sustainable numbers of 15-30 deer per square mile in the park between Cleveland and Akron, down from the current 41 per square mile.
- In the Crosshairs: What happens when a national park has too many deer?, National Parks Conservation Association, Fall 2014
Allowing deer to destroy the habitat for all the other animals in the parks is unacceptable, say national park managers. Over-browsing also leads to severe erosion, particularly now that climate change is causing more intense storms. “Given all the damage done over the decades, it’s hard to know when things will come back,” says Valley Forge’s Gibson. “We can’t step back to how things were before deer made the land so bare. Today, the climate is much hotter, rain is more acidified, and rainstorms are more hurricane-like, which intensifies erosion. We’re in a brave new world as far as forest regeneration.”

The 13-year study, which ran from 1995 through 2008 in Mumford Cove and Groton Long Point, used hunters to reduce deer densities from a peak of 80 deer per square mile to about 13 per square mile. That decline in deer numbers slashed tick abundance by 76 percent, which resulted in 80 percent fewer cases of Lyme disease reported by the towns’ residents, who were surveyed at least six times during the study.
- Trying to limit the number of deer, with surprising results, WashingtonPost, Sept 29, 2014
Cornell’s administrators chose to experiment with sterilizing many of the wild deer on campus — and the result was something that nobody anticipated. Cornell chose tubal ligation, which unlike chemical forms of birth control, is typically permanent and avoids the expense of capturing the same deer each year to maintain their infertility. At a cost of roughly $1,200 per deer, 77 does were captured and sterilized though tubal ligation. (Without the help of the Cornell University College of Veterinary Medicine, the costs would have been higher.) However, because the ligated does were unable to become pregnant, they continued to produce chemical signals of readiness to reproduce — signals that can attract bucks from miles away– so the number of deer on campus did not decrease, just many more males than normal.

the study included nearly all the permanent residents of a Connecticut community who reported their cases of Lyme disease between 1995 and 2008. The researchers found that a hunting program to reduce the number of deer in the area led to a significant reduction in the number of cases of Lyme disease. Reducing deer density by 87 percent — to 5.1 deer per square kilometer (four-tenths of a square mile) — resulted in a 76 percent reduction in the tick population, according to the study, published recently in the Journal of Medical Entomology.

We reported several months ago that the Humane Society of the United States’ education arm—Humane Society University—is dead. The whole program seemed like a scam from the get-go: HSUS tried to get accreditation from the Middle States Commission on Higher Education, which would have allowed HSUS to get federal (i.e. taxpayer-funded) grants. Getting federal grants isn’t a big deal if you’re the University of Virginia, but when you’re the educational arm of a radical animal liberation group with a PETA-like agenda, the taxpayers shouldn’t have to subsidize your propaganda. Fortunately, it seems Humane Society “University” couldn’t get accreditation.

Hastings-on-Hudson Mayor Peter Swiderski said that out of 120 deer, only eight doe were tranquilized, tagged and injected with birth control over the monthlong program in March, seven in the final week alone. That was far short of the goal of injecting 40 to 50 does in the first two years.

In what could be seen as a softening of tactics, Unified Sportsmen’s president is now proposing ideas that would help the Game Commission to trim deer populations in urban areas. Santucci said he understands the irony.“This is something from outside the box,” he said, “to help address the economic impact of hunters no longer going to camps in the mountains where there used to be lots of deer, and problems in the suburbs where they have the opposite problem of too many deer.”

To reduce those numbers, Hastings is trying to keep its female deer from getting pregnant by injecting them with a contraceptive vaccine. That has researchers from the Humane Society of the United States cruising the village’s streets.
The Teatown Lake Reservation in Yorktown recently enlisted specially trained biologists to shoot 11 deer. Some Westchester County parks and the Mianus River Gorge Preserve have used bow hunters to reduce their deer numbers.
Researchers hope to treat 60 deer this year and during the next two winters, and to continue to monitor them. Captured does — tranquilized first with a drug-filled dart — will have a numbered ear tag attached, blood drawn for a pregnancy test and an initial vaccine dose. Known as PZP, the vaccine uses a doe’s immune system to stop her eggs from being fertilized.
But after about a week of looking for deer, Naugle and Grams had tagged and treated just one. They can fire at deer no more than 20 yards away with their air-powered rifles, and they are still learning where the animals spend their days.

While some communities have used lethal means to curb the exploding population of deer, which roam backyards, destroy gardens and wander into traffic, others have taken what they see as a more humane approach — tranquilizing female deer and removing their ovaries.It’s expensive: The town of Cayuga Heights, N.Y., spent $35,808 to sterilize a dozen does last month. A year earlier, the town spent $148,315 to remove ovaries from 137 female deer. And after the 2012 effort, a survey found an estimated 225 deer — or 125 per square mile — were living in the village, well above the recommended population for suburban communities of 15 to 20 deer per square mile.“In most cases, they are not effective and incredibly expensive,” Kip Adams, director of education and outreach at The Quality Deer Management Association, told FoxNews.com of sterilization efforts. “There’s a lot of costs involved and at the same time, there’s a lot of stress placed on the animals. And at the end of the day, in most cases you still have well over 100 deer per mile, which is at least five times higher than the recommended amount.”

The first step is for state wildlife agencies to stop increasing the population of certain species, especially deer. These agencies are currently funded fully or partially by the sales of hunting and fishing licenses and their mission statements include hunting, both explicitly and under the guise of “recreation,” “use” or “benefit” of the citizens.

- U.S. Lyme Disease Cases Vastly Underreported: CDC, US News & World Report, Aug 19, 2013
About 300,000 Americans are diagnosed with Lyme disease each year, which is about 10 times higher than the number of cases reported each year to the U.S. Centers for Disease Control and Prevention, according to a new report.
- The Lyme Wars, The New Yorker, July 1, 2013
Lyme disease is the most commonly reported tick-borne illness in the United States, and the incidence is growing rapidly. In 2009, the C.D.C. reported thirty-eight thousand cases, three times more than in 1991. Most researchers agree that the true number of infections is five to ten times higher. Although some of that increase is due to heightened awareness, transmission is rising in areas, like New England, where the disease is well established, and is spreading to regions as far south as Florida, through changes in climate and the movements of infected animals.

Until mountain lions and timber wolves return to the District, Rock Creek Park’s swollen deer herd
will have to depend on humans to control its numbers. Although deer culling in the park is currently done only with lethal methods, the Park Service continues to examine birth-control options. A birth-contol agent, however, must meet several criteria. It must . . .
♦ be federally approved,
♦ prove successful for 3 to 5 years,
♦ be administered by dart,
♦ leave no residue in the meat,
♦ have little or no behavioral impact on the deer.
“No agent exists at present that fully meets all criteria,” said Nick Bartolomeo, the park’s chief of resources management.

“The Science of Overabundance,” a Smithsonian book published 15 years ago, asserted that even then, many areas clearly had too many whitetails. The book, written by 42 scientists and wildlife biologists,defined overabundance this way: when deer threaten human life or livelihood, when they depress densities of favored species, when they are too numerous for their own good and when they cause ecosystem dysfunction.

Less appreciated, though, is how these millions of deer are quietly eating every palatable leaf within their reach across the eastern forests of North America. That’s very bad news for migratory birds. Migratory warblers generally feed in the treetop canopy, but many treasured species — worm-eating, Kentucky and hooded among them — hide their nests in dense vegetation on or near the ground. Deep in the woods, buffered from suburban predators and rural pesticides, warblers should be able to nest in peace. But they can’t do so when hungry deer have demolished the forest understory.

“‘People think that as we continue to develop, we squeeze wildlife out of the woods. But that’s not true with deer,’ Davis said. ‘They are among certain species of animal that absolutely thrive in suburbia. They do better in suburbia than they do in a similar size area of virgin woods. We’re actually making conditions better as we develop.’”

In a sweeping study of a huge swath of Michigan’s Upper Peninsula, researchers documented that in many places, the sugar maple saplings that should be thriving following harvesting are instead ending up as a deer buffet. This means the hardwood forests are not regenerating.

Unlike human hormone-based contraceptives, which prevent ovaries from releasing an egg, PZP causes a female deer to produce antibodies that stick to the egg’s surface. The antibodies block sperm from fertilizing the egg. The drug has to be given directly into the bloodstream, largely because researchers have yet to develop an oral version that can survive a trip through a deer’s digestive system. The U.S. Food and Drug Administration still considers the drug “experimental.” The manufacturer prohibits women, such as McShea’s female co-workers, from handling the contraceptive—nobody knows if it could sterilize them too.

Md. approves use of deer birth control, Washington Post, May 5, 2011
“This is the only immuno-contraceptive for deer that has federal approval,” said Paul Peditto, director of the Wildlife and Heritage Service. “It was developed by the U.S. Department of Agriculture and is registered with the Environmental Protection Agency.
Peditto said the manpower and expense of applying the birth control chemical will limit its use. “It will cost up to $1,000 to apply it to a deer,” Peditto said. The deer must first be shot via dart gun to tranquilize it before Gonacon can be injected. EPA requires that the deer be tagged so that it can be identified as having been treated. Another tag will state that the meat of the animal should not be consumed by humans.
