Officials say the "risk remains" across the state for this "highly contagious disease" and offered tips on how to avoid it.

The DEC tested 2,720 harvested deer across the state and found no evidence of CWD in the herd, according to the DEC. DEC partners with cooperating meat processors and taxidermists to obtain samples for testing each year.

"Every year New York remains free of Chronic Wasting Disease is a success, but the risk remains," Department of Environmental Conservation (DEC) Commissioner Basil Seggos said. "Hunters are critical for New York's ongoing monitoring and CWD prevention efforts, as well as continuing to take preventative steps to keep our state's deer herd safe. Hunters who hunt deer or elk out of state may inadvertently-but illegally-bring CWD-infected carcasses or animal parts into New York, a potential disaster for deer and those who love deer. We encourage hunters to continue to support DEC's efforts to keep New York CWD-free."

CWD is a highly contagious disease that affects deer, elk, moose, and caribou. CWD poses a significant threat to New York's wild white-tailed deer herd, according to the DEC. It is always fatal and there are no vaccines or treatments available. CWD is believed to be caused by a prion, which is an infectious protein, that can infect animals through animal-to-animal contact or contaminated environments. CWD has been found in 26 states.

To expand protections for New York deer and moose, DEC adopted regulations in 2019 to prohibit importation of carcasses of deer, elk, moose, and caribou taken anywhere outside of New York. DEC also strongly recommends that hunters not use natural deer urine-based lures, which could contain CWD prions. Hunters that believe lures are important for their success can use synthetic products.

Northern gannets (pictured here at Unst Island in Shetland, Scotland), are large, migratory seabirds known for their high-speed plunge dives. The seabirds can be found on either side of the Northern Atlantic. Scotland is home to Europe's largest population of northern gannets, with Bass Rock serving as home base for the largest colony, with upwards of 150,000 of the 5- to 7-pound birds. In October, gannets head south to the West Coast of Africa and beyond, returning as early as February.

A deer concern in the Scottish Highlands

More than half of the 1.5 million red deer in the United Kingdome live in Scotland, where their population has doubled in the last half-century. The boom to their numbers comes from a total lack of predators, leaving the deer to reproduce with reckless abandon, causing significant upticks in Lyme disease cases, obliterate the ecosystem, and strip tree bark bare. In this photo, red deer graze in Glen Etive, Scotland.

Goats in the trees of Morocco

Goats in Morocco are encouraged by farmers to eat ripened fruits on argan trees (Argania spinosa). This is because the fruit's nuts, used to produce argan oil, are extremely difficult to harvest. The goats eat the fruit, swallow the nuts, and the goats' digestive tracks soften the nuts before they are passed as waste. Farmers can then gather and grind nuts into oil. The goats in this picture are eating argan fruits in Essaouria, Morroco.

It's Not Always the Ones That Roar and Stampede

As it turns out, the world’s deadliest animals may actually be the smallest ones. Which tiny pest tops the list? Read on to find out the world's deadliest animals.

#15. Elephant

Number of people killed in 2015: 100
Percent of total worldwide deaths from animals: 0.01%

The African elephant is the world’s largest land mammal, with the Asian elephant not far behind. These far-ranging animals need plenty of land to forage, but as human populations continue to grow, elephants and humans find themselves in conflict over space. Only about 20% of their habitat is protected, and when people encounter elephants outside those areas, the results can be fatal for both species.

Every year in sub-Saharan Africa, tourists get a close-up look at the king of the jungle in its natural habitat. Perhaps unbeknownst to them, lions see nearly everything around them as potential prey, In the wild, old or sick lions often attack humans, which they see as easier prey. Lions are also more likely to attack during the 10 days after the full moon.

#13. Hippopotamus

Percent of total worldwide deaths from animals: 0.03%

The hippopotamus, Greek for "river horse,” are semi-aquatic mammals of sub-Saharan Africa that spend up to 16 hours of their day submerged in water. They’re not gentle giants, however; male hippos are incredibly territorial, can run up to 20 miles an hour, and attack with 20-inch canines.

#12. Crocodile

Number of people killed in 2015: 1,000
Percent of total worldwide deaths from animals: 0.07%

Though sharks are often pointed to as the most common underwater menace, crocodiles are historically 100 times deadlier. Their bite is three and a half times more powerful than a lion’s, and these opportunistic predators hunt to kill. Saltwater crocodiles are more deadly than their freshwater counterparts, and their attacks tend to be most common between October and March when the water is warmer.

#11. Tapeworm
#11. Tapeworm

#11. Tapeworm

Number of people killed in 2015: 1,600
Percent of total worldwide deaths from animals: 0.1%

Tapeworms can’t digest food on their own, so they live in hosts’ intestines to get the nutrients they need to survive out of food that's already been digested. Chances of infection are higher in parts of the world where free-range livestock are more common, but the condition can be easily treated. Avoid getting one in the first place by ensuring all food is thoroughly cooked in regions that harbor the parasite.

#10. Ascaris roundworm

Number of people killed in 2015: 2,700
Percent of total worldwide deaths from animals: 0.18%

Roundworms, also called hookworms, are parasites typically found in soil. Like tapeworms, they live in the intestines of hosts who eat contaminated foods. The CDC estimates that between 807 million and 1.2 billion people are infected with roundworms worldwide, which accounts for most parasitic diseases. Luckily, most show few symptoms, and the parasites are only considered deadly in parts of the world with inadequate health care facilities.

Percent of total worldwide deaths from animals: 0.23%

Most species of scorpion will only cause minor pain and irritation if they sting you. Cousins to spiders, mites, and ticks, only 50 species have venom powerful enough to be dangerous to humans. Luckily, only one species in the U.S. poses a danger: the bark scorpion found in southern Arizona and western New Mexico.

#8. Tsetse fly

Number of people killed in 2015: 3,500
Percent of total worldwide deaths from animals: 0.23%

Tsetse flies look like common house flies, but these insects are far deadlier. Like mosquitos, they feed on the blood of mammals, transmitting diseases like trypanosomiasis, also known as "African sleeping sickness.” Early symptoms include aches, pains, and itching. As the disease progresses, victims experience confusion and disruption of the sleep cycle. Left untreated, the condition is frequently fatal.

#7. Freshwater snail

#7. Freshwater snail

Number of people killed in 2015: 4,400
Percent of total worldwide deaths from animals: 0.29%

Unlike the snails you might find in your garden, certain freshwater snails carry the second-most devastating parasitic disease on the planet: schistosomiasis. These snails shed the parasites into the water, contaminating it and infecting hosts who come in contact with it. Once inside the host, the parasites lay eggs with sharp barbs that embed into internal tissue. Schistosomiasis is fatal in about 10% of cases.

#6. Kissing bug

Number of people killed in 2015: 8,000
Percent of total worldwide deaths from animals: 0.52%

Kissing bugs might sound sweet, but they’re carriers of the deadly Chagas disease, the American form of trypanosomiasis, or "African sleeping sickness.” The bugs bite hosts on the thin skin near their eyes or mouth ("kissing” them) and leave behind droppings that infect through the wound. They’re mostly found in Latin America, but there have been reported sightings throughout the southern U.S. as well.

#5. Dog

#5. Dog

Number of people killed in 2015: 17,400
Percent of total worldwide deaths from animals: 1.13%

As much we love them, dogs are still descended from wolves and, like wolves, they bite. While dying from a dog bite on its own is incredibly rare, you should make sure your four-legged friend has had its shots regardless. That's because dogs are the lead source of rabies deaths in humans, accounting for 99% of cases. Africa and Asia experience the most dog bite-related deaths, due to large stray dog populations.

#4. Sandfly

#4. Sandfly

Number of people killed in 2015: 24,200
Percent of total worldwide deaths from animals: 1.57%

Sandflies live in Africa, the Mediterranean, the Middle East, Latin America, and Asia—especially India. Their diet consists largely of plants, but females also feed on blood while producing eggs and transmit the Leishmania parasite in the process. Most infected people never get sick, but those who get Leishmaniasis can develop one of the three forms of the disease. The most deadly is visceral Leishmaniasis, which is fatal in 95% of untreated cases.

#3. Snake

#3. Snake

Number of people killed in 2015: 60,000
Percent of total worldwide deaths from animals: 3.9%

Snakes are one of the most commonly feared animals, and rightfully so. The World Health Organization estimates that snakes bite 5.4 million people every year, with 2.7 million of those bites are from poisonous snakes. Snake venom can cause blindness, necrosis, and death. There are usually only five or six snakebite-related fatalities per year in the U.S., while India is believed to have the most with about half of the world’s snake bites each year.

#2. Human

#2. Human

Number of people killed in 2015: 580,000
Percent of total worldwide deaths from animals: 37.73%

As serious as animal attacks and parasitic diseases can be, you’re much more likely to be killed by another human. The Gates Notes study found that homicide accounted for around 409,000 deaths, with war casualties comprising the other 172,000. 2016 marked the first year in more than a decade that the global homicide rate rose, while recent studies have found that wars may have led to three times more deaths in the last 50 years than estimated.

#1. Mosquito

#1. Mosquito

Number of people killed in 2015: 830,000
Percent of total worldwide deaths from animals: 54%

Mosquitoes are capable of transmitting many deadly diseases, including malaria, West Nile virus, Zika, dengue fever, yellow fever, and chikungunya. Distributing bed nets and eliminating the insects’ breeding ground of standing water have been among the proposed solutions to this rampant problem. Nevertheless, it has proven complicated to implement an effective plan. The Gates Foundation has recently pushed for a different solution: using gene-editing technology to eliminate malaria-transmitting mosquitoes altogether.
