Alaska's chief veterinarian warns of a mysterious respiratory illness affecting dogs in the Lower 48 and advises local pet owners to take precautions.
Steller sea lions are the most affected by human activities in Alaska, leading to hundreds of deaths, primarily due to entanglement in fishing gear.
An extreme outbreak of salmon lice in Iceland has resulted in an average of 96 lice found on each salmon, causing outrage and protests against Norwegian fish farming companies.
The EPA plans to limit or eliminate a chemical commonly used in car tires, known as 6PPD, after it was found to be fatal to salmon in preliminary Alaska sampling, in response to a petition from Native Tribes and several states, but the rulemaking process is expected to take years.
Toxicological studies spotlight the effects of pollutants on polar bears and whales, with new research strategies being developed to understand their impact on marine life.
A UK study has found that some species of seabirds are developing immunity to avian influenza, which has caused significant mortalities in wild bird populations and poses a threat to human health.
The global surge of highly pathogenic avian influenza H5N1 has led to significant outbreaks and the need for vigilant surveillance and proactive measures to manage and mitigate future outbreaks.
Last month the Finnish Food Authority ordered all minks to be put down at fur farms with diagnosed avian influenza infections. Now the order has been expanded to cover all animals at such farms. The agency’s latest order affects approximately 115,000 animals, including 109,000 foxes.
No one knows how many birds are infected with avian influenza along the coast of Finnmark. In Vadsø, seagulls sit next to dozens of dead birds.
The current outbreaks of avian influenza (also called “bird flu”) have caused devastation in animal populations, including poultry, wild birds, and some mammals, and harmed farmers’ livelihoods and the food trade. Although largely affecting animals, these outbreaks pose ongoing risks to humans.
People spread Covid-19 to wild white-tailed deer more than 100 times in late 2021 and early 2022. The infection circulated widely in the deer population in the United States, and in at least three instances, researchers suspect the virus was passed between deer where it picked up unique genetic changes and then re-infected humans.
Scientists say they found the virus in one of five submitted chicken meat samples that the cats ate.
The highly pathogenic disease circling the globe stands out for its effects on wild birds, and experts say Alaskans should be on the lookout for cases.
When you see a wild bird such as a duck or seagull, think bird flu. Because it’s actually more likely than not they’re infected with the virus. And many species of wild birds are asymptomatic, meaning that they don’t show any symptoms.
State officials say Alaskans who encounter bats should avoid any physical contact. The state's last rabid bat was found last June near Juneau.
Of the 61 red foxes counted in and around Nome between February and March 2023, nearly one quarter were positive.
With geese and other wild birds returning to the region every day, New Brunswick dog and cat owners should be aware of the risk of avian influenza, says the registrar of the New Brunswick Veterinary Medical Association.
This paper analyzes the evolution of the H3 subtype of avian influenza virus in China from 2009 to 2022, including its spatial and temporal distribution and genetic changes. The findings have implications for pandemic preparedness.
Three cases of H3N8 detected in China since 2022 as WHO says strain doesn’t appear to spread easily between humans. First case resulting in death occurred in China.
Alaska researchers will continue a controversial study this year on a parasite in Yukon River chinook salmon that requires killing hundreds of fish, a move that’s drawn sharp criticism from Canadian experts.
