The Worst Avian Flu Outbreak in US History Has Killed Over 50 Million Birds

According to USDA figures released on Thursday, avian flu has killed 50.54 million birds in the United States this year, making it the country’s deadliest outbreak in history.

The deaths of chickens, turkeys, and other birds are the greatest animal health disaster in the United States to date, surpassing the previous record of 50.5 million birds killed in an avian-flu outbreak in 2015.

Infected birds frequently perish. After a bird tests positive for the disease, entire flocks of up to a million birds are culled to control the spread of the sickness.

Poultry flock losses pushed up egg and turkey meat prices to record highs, exacerbating economic agony for households already dealing with high inflation and making Thursday’s Thanksgiving celebrations more expensive in the United States.

Europe and the United Kingdom are also seeing their worst avian-flu outbreaks, with several British supermarkets restricting consumers’ egg purchases after the pandemic interrupted supplies.

The outbreak in the U.S. started in February and spread to flocks of poultry and other birds in 46 states, according to data from the USDA. The virus, called highly pathogenic avian influenza (HPAI), is spread by wild birds like ducks through their poop, and feathers, or by coming into direct contact with poultry.

“Wild birds continue to spread HPAI across the country as they migrate,” said Rosemary Sifford, the USDA’s chief veterinary officer. “To protect U.S. poultry, it is very important to keep domestic flocks from coming into contact with wild birds.”

Farmers had a hard time keeping the disease and wild birds out of their barns, even though they had made their buildings safer and cleaned them up after the 2015 outbreak. In 2015, about 30% of the cases could be linked directly to wild birds. This year, 85% of the cases could be linked to wild birds.

In the hopes of generating fresh guidelines for the prevention of infections, government officials are doing research focusing specifically on diseases that occur on turkey farms. According to the USDA, more than seventy percent of the commercial poultry farms that were affected by the outbreak were turkey farms.

Despite the fact that the outbreak does not pose a significant threat to the general population, the Centers for Disease Control and Prevention in the United States recommend that people avoid coming into unprotected contact with ill or dead birds.
