Public health officials confirmed six additional cases of bird flu infection of farmworkers, five in California and one in Oregon, raising the U.S. total to 52 this year. The Oregon infection was the first in the state and was tied to an outbreak of the H5N1 avian flu virus at an egg farm in Clackamas County, southeast of Portland. (No paywall)

President Trump rolled up 63 percent of the vote in rural America, a larger margin than in 2016, on the way to winning a second term in the White House on Tuesday. Farm groups offered to work with him on Wednesday to pass the new farm bill, now 14 months overdue, and to bring high costs under control.

Agriculture officials culled all poultry and hogs on a small backyard farm in central Oregon following an outbreak of bird flu that included the first confirmed infection of the H5N1 virus in swine in the United States. There was no threat to the U.S. meat supply, said the Agriculture Department on Wednesday.

Thirty people have contracted bird flu from exposure to infected animals this year, and more cases are expected, said the Centers for Disease Control on Thursday. At the same briefing, the USDA said it was confident of eradicating the viral disease in dairy herds despite the ever-rising number of outbreaks in California.

Drugmakers sold 24 million pounds of antimicrobials for use in food-bearing animals last year, a slight decline from the previous year and the second-lowest total in a decade, said the Food and Drug Administration on Thursday. Sales have declined sharply since the FDA shut down using the drugs to encourage weight gain in cattle, hogs, chickens, and turkeys.

On the same day the CDC confirmed the third human case of bird flu in California, state officials said Wednesday that they had identified two more possible infections, also farmworkers in the Central Valley. In less than six weeks, California has become the U.S. hot spot for bird flu, with one-third of all the infected dairy herds in the country and all of the human cases since Sept. 6.

A dairy farm worker in California’s Central Valley with mild symptoms tested positive for the bird flu virus — the first case in the state and the 16th in the nation this year — said the California Department of Public Health on Thursday. The worker was being treated with antiviral medication and was staying home to recover.

Nearly 200 United Nations member states, warned of the rising health threat of drug-resistant pathogens, approved a declaration on Thursday to step up their work to preserve the efficacy of disease-fighting medicines, reduce the death toll from antimicrobial resistance (AMR) by 10 percent, and “meaningfully reduce” antimicrobial use in agriculture by 2030.

Drug-resistant pathogens could throttle meat, dairy, and egg production and cause millions of additional human deaths by 2050 if the superbugs are not controlled, said researchers on Thursday. They called for increased funding worldwide to prevent the spread of antimicrobial resistance.

Federal researchers found drug residues in one of every five cattle marketed as “raised without antibiotics” in samples collected last fall, said the Agriculture Department on Wednesday. The findings “underscore the need for more rigorous substantiation of such claims,” it said, in “strongly” encouraging — but not requiring — meat processors to routinely test for residues if they put a “no antibiotics ever” label on their meat.

At the same time that the FDA said a second round of tests showed pasteurization kills the bird flu virus in dairy products, the USDA said it would test beef from culled dairy cows for the H5N1 avian flu virus for the coming year. Nearly $2 million has been paid to dairy farmers since July 1 as compensation for milk production lost to bird flu.
