US requires bird influenza tests for dairy cattle moving between states

The U.S. government will require dairy livestock moving in between states to be evaluated for bird flu starting on Monday as federal authorities increase their action to a break out that has actually bled over into the U.S. milk supply.

Farming Secretary Tom Vilsack on Wednesday stated all labs and state veterinarians in the nation must report favorable tests, and the U.S. Department of Farming (USDA). would pay for increased screening.

The steps aim to include the spread of bird flu, which. has been reported in eight states and 33 dairy herds considering that it. was first spotted in late March in Texas. An individual exposed to. livestock tested positive for the disease and suffered. conjunctivitis.

Dr. Michael Worobey, an evolutionary biologist at the. University of Arizona, said based upon brand-new info, it appears. that infections with the H5N1 infection in dairy livestock happened. through a single transmission occasion from a bird to a cow. at some point in late 2023, likely in December.

Worobey and colleagues evaluated genetic sequences of the. virus launched by the USDA over the weekend.

The U.S. Food and Drug Administration reported on Tuesday. that it discovered bird influenza infection particles in some pasteurized milk. samples, but stated it remains safe for human consumption as such. milk has actually been heated up to a high temperature to kill harmful. bacteria and viruses.

Vilsack stated the U.S. milk supply is safe based on the. details we currently have available, including that no live. infection has been discovered.

Milk consisting of bird influenza particles entered the commercial. supply from asymptomatic cows that were discovered to be contaminated. through testing, he said.

USDA has carried out more than 2,000 tests on cattle samples. over the last a number of weeks, Vilsack stated.

Dairy cows need to test negative for influenza A virus, which. consists of bird influenza, at an approved lab before being. delivered throughout state lines, the USDA said. Owners of cows that. test positive will be required to provide epidemiological. info, consisting of animal movement tracing, the department. stated.

The company plans to initially focus testing on lactating. cows.

SPREAD BETWEEN COWS

Richard Webby, director of the World Health Company's. Collaborating Center for Studies on the Ecology of Influenza in. Animals and Birds at St. Jude's Children's Research Hospital in. Memphis, stated screening cows about to be transported will assist.

If we can control the virus moving with those cows, then. definitely we're going to be much better off, Webby said.

Favorable flu tests will prohibit cows from being moved for. 1 month and up until they check negative, Vilsack included. Dairy. cattle appear to recuperate from bird flu, an illness typically lethal. to chickens and turkeys.

Over the last several weeks, USDA has actually kept in mind spread in between. cows within the same herd; spread from cows to poultry; spread. between dairies associated with livestock movements; and cows. without medical signs that have tested positive, Vilsack stated.

USDA estimates it will require about $500 million to continue. to deal with break outs in dairy cows, business poultry flocks,. wild birds and potentially other species.

It is settling a demand to transfer cash from the. Commodity Credit Corporation, which supplies funds from the U.S. Treasury to assist support farming prices and assistance farm. earnings.

The Meat Institute, which represents U.S. meat processors,. prompted USDA and the U.S. Centers for Disease Control and. Avoidance (CDC) to conduct additional screening to ensure beef. remains safe to eat and to secure meatpacking employees from. infection. USDA said it is positive the meat supply is safe.

The CDC maintained its low threat evaluation for the general. public after USDA microbiologists on April 16 determined a. shift in an H5N1 sample from a cow in Kansas that could indicate. that the infection has an adjustment to mammals, the USDA said.

The finding had been seen formerly in other mammals and. does not effect viral transmission, according to the department.

The USDA in a declaration said it has actually not found modifications to. the infection that would make it more transmissible to humans and. between individuals.
