As Bird Flu Outbreak Expands in California, Dairy Farms Report It’s Worse Than They Expected

Oct 09, 2024

CNN A third farmworker has tested positive for bird flu in California, according to the state’s health department. If confirmed by the US Centers for Disease Control and Prevention, this would be the 17th human case of H5N1 flu in the US since March, when the virus was first detected in cows.

It comes as farmers and veterinarians in California are warning that the infection seems to be striking herds more severely than it has in other states, leading to higher percentages of sick and dead cows in affected herds.

There are no signs of more serious illness in people. Like the first two human cases in California, this third case involves a farmworker who was in contact with sick dairy cattle. Investigators don’t see any connections between the most recent case and either of the first two, suggesting that this is another instance of animal-to-human transmission, the California Department of Public Health said in a news release. In all three cases, symptoms were mild and involved red, bloodshot eyes, a sign of conjunctivitis.

T.K. Cheung Lecture in Animal Science: "Using science to assess and improve the welfare of dairy cattle"

Dan Weary is a Professor at the University of British Columbia. Dan did his BSc and MSc at McGill and Doctorate at Oxford before co-founding UBC’s Animal Welfare Program where he now co-directs this active research group. His research focuses on understanding the perspectives of animals and applying these insights to develop methods of assessing animal welfare and improving the lives of animals. His work has helped drive changes in practices (including the adoption of higher milk rations for calves and pain management for disbudding) and housing methods (including the adoption of social housing for pre-weaned calves). He also studies cow comfort and lameness, social interactions among cows, and interactions between cows, human handlers and technologies like automated millking systems that are increasingly used on farms. His presentation will outline key questions in cattle welfare, highlight recent UBC research addressing them, and showcase innovative methods for improving the lives of cattle and their caretakers.
