California - Avian flu in mammals and livestock 2024

[sharon sanders]

Helen posted this today. I presume it is the 475 from the above report plus the 6 newly listed USDA herds. 475 + 6 = 481. The problem is that I don't know how many of the newly listed USDA 6 (if any) are included in the California 475 from yesterday.

Really the number is a range now because of the overlap in reporting between the state and USDA. For instance, so odd...in post #92 above, the USDA has a herd with the number 028 dated Nov. 21. What? The sequence numerically is now in low 500s. Where has this #028 been since Sept.?

13 more H5N1 something...maybe a typo...one entry is blank where the animal description should be. Also...look at 2 entries...#240 and#254 appearing on a Dec. 3 list....that numbering range is from early November:

Los Angeles public health officials are investigating two possible cases of fatal bird flu found in cats that consumed recalled raw milk from the Fresno-based dairy Raw Farm LLC.

The Los Angeles County Department of Public Health said in a news release Thursday that it is obtaining testing to confirm the suspected bird flu cases.

The indoor cats consumed raw milk, which was linked to the recall of specific products from Raw Farm, before the onset of symptoms, according to the public health department. Those symptoms included a “lack of appetite, fever and neurologic signs.”

The cats died after their illness worsened. They tested positive for Influenza A, according to the public health department.

According to the Centers for Disease Control and Prevention, influenza virus types A and B “cause most human illness and the flu season.” The public health department said the positive tests are a “rare result in cats.”...

County of Los Angeles Public Health
For Immediate Release:

December 12, 2024 Suspected H5 Bird Flu Detected in Los Angeles County Cats That Consumed Recalled Raw Milk


The Los Angeles County Department of Public Health is investigating two possible cases of H5 bird flu in cats that consumed recalled raw milk from Raw Farm, LLC.

The infected indoor cats consumed raw milk linked to a recall of raw milk and cream products prior to the onset of symptoms, which included lack of appetite, fever and neurologic signs. The infected cats died after severe worsening of their illness, and subsequently tested positive for Influenza A, a rare result in cats.

Public Health is considering these suspected H5 bird flu cases and is obtaining confirmatory testing. The nationwide H5 bird flu outbreak has seen other cats infected with the virus after consuming infected raw milk.

People who had direct contact with the cats are monitoring for symptoms and have been offered antiviral prophylaxis. There have been no human cases of bird flu associated with exposure to these cats yet identified. The investigation is ongoing.

More herds added to the Dec. 10 & Dec. 11 list + 5 on Dec. 12. It is not appreciated that the USDA is releasing partial confirmation information on one day and then posting the rest of the confirmations on a different business day. It makes keeping track of developments more fuzzy. Please release all daily confirmations at the same time. There is no reason to post Dec. 10 confirmation over a 3 business day period. Is this on purpose?

Why is herd #CA 337 confirmation posted today? That herd number would indicate a test sample taken sometime in early November. Are there internal delays, re-testing, disorganization? I would expect some intermittent numbering as results are developed but look at the range of herd numbers posted today.....#337....then some 500s...then a few 600s up to #649. Not confidence building.
