          This is California case #41 which was added to our main list yesterday based on California's announcement. Sometimes the USDA makes the 1st notice, sometimes it is the state. Makes for an interesting balancing act. Anyway...California has confirmed 41 cases so far.

            California Dept. of Health
            Current H5N1 Bird Flu Situation



            Updated October 1, 2024

            For up to date information on bird flu detections in livestock or poultry, please see California Department of Food and Agriculture (CDFA)

            Avian Influenza Updates​.
            • To date there have not been any confirmed human infections of bird flu in California, and the current risk to the public remains low.​
            • Individuals with close contact to infected birds or other animals, such as livestock or wildlife, have a greater risk of infection.​​
            • CDPH is working with local, state, and federal partners to monitor bird flu in farm animals and people who work closely with poultry and cattle. Please check back frequently as information will be updated as it becomes available.​​
            What You Need to Know
            • Flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs. Flu can make both people and animals sick.
            • Novel flu means “new flu” and is a type of disease that can spread between animals and humans (called a “zoonosis”).
            • Novel flu is different from seasonal flu in humans. Seasonal flu normally spreads among humans and infects many people every year.
            • Most people do not have any immunity against novel flu, so prevention is important to keep novel flu from spreading.

              October 1, 2024: H5N1 Bird Flu Confirmed in Forty-Four Dairies in California


              SACRAMENTO, CA — Following an investigation by the California Department of Food and Agriculture (CDFA) and rapid disease detection by California Animal Health and Food Safety Laboratory System (CAHFS), the U.S. Department of Agriculture’s (USDA) National Veterinary Services Laboratories (NVSL) has confirmed highly pathogenic avian influenza (HPAI) in forty-four dairies in Central California. CDFA has implemented a surveillance strategy with the goal of finding affected farms as early as possible. Early detection provides the opportunity to work with farms to quickly implement enhanced biosecurity, cow care, and employee protection.

              This nationwide outbreak of HPAI H5N1 began in poultry in 2022 and was first detected in US dairy cattle in March 2024. All national detections in cattle can be found on the USDA website at the following link: HPAI Confirmed Cases in Livestock | Animal and Plant Health Inspection Service (usda.gov). Note that the website is updated at noon Eastern Standard Time.

              All affected dairies have been placed under quarantine. Enhanced biosecurity measures are in place to prevent the spread of the virus. Sick cows are isolated and being treated at the dairies. Most infected livestock and dairy cattle can fully recover from HPAI infection within a few weeks.

              California's supply of milk and dairy foods is safe and has not been impacted by these events. Healthy cows have been cleared to continue shipping milk for pasteurization. Pasteurization of milk is fully effective at inactivating the virus, so there is no cause for concern for consumers of milk or dairy products that have undergone this process. Pasteurized milk and dairy items, as well as properly handled meat and eggs, continue to be safe to consume.

              No human cases of HPAI related to this incident have been confirmed in California. According to the California Department of Public Health (CDPH) and the Centers for Disease Control (CDC), this influenza virus is not considered a significant public health threat, and the risk to humans continue to be considered low.

                  ‘More serious than we had hoped’: Bird flu deaths mount among California dairy cows
                  By Susanne Rust
                  Oct. 4, 2024 10:47 AM PT

                  As California struggles to contain an increasing number of H5N1 bird flu outbreaks at Central Valley dairy farms, veterinary experts and industry observers are voicing concern that the number of cattle deaths is far higher than anticipated.

                  Although dairy operators had been told to expect a mortality rate of less than 2%, preliminary reports suggest that between 10% and 15% of infected cattle are dying, according to veterinarians and dairy farmers.

                  “I was shocked the first time I encountered it in one of my herds,” said Maxwell Beal, a Central Valley-based veterinarian who has been treating infected herds in California since late August. “It was just like, wow. Production-wise, this is a lot more serious than than we had hoped. And health-wise, it’s a lot more serious than we had been led to believe.”​...
