California’s ‘Egg Basket’ impacted due to bird flu outbreaks in U.S. – CGTN

A year after the bird flu led to record egg prices and widespread shortages, the disease known as highly pathogenic avian influenza is wreaking havoc in the U.S. state of California, which escaped the earlier wave of outbreaks that devastated poultry farms in the Midwest.

The highly contagious virus has ravaged Sonoma County, where officials have declared a state of emergency.

Following government rules, Mike Weber's company, Sunrise Farms, had to slaughter its entire flock of egg-laying hens 550,000 birds to prevent the disease from infecting other farms in Sonoma County north of San Francisco.

During the past two months, nearly a dozen commercial farms have had to destroy more than 1 million birds to control the outbreak, dealing an economic blow to farmers, workers and their customers.

Merced County in Central California also has been hit hard, with outbreaks at several large commercial egg-producing farms in recent weeks.

Experts say bird flu is spread by ducks, geese and other migratory birds. The waterfowl can carry the virus without getting sick and easily spread it through their droppings to chicken and turkey farms and backyard flocks through droppings and nasal discharges.

California poultry farms are implementing strict biosecurity measures to curb the spread of the disease. State Veterinarian Annette Jones urged farmers to keep their flocks indoors until June, including organic chickens that are required to have outdoor access.

The loss of local hens led to a spike in egg prices in the San Francisco Bay Area over the holidays before supermarkets and restaurants found suppliers from outside the region.

While bird flu has been around for decades, the current outbreak of the virus that began in early 2022 has prompted officials to slaughter nearly 82 million birds, mostly egg-laying chickens, in 47 U.S. states, according to the U.S. Department of Agriculture. Whenever the disease is found the entire flock is slaughtered to help limit the spread of the virus.

The price of a dozen eggs more than doubled to $4.82 at its peak in January 2023. Egg prices returned to their normal range as egg producers built up their flocks and outbreaks were controlled. Turkey and chicken prices also spiked, partly due to the virus.

Climate change is increasing the risk of outbreaks as changing weather patterns disrupt the migratory patterns of wild birds, said Maurice Pitesky, a poultry expert at the University of California, Davis. For example, exceptional rainfall last year created new waterfowl habitat throughout California, including areas close to poultry farms.

"We have wild birds that are full of virus. And if you expose your birds to these wild birds, they might get infected and ill," said Rodrigo Gallardo, a UC Davis researcher who studies avian influenza.

Gallardo advises the owners of backyard chickens to wear clean clothes and shoes to protect their flocks from getting infected. If an unusual number of chickens die, they should be tested for avian flu.

Ettamarie Peterson, a retired teacher in Petaluma, has a flock of about 50 chickens that produce eggs she sells from her backyard barn for 50 cents each.

"I'm very concerned because this avian flu is transmitted by wild birds, and there's no way I can stop the wild birds from coming through and leaving the disease behind," Peterson said. "If your flock has any cases of it, you have to destroy the whole flock."
