Bird Flu Identified in Mississippi Poultry


Since January 2022, over 125 million instances of bird flu have been identified in the U.S., affecting wild aquatic birds, commercial poultry, and backyard flocks.

A commercial poultry breeder in Mississippi has reported positive tests for bird flu, as stated by state officials.

The Mississippi Board of Animal Health (MBAH) was informed by the U.S. Department of Agriculture’s (USDA) National Veterinary Services Laboratory that the poultry from a southeast Mississippi breeder tested positive for the H5N1 strain of bird flu, following sample analysis at a federal laboratory, according to an MBAH statement released on Monday.

The MBAH indicated that the affected birds were “depopulated to prevent further spread,” and the area has since been quarantined.

According to the MBAH, the infected poultry did not enter the food supply, and there is no food safety risk related to bird flu when chicken and eggs are “handled and cooked properly.”

As reported by the Centers for Disease Control and Prevention (CDC), instances of bird flu have been detected in poultry, dairy cows, milk, and among dairy and poultry staff, with the public health risk considered low.

The CDC has confirmed that over 125 million cases of bird flu have been found in wild aquatic birds, commercial poultry, and backyard flocks since January 2022.

On December 18, the CDC reported that a Louisiana resident became the first of the 61 recorded human cases since April to require hospitalization due to a severe case of bird flu.

This infection was linked to contact with sick or deceased birds in a backyard flock, as the CDC stated, indicating that “in addition to affected commercial poultry and dairy operations, wild birds and backyard flocks can be sources of exposure.”

Among the reported human bird flu cases, 34 occurred in California.

In response to a surge of cases in southern California’s dairy cows, California Governor Gavin Newsom declared a state of emergency on December 18.

Governor Newsom stated that the goal of the proclamation was to allocate government resources for a swift response.

“Building on California’s extensive testing and monitoring system—the largest in the country—we are dedicated to further ensuring public health, supporting our agricultural industry, and providing Californians with accurate and timely information,” Newsom explained.

Bird flu was first identified in wild birds in South Carolina and California in 2022 and was reported in dairy cows in Texas and Kansas in March 2024, according to the governor’s announcement.

In August 2024, bird flu was discovered in dairy cows in central California, leading state public health authorities to take action.

“While the public remains at low risk, we will continue to implement all necessary measures to prevent the virus’s spread,” stated Newsom.
