A new foodborne illness outbreak taking place in multiple states is, according to Food Safety Magazine, being investigated by federal officials, with turkey products identified as the likely source.

The U.S. Department of Agriculture’s Food Safety and Inspection Service indicated the cause of the outbreak in its investigation table as “Salmonella Hadar, turkey suspect.”

A U.S. Centers for Disease Control and Prevention (CDC) spokeswoman confirmed that the CDC is investigating the outbreak. As of March 15, there have been 22 patients reported across nine states. 

Turkey has been the source of food poisoning outbreaks in the United States in both 2018 and 2019 investigations, involving Salmonella Reading and Salmonella Schwarzengrund, respectively. According to the CDC, the 2019 Salmonella outbreak sickened at least seven people in three states.

The 2018 outbreak involved at least 358 people in the United States who became sick, across 42 states. One death was confirmed, and the illnesses were linked to raw human and pet foods from many sources, including Jennie-O turkey, which recalled some of its products. At the same time in 2018, Canadian officials investigated an outbreak of Salmonella Reading linked to poultry products. Testing showed the same strain on both side of the U.S./Canada border.
