The milk used in Publix’s mixes has tested positive for the bacterium, and the Federal Drug Administration (FDA) has found traces of Salmonella at the facility where the powdered buttermilk used in Stonewall’s mixes is made. However, according to the FDA notice, the pathogen hasn’t been found in the powdered products supplied to Stonewall Kitchen by the ingredient manufacturer.

Neither of the company’s finished products have tested positive for Salmonella, and there haven’t been any reported illnesses, either. However, both companies are recalling their products as a precaution.

Salmonella is an illness that can cause diarrhea, fever, and abdominal cramps. Although most people can recover without treatment, some patients need hospitalization. The elderly, infants, and those with “impaired immune systems” are more likely to have a severe complications, the FDA reports.

Publix stores in Florida, Georgia, Alabama, South Carolina, Tennessee, and North Carolina were sold the potentially affected mixes, the FDA announced. The flavors that are possibly contaminated include: Banana-Flavored Chocolate Chip, Pumpkin, and Blueberry.
