A CDC food safety alert regarding a multistate outbreak of Salmonella Typhimurium infections has been posted: https://www.cdc.gov/salmonella/typhimurium-07-21/index.html

Key points:

Eight people infected with the outbreak strain of Salmonella Typhimurium have been reported from two states (Wisconsin and Illinois). No hospitalizations or deaths have been reported.
Interviews with ill people and traceback information show that BrightFarms brand Sunny Crunch salad may be contaminated with Salmonella and making people sick. At least five people ate or bought this product before getting sick.
The true number of sick people in an outbreak is likely higher than the number reported, and the outbreak may not be limited to the states with known illnesses. This is because some people recover without medical care and are not tested for Salmonella.
Investigators are working to identify if additional products are contaminated.
CDC is advising people not to eat, sell, or serve BrightFarms brand Sunny Crunch salad. See the Food Safety Alert for product details and description.
