The agency was alerted to the issue when Indianapolis-based food distributor Caito Foods "received notification from their lettuce supplier, Fresh Express, that the chopped romaine that is used to manufacture some of their salads and wraps was being recalled".
The affected products include the Trader Joe's Tarragon Chicken Salad Wrap, the Trader Giotto's Caesar Salad with Chicken and Trader Ming's Chinese Inspired Salad with Chicken that contain best by dates between July 21 and July 23.
The products under recall were sold by grocery stores nationwide, including Kroger, Trader Joe's and Walgreens, according to CNN.
Just when you thought it was safe to eat salad again, there's news that more salad products may be contaminated - this time, with a parasite called Cyclospora.
Consumers are urged to throw them away or return them to stores for a refund.
Symptoms of Cyclospora infection include watery diarrhea, loss of appetite and weight, cramping, bloating or increased gas, nausea, fatigue, and low-grade fever. A Walgreens spokesperson told TIME that affected products were available only at a "limited number" of stores in IL, and were immediately pulled from store shelves upon learning of the recall.
