Maybe the healthy choice might not be so healthy? Federal officials are warning American consumers not to buy more than two dozen types of salad and wraps sold by the Kroger supermarket chain, Trader Joe’s, and Walgreens because of concerns about a possible parasite contamination. The Department of Agriculture’s Food Safety and Inspection Service advised certain beef, pork and poultry salads and wraps might be contaminated with cyclospora. The parasite can cause diarrhea, vomiting, headache, fever, loss of appetite, weight loss, and stomach pain. The USDA said the issue was discovered when Indianapolis-based food distributor Caito Foods “received notification from its lettuce supplier, Fresh Express, that the chopped romaine that is used to manufacture some of their salads and wraps was being recalled.” The full list of affected products can be viewed on the USDA website.
