Produce supplier Taylor Farms is recalling iceberg lettuce shipped to 27 US states because of potential contamination with cyclospora, the parasite causing thousands of cases of diarrhea across the country.

The company said it’s “actively removing” the products, has suspended distribution of iceberg lettuce from Central Mexico to the United States and is no longer receiving products from the implicated lot.

“Consumers who have purchased the recalled iceberg lettuce should discard it immediately and not consume it,” the company said.

Taylor Farms said the shredded iceberg lettuce product was distributed June 29 through July 16 in Alabama, Arkansas, Connecticut, Florida, Georgia, Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Michigan, Missouri, Mississippi, North Carolina, New Hampshire, New Jersey, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia and Wisconsin.

The recall notice includes brand abbreviations and some product descriptions, including use-by dates, but does not mention specific retailers, restaurants or product names.
