The U.S. Centers for Disease Control (CDC) and public health and regulatory officials in several states, and the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA-FSIS) are investigating a multistate outbreak of Listeria monocytogenes infections linked to pork products produced by 165368 C. Corporation, doing business as Long Phung Food Products.

On November 20, 2018, 165368 C. Corporation, doing business as Long Phung Food Products in Houston, TX recalled ready-to-eat pork products because they might be contaminated with Listeria.

Do not eat, sell, or serve recalled products from Long Phung Food Products.

The full list of recalled ready-to-eat pork patty rolls is on the USDA-FSIS website.

Recalled products are labeled with establishment number “EST. 13561” inside the USDA mark of inspection.

Recalled pork patty rolls were produced on various dates from May 21, 2018, through Nov. 16, 2018. These items were shipped to distributors and retail locations nationwide.

Return any recalled pork products to the store for a refund or throw them away. Even if some of the product was eaten and no one got sick, do not eat it. If you do not know if the pork product you purchased was recalled, ask the place where you purchased it or throw it away.

Wash and sanitize drawers or shelves in refrigerators and freezers where recalled pork products were stored. Follow these five steps to clean your refrigerator.

Retailers should clean and sanitize deli slicers and other areas where recalled pork products were prepared, stored, or served. Follow the manufacturer’s recommendations for sanitizer strength and application to ensure it is effective.

If you develop symptoms of a Listeria infection  after eating recalled pork products, contact a healthcare provider and tell them you ate recalled pork products. This is especially important if you are pregnant, age 65 or older, or have a weakened immune system.

Four people infected with the outbreak strain of Listeria monocytogenes have been reported from four states.

Listeria specimens from ill people were collected from July 1, 2017, to October 24, 2018.

Four people have been hospitalized. No deaths have been reported.

Epidemiologic and laboratory evidence indicates that pork products from 165368 C. Corporation, doing business as Long Phung Food Products are a likely source of the outbreak.

On November 20, 2018, 165368 C. Corporation, doing business as Long Phung Food Products recalled ready-to-eat pork products because they might be contaminated with Listeria.
