Title Nationwide Listeria Outbreak from Cheese Products
Introduction EMSL Analytical, Inc. offers testing services to identify the presence of Listeria prior to outbreaks.

Cinnaminson, New Jersey, February 27, 2026

It was recently announced that the United States Food and Drug Administration (FDA) has recalled grated cheese processed from a New Jersey facility due to tests returning positive for Listeria monocytogenes. The recall covers about 11,530 units of Pecorino Romano cheese distributed nationwide.

Listeria monocytogenes (L. monocytogenes) is a bacteria associated with foods like raw milk, supposedly pasteurized fluid milk, cheeses (particularly soft-ripened varieties), ice cream, raw vegetables, fermented raw-meat sausages, raw and cooked poultry, raw meats (all types), and raw and smoked fish. L. monocytogenes is often transmitted during the production of these food products.

“Although the recent Class I recall for Pecorino Romano with links to Listeria is extremely unfortunate, it is something EMSL is equipped to help prevent from occurring in the future” said Joseph Frasca, Vice President of Marketing at EMSL Analytical, Inc. “At EMSL, we offer advanced testing techniques to identify Listeria and other foodborne pathogens in contaminated foods before they make it to market.”

EMSL Analytical, Inc. offers a wide range of testing services for microbial pathogens and can identify Listeria, SalmonellaE. coli O157H7, and other contaminants. These tests can be utilized to assess raw materials, finished products, and production surfaces. Testing is also instrumental for evaluating cleaning and disinfection procedures at processing, production, and manufacturing facilities.
