Roos Foods of Kenton is expected to expand its voluntary recall of cheese to include sour cream products.

Roos Foods of Kenton is expected to expand its voluntary recall of cheese products, issued Feb. 23, to include sour cream products under the name Crema Pura Mexicana Cultured Sour Cream. Customers and food outlets should destroy these products immediately. 

The announcement was made March 4 through the state Division of Health and Social Services.

The cheese products have been linked to an outbreak of Listeria monocytogenes in other states, including Virginia, Maryland and California, including one fatality. No illnesses or deaths have been reported in Delaware.

While none of the Roos cheeses being recalled were found on Delaware shelves, the sour cream expected to be recalled was shipped to in-state locations. The Division of Public Health is alerting retail outlets and engaging in spot check visits to ensure no products remain on shelves. The sour cream products have not been found to contain Listeria in laboratory tests, but recent test results demonstrating bacteria within the factory has led to an expected voluntary recall of the sour cream.

Roos has ceased the production and distribution of the products as the federal Food and Drug Administration and the company continue their investigation as to what caused the contamination problem. While the FDA regulates cheese production, DPH has been working closely with the FDA, including on-site visits since the outbreak. In addition, DPH visited local retail stores out of an abundance of caution to confirm none of the recalled cheese products being sold in Delaware.

The recalled cheese products sold in other states linked to the problem are Mexicana, Amigo, Santa Rosa De Lima, and Anita.
