big-map-5-3-16Since March 2016, CDC has been collaborating with public health officials in several states and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Listeria monocytogenes infections (listeriosis).

Eight people infected with the outbreak strains of Listeria have been reported from three states since September 13, 2013. All eight people were hospitalized, including one from Maryland and one from Washington who died, although listeriosis was not considered to be a cause of death for either person.

Epidemiologic and laboratory evidence available at this time indicates that frozen vegetables produced by CRF Frozen Foods of Pasco, Washington and sold under various brand names are one likely source of illness in this outbreak.

Investigations are ongoing to determine if food sources used to manufacture CRF Frozen Foods products could explain some of the illnesses. On April 23, 2016, CRF Frozen Foods recalled 11 frozen vegetable products because they may be contaminated with Listeria. On May 2, 2016, CRF Frozen Foods expanded the initial recall to include all organic and traditional frozen vegetable and fruit products processed in its Pasco, Washington facility since May 1, 2014. Approximately 358 consumer products sold under 42 separate brands were recalled. Recalled items were sold nationwide and in Canada. A complete table of recalled products is on the FDA website.

CDC recommends that consumers do not eat, and restaurants and retailers do not serve or sell, recalled organic and traditional frozen vegetables and fruit products.
