A multistate outbreak of Listeria monocytogenes infections in the USA that has been linked to frozen vegetables produced by CRF Frozen Foods of Pasco, Washington, has led to a series of large product recalls by other food manufacturers that have used frozen vegetables supplied by the company in their own products.
The outbreak has affected at least eight people from three states since 13 September 2013. Interviews with three of the people affected by the outbreak revealed that two of them had eaten Organic by Nature brand frozen vegetables in the month before they became ill. This brand is produced by CRF Frozen Foods. Listeria has also been isolated from other brands of frozen vegetables produced by CRF Frozen Foods.
The company recalled various products on 23 April and then expanded the recall to include all organic and traditional frozen vegetable and fruit products processed at its Pasco facility since 1 May 2014. These products were sold under a variety of brand names nationwide and in Canada.
Several other recalls associated with frozen vegetables from CRF Frozen Foods have now been initiated. The largest is the recall of more than 47 million pounds of frozen meat and poultry products produced by Ajinomoto Windsor Inc. According to the USDA Food Safety and Inspection Service, Ajinomoto is recalling more than 30 frozen, not-ready-to-eat meat and poultry products, such as chicken fried rice, sold nationwide and exported to Canada and Mexico under various brand names. The products are heat-treated but not fully cooked and may contain frozen vegetables as ingredients.
