The #FDA Investigates #Listeria Outbreak Linked to Frozen Vegetables. #foodsafety

  • FDA Investigates Listeria Outbreak Linked to Frozen Vegetables

    On this page:
    The U.S. Food and Drug Administration along with the Centers for Disease Control and Prevention (CDC) and state and local officials are investigating listeriosis linked to frozen vegetables.
    What is the Problem and What is Being Done About It?
    The FDA, CDC and state and local officials are investigating a multi-state outbreak of listeriosis identified in March 2016.
    The CDC reports that eight people infected with the outbreak strains of Listeria monocytogenes have been reported from three states (California, Maryland and Washington) from September 2013 – March 2016. Ill people ranged in age from 56 to 86, with a median age of 76. Epidemiology 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 illnesses in this outbreak. As discussed further below, CRF Frozen Foods has initiated a recall of certain products.
    As part of a routine product sampling program the Ohio Department of Agriculture collected packages of frozen vegetable products from a retail location and isolated Listeria monocytogenes from True Goodness by Meijer brand frozen organic white sweet cut corn and frozen organic petite green peas. Both products were produced by CRF Frozen Foods.
    Whole genome sequencing showed that the Listeria monocytogenes isolate from the frozen corn was closely related genetically to seven bacterial isolates from ill people, and the Listeria monocytogenes isolate from the frozen peas was closely related genetically to one isolate from an ill person. This close genetic relationship provides additional evidence that the people in this outbreak became ill from eating frozen vegetables produced by CRF Frozen Foods.
    Based on the positive findings by the Ohio Department of Agriculture, on April 22, 2016, CRF recalled 11 frozen vegetable products because they may be contaminated with Listeria monocytogenes. On May 2, 2016, following a conversation between FDA, CDC and the firm, CRF Frozen Foods expanded its recall to include all of its frozen organic and traditional fruit and vegetable products manufactured or processed in CRF Frozen Foods’ Pasco facility since May 1, 2014. Approximately 358 consumer products sold under 42 separate brands were recalled.
    Additionally, March 2016 environmental samples collected by FDA from Oregon Potato Company, located in Pasco, WA, were found to be closely related genetically to seven of the isolates of ill people associated with this outbreak. Based on this information, Oregon Potato Company voluntarily recalled wholesale onion products, which led to subsequent downstream customer recalls, one disclaimer icon of which publicly disclosed Oregon Potato Company as its product source. FDA is working to identify other parts of the relevant supply chain that may have product relating to this outbreak. However, FDA is prohibited by law from releasing publicly certain information about supply chains, which may constitute confidential commercial information.
    FDA will continue to investigate to determine what, if any, connection exists between the product sample isolates and the environmental samples. This is a complex and ongoing investigation, and updates will be communicated as they become available.
    What are the Symptoms of Listeriosis?
    Listeriosis is a rare but serious illness usually caused by eating food contaminated with the bacteria calledListeria monocytogenes. Anyone who experiences fever and muscle aches, sometimes preceded by diarrhea or other gastrointestinal symptoms, or develops fever and chills while pregnant after eating any of the products listed below should seek medical care and tell the health care provider about eating the potentially contaminated frozen vegetables. Symptoms can appear from a few days up to a few weeks after consumption of the contaminated food.
    Who is at Risk?
    Listeriosis can be fatal, especially in certain high-risk groups. These groups include the elderly, and people with weakened immune systems and certain chronic medical conditions (such as cancer). In pregnant women, listeriosis can cause miscarriage, stillbirth, premature labor, and serious illness or death in newborn babies.
    What Specific Products were Recalled?
    On April 22, 2016, CRF Frozen Foods recalled 11 frozen vegetable products because they may be contaminated with Listeria. On May 2, 2016, CRF Frozen Foods expanded its recall to include all frozen organic and traditional fruit and vegetable products manufactured or processed in CRF Frozen Foods’ Pasco facility since May 1, 2014. Products have best by dates of April 26, 2016, thru April 26, 2018, and may have been purchased in all fifty U.S. states and the following Canadian Provinces: British Columbia, Alberta, Manitoba, Saskatchewan.
    Refer to FDA’s Recall Notice for the full list of CRF Frozen Foods that were recalled.
    What Do Restaurants and Retailers Need To Do?
    Retailers and restaurants should not serve any of the recalled products and should dispose of them. If they do not know the source of their frozen vegetable products, they should check with the supplier.
    Wash and sanitize display cases and refrigerators where potentially contaminated products were stored.
    Wash and sanitize cutting boards, surfaces, and utensils used to cut, serve, or store potentially contaminated products.
    Wash hands with warm water and soap following the cleaning and sanitation process.
    Retailers, restaurants, and other food service operators who have processed and packaged any potentially contaminated products need to be concerned about cross contamination of cutting surfaces and utensils through contact with the potentially contaminated products.
    Regular frequent cleaning and sanitizing of cutting boards and utensils used in processing may help to minimize the likelihood of cross-contamination.
    Listeria can grow at refrigeration temperatures in foods. Listeria can also cross contaminate other food cut and served on the same cutting board or stored in the same area.
    Retailers, restaurants, and other food service operators may wish to consider whether other foods available for sale could have been cross-contaminated from the potentially contaminated products, and should be discarded.
    Firms who have re-labeled, re-packed, or used the recalled products to produce new products that have not received a thermal kill step should contact the FDA Recall Coordinator in your state to determine whether or not you should initiate a new recall of your product(s). FDA District Recall Coordinators for each state are listed at: http://www.fda.gov/Safety/Recalls/IndustryGuidance/ucm129334.htm).
    What Do Consumers Need To Do?
    The FDA urges consumers to not eat any of the recalled products and to check their homes for the recalled fruit and frozen vegetable products. CRF Frozen Foods directs any consumers who have purchased any of the recalled products to return them to the place of purchase for a full refund, or discard them.
    Further, for frozen foods not listed in the recall, consumers should thoroughly cook them and follow microwave or conventional oven cooking instructions found on the package. Only thorough cooking will kill bacteria that can cause foodborne illness.
    Consumers should follow these simple steps:
    • Wash hands with warm water and soap for at least 20 seconds before and after handling food.
    • Wash the inside walls and shelves of the refrigerator, cutting boards and countertops; then sanitize them with a solution of one tablespoon of chlorine bleach to one gallon of hot water; then dry with a clean cloth or paper towel that has not been previously used.
    • Wipe up spills in the refrigerator immediately and clean the refrigerator regularly.
    • Always wash hands with warm water and soap following the cleaning and sanitization process.
    Additional recommendations for preventing listeriosis are available at the CDC Listeria website:http://www.cdc.gov/listeria/prevention.html.
