What You Should Do

Do not eat any recalled packaged salads.

  • Throw them away or return them to where you bought them.
  • Follow these five steps to clean your refrigerator, items, and surfaces that may have touched the recalled products. Listeria can survive in the refrigerator and can easily spread to other foods and surfaces.

Call your healthcare provider right away if you have these symptoms after eating packaged salads.

  • Pregnant people usually experience only fever, fatigue, and muscle aches. However, Listeria can cause pregnancy loss or premature birth. It can also cause serious illness or death in newborns.
  • People who are not pregnant may experience headache, stiff neck, confusion, loss of balance, and convulsions, in addition to fever and muscle aches.

Stay up to date on this outbreak by following CDC on Facebook or Twitter.

  • Share the latest outbreak information with your friends and family who are at higher risk of getting sick from Listeria (aged 65 and older, are pregnant, or have a weakened immune system).

Symptoms of Listeria
  • Listeria can cause severe illness (known as invasive listeriosis) when the bacteria spread beyond the gut to other parts of the body.
    • Adults 65 years and older, pregnant people, and people with weakened immune systems are at higher risk for severe illness.
  • Symptoms of severe illness usually start 1 to 4 weeks after eating contaminated food. However, symptoms can start as late as 10 weeks after.
    • Pregnant people usually experience only fever, fatigue, and muscle aches. However, Listeria can cause pregnancy loss or premature birth. It can also cause serious illness or death in newborns.
    • People who are not pregnant may experience headache, stiff neck, confusion, loss of balance, and convulsions, in addition to fever and muscle aches.
  • Listeria can also cause common food poisoning symptoms, like diarrhea and fever. People who experience these symptoms usually recover without treatment.
