The U.S. Centers for Disease Control and Prevention reports:

• CDC is collaborating with public health officials in several states and with the U.S. Food and Drug Administration (FDA) to investigate an outbreak of Listeria monocytogenes infections (listeriosis) linked to commercially produced, prepackaged caramel apples. Listeria can cause a serious, life-threatening illness.
• On January 6, 2015, Bidart Bros. of Bakersfield, California voluntarily recalled Granny Smith and Gala apples because environmental testing revealed contamination with Listeria monocytogenes at the firm’s apple-packing facility.
• Consumers should not eat any recalled Granny Smith and Gala apples produced by Bidart Bros., and retailers should not sell or serve them.
• Consumers who are buying or have recently bought Granny Smith or Gala apples can ask their retailers if the apples came from Bidart Bros.
• The information CDC has at this time indicates that commercially produced, prepackaged caramel apples may be contaminated with Listeria and may be causing this outbreak.
• Happy Apples, California Snack Foods, and Merb’s Candies each announced a voluntary recall of commercially produced, prepackaged caramel apples after hearing from Bidart Bros., an apple supplier, that there may be a connection between Bidart Bros. apples and this listeriosis outbreak.
• Investigators are continuing to work to determine if any other brands or types of commercially produced, prepackaged caramel apples are linked to illnesses.
• CDC continues to recommend that U.S. consumers do not eat any commercially produced, prepackaged caramel apples, including plain caramel apples as well as those containing nuts, sprinkles, chocolate, or other toppings, until more specific guidance can be provided.
• Although caramel apples are often a fall seasonal product, contaminated commercially produced, prepackaged caramel apples may still be for sale at grocery stores and other retailers nationwide or may be in consumers’ homes.
• As of January 8, 2015, a total of 32 people infected with the outbreak strains of Listeria monocytogenes had been reported from 11 states.
• Thirty-one ill people have been hospitalized, and six deaths have been reported. Listeriosis contributed to at least three of these deaths.
• Ten illnesses were pregnancy-related (occurred in a pregnant woman or her newborn infant), with one illness resulting in a fetal loss.
• Three invasive illnesses (meningitis) were among otherwise healthy children aged 5–15 years.
• To date, 23 (88%) of the 26 ill people interviewed reported eating commercially produced, prepackaged caramel apples before becoming ill.
• The Public Health Agency of Canada (PHAC) has identified 2 cases of listeriosis in Canada with the same pulsed-field gel electrophoresis (PFGE) patterns as seen in the U.S. outbreak.
• PHAC is working with its provincial and territorial partners to determine the source of these illnesses.
• This investigation is rapidly evolving, and new information will be provided as it becomes available.
