The Delaware Division of Public Health is advising Delawareans of a multistate outbreak of listeria infections linked to deli ham.

Several companies have recalled ham products that could be contaminated with listeria monocytogenes bacteria and could make people sick. To date, there have been no confirmed cases reported in Delaware, but DPH urges consumers to take precautions to prevent illness. Listeria is particularly harmful to pregnant women.

According to the Centers for Disease Control and Prevention, four people infected with the outbreak strain of listeria monocytogenes have been reported in North Carolina and Virginia. All four had been hospitalized and one death was reported by Virginia health officials.

Consumers who have any of these recalled products at home should not eat them, even if some of it was consumed and no one has gotten sick. If the purchase date is unknown, do not eat it. Before purchasing deli ham at a grocery store or eating it at a restaurant, consumers should confirm with the store or restaurant that it is not one of the recalled products.

Restaurants and retailers should not serve or sell any of the recalled products. Retailers should also clean and sanitize deli slicers and other areas where recalled deli ham was prepared, stored or served. Follow the manufacturer’s recommendations for sanitizer strength and application to ensure it is effective. For more, visit bit.ly/2OBHxMs.

People with invasive listeriosis usually report symptoms starting one to four weeks after eating food contaminated with listeria. Pregnant women and their newborns, adults age 65 and older, and people with weakened immune systems are more likely to get sick with listeriosis. The symptoms differ for pregnant women compared to non-pregnant individuals.

Pregnant women typically experience only fever and other flu-like symptoms, such as fatigue and muscle aches. However, infections during pregnancy can lead to miscarriage, stillbirth, premature delivery or life-threatening infection of the newborn. For people other than pregnant women, symptoms can include headache, stiff neck, confusion, loss of balance and convulsions, in addition to fever and muscle aches.

Anyone who experiences these symptoms should seek emergency medical care. Medical providers should report suspected cases of listeria to the DPH Office of Infectious Disease Epidemiology at 744-4990 or 24/7 at 888-295-5156.
