The CDC reported that the Listeria outbreak linked to Deli Meat and Cheese is over

An outbreak of Listeria monocytogenes was linked to Deli meats (cold cuts, lunch meats, hot dogs, and pâtés) and deli-sliced cheeses. The outbreak caused 16 illnesses, 13 hospitalizations, and one death. Deli meats and cut cheeses are known sources of Listeria illnesses. Listeria can easily spread among food, food preparation surfaces like deli slicers, and hands, and therefore is difficult to detect. Also, Listeria is a hardy bacterium that can be difficult to remove once it is present in a deli or a food processing facility. It can survive and grow at cold temperatures in a refrigerator. CDC data showed that deli meat and cheese bought at deli counters in multiple states were the likely sources of this outbreak. The outbreak strain of Listeria was found in open packages of mortadella, ham, and salami sliced at the deli and a deli in Brooklyn, New York. A single deli or food source was not identified. Probably because Listeria spreads easily between food and the deli environment, and it can live for a long time in deli display cases and on equipment. A contaminated food likely introduced the outbreak strain of Listeria into delis in multiple states.@ https://www.cdc.gov/listeria/outbreaks/deli-11-22/index.html#:~:text=This%20outbreak%20is%20over.,hot%20to%20kill%20any%20germs
