History of Meat and Cheese Listeria Monocytogenes Outbreaks
There is a new deadly Listeria monocytogenes outbreak that is linked to deli meats and cheeses. Ten people are sick in three states, including Florida, Massachusetts, and New York, and one person who lived in Florida has died. All ten patients were hospitalized.

Protect Yourself Against Listeria Outbreak Linked to Deli Meat Cheese

Once it has been introduced into a facility, especially a moist and cool environment, it can become established and be very difficult to get rid of. The pathogen can hide in floor cracks, grease traps, air vents, in machines and surfaces that are difficult to clean, on food preparation … [Read more...]
