Since the first reported case of listeriosis in January 2017, the disease has claimed the lives of 180 people.

Safe food practices in our homes are very critical, for instance, if you were to cook a product, you really want to get it cooled and into the refrigerator within about two hours.— Lizette, 702/Cape Talker caller, Microbiologist
She also urged listeners to clean their fridges, wash vegetables before eating them and to heat meats thoroughly.
Don't reheat food that you previously cooked. If you reheat previously cooked food, eat it and throw it out.— Lizette, 702/Cape Talker caller, Microbiologist
