Listeriosis is a disease that the CDC staff, public health departments and medical people work together to identify source of outbreaks and remove the contaminated food from the market.
Listeria germs can grow in food while in a person’s refrigerator. The CDC staff recommends using a refrigerator thermometer to ensure your refrigerator stays at a temperature of 40OF or lower. The freezer compartment should be 0OF or lower.
Another safe food tip says clean up spills (especially juice from raw meat, poultry, even hot dog and lunch meats) in your refrigerator with hot water and liquid soap, before rinsing with water.
Eat leftovers within 3-4 days. Divide leftover food into shallow containers. Use airtight lids or coverings.
Throw away outdated foods; notice the ‘use by’ date and do not eat expired food. More details about safe food practices can be found at http://www.cdc.gov/nczved/divisions/dfbmd/diseases/listeriosis/
