Defining Food-Borne Illnesses● An illness caused by consuming contaminated foods or

beverages.● Food-borne illness is also called foodborne disease, foodborne

infection or food poisoning.● More than 250 different foodborne diseases have been

described. Most of these diseases are infections, caused by a variety of bacteria, viruses, and parasites that can be foodborne.

● Symptoms vary with type of infection, but may include nausea, vomiting, abdominal cramps and diarrhea.

● Many microbes can be spread in a variety of ways, so we can’t always know that a disease is food-borne. Public health officials need to know how the disease has been spread in order to take the proper steps to stop it.

Why Should We Care about Food-Borne Illnesses?In 2011 the CDC estimated that EACH YEAR in the US there are:● 48 million individual cases of Food-Borne

Illness (1 in 6 Americans)● Over 128,000 hospitalizations ● About 3000 deaths

Page 4: Lab Sanitation Procedures to Prevent Food-Borne Illness

Causes of Food-Borne Illness● Food contaminated by illness-causing bacteria including

Campylobacter, Cryptosporidium, Listeria and Salmonella. ● Food contaminated with non-food items such as cleansers,

pesticides, naturally occurring toxins in the plant or animal. Some examples include:● consuming poisonous mushrooms ● broken glass accidentally entering food● cleaning chemicals used near food and contaminating it

● Bacteria in food which create toxins as they multiply in the gut. Some toxin creating bacteria include E. coli O157, Shigella, Vibrio and Yersinia.

Preventing Time Temperature Abuse

Time Temperature Abuse happens when food:● Is not heated to a high enough temperature to kill

microorganisms.● Is not stored or held at required temperatures.● Is not correctly cooled.● Anytime food is kept at temperatures favorable for

microorganisms to grow.

Temperature of Food is Important!

● Keep hot foods hot and cold foods cold.

● Cook foods to the proper internal temperature.

● Minimize time spent in the danger zone to control bacterial growth.

155 F⁰

Refrigerator Temperature

Freezer Temperature

Cooked fruit & vegetables

Roasts

Chicken, stuffing, leftovers

Ground meats

Page 8: Lab Sanitation Procedures to Prevent Food-Borne Illness

Cooling Food GuidelinesCool food according to the following guidelines: ● In the first 2 hours cool food

to 70⁰ F.● In the next 4 hours, food

must chill to 40⁰ or below to remain safe to eat.

Chilled food that will be reheated must reach an internal temperature of 165⁰.

To cool food quickly, it should be no more than two inches in depth.

● 80% of all infectious diseases are transmitted by touch.● Only 67% of people wash their hands after using the restroom.● The CDC recommends that hands be washed for 15-30

seconds, most wash for 9 seconds.● We have between 2 and 10 million bacteria between our

fingertips and elbow.● Damp hands spread 1,000 times more germs than dry hands.● Germs can live on your hands for up to 3 hours.● It is estimated that washing hands with soap and water could

reduce diarrheal disease-associated deaths by up to 50%

Hand Sanitizers● Not necessary to clean hands● If you choose to use them, they must be used in addition

to, not as a replacement of, regular handwashing. ● Nothing removes germs better than soap and water.● If hand sanitizers are used, sanitizer must be completely

dry on the hands before touching food products.● Usually people want to use the hand sanitizers because

they think it is faster…but, it isn’t!

must be monitored. ● If you use a mechanical dishwasher, you must

know how to use it and how to check that it’s sanitizing properly.
