1.02 Identify foodborne contaminates
2
Microbial contaminants
Virus Parasites Microbial contaminants Fungi Bacteria
3
Foodborne Microorganisms
Pose the greatest threat to food safety.
4
Bacteria Greatest concern to food safety
5
Temperature Acidity Food FAT TOM Moisture Time Oxygen
6
Raise or lower food temperature
Make food more acidic Raise or lower food temperature Controlling Growth of Microorganism Lower the water activity of food Limit the amount of time food is in the temperature danger zone
7
Staphylococcal Aureus
Shigellosis Salmonellosis Listeriosis Bacteria e. coli Clostridium perfringens Bacillus cereus Vibrio Staphylococcal Aureus Botulism Campylobacteriosis
8
E.coli Toxin-mediated Bacteria Lives in the intestines of cattle
Diarrhea, abdominal cramps, vomiting, may cause kidney failure Toxin-mediated E.coli Bacteria Lives in the intestines of cattle Make sure ground beef is cooked to 155 degrees for 15 seconds and avoid cross contamination
9
Diarrhea, fever, chills abdominal cramps, vomiting, headaches
infection Vibrio Bacteria Oysters
10
Intoxication Staphlococcus aureus Bacteria
Nausea, retching, abdominal cramps, diarrhea, headache Intoxication Staphlococcus aureus Bacteria Protein based salads, reheated food,
11
Viruses Smallest of the microbial contaminants
Hepatitis A, Norwalk virus, Rotavirus Viruses May survive cooking and freezing Clean and sanitize food-contact surfaces, practice good personal hygiene, Use sanitary, chlorinated water source
12
Hepatitis A Fatigue, headache, loss of appetite, vomiting, jaundice
Infection Hepatitis A Virus Shellfish and salads
13
Parasites Killed by proper freezing or cooking
Trichinosis, Anisakias, Giardiasis, Toxoplasmosis Parasites Survival depends on a host Grow natural in some animals
14
Found naturally in air, soil, plants, animals, water and some foods
Mushrooms Fungi Yeasts Molds
15
Temperature Danger Zone
41 – 135 degrees
16
Foodborne infections Person eats food containing pathogens which then grow in the intestines Symptoms do not appear immediately
17
Foodborne intoxication
Person eats food containing toxins that cause illness Symptoms appear quickly within a few hours
18
Foodborne Toxin-mediated Person eats food containing pathogens which then produce illness-causing toxins in the intestines Longest on site
