Module 2 Flashcards
Forms of Contamination
What is fetal oral form of contamination?
It is when food service employees do not wash their hands and serve food after using the bathroom.
How can food contamination be passed?
From person to person.
What can cause contamination?
Prepping raw and ready-to-eat together, coughing sneezing and vomit, and stored incorrectly.
What are microorganisms?
Only viewable through microscopes, they are found everywhere. Most of them are harmless except for pathogens.
What are the four types?
Bacteria, viruses, parasites, and fungi (yeast and mold). There are forty different kinds that can cause foodborne illnesses.
What are the big six.
The big six are shigella spp, salmonella typhi, nontypical salmonella (nts), E. coli (stec), hepatitis A, and norovirus. They are highly contagious and can cause severe diseases.
What are common symptoms in foodborne illnesses?
Diarrhea, nausea, vomiting, abdominal cramps, fever, and jaundice.
What is onset time?
Onset time is the time it takes for symptoms of foodborne illnesses to appear in a person.
What does onset time depend on?
It depends on the type of illness and can range from 30 to 6 weeks. It can go from mild diarrhea to death.
What is bacteria?
It is the most important to understand. It can be found anywhere. In and outside our bodies. Some keep us healthy while others keep us sick. It cannot be seen, tasted, or smelled.
What is the best way to control foodborne illnesses?
Control time and temperature.
What does bacteria prefer?
Needing nutrients to survive, they prefer TCS foods.
What does bacteria grow best in?
Food with little to no acid.
How is acid measured?
It is measured using the pH scaling from 0-14. 0 is high acid, meanwhile 14 is high alkaline. Bacteria grow in neutral to slightly acidic food.
What temperature does bacteria grow in?
Bacteria grows in 41F to 135F (5C to 57C). This is the danger zone. The prime area is between 70F to 125F (21C to 52C). When held in this range, bacteria does not grow.
What does FAT TOM stand for?
Food, acidity, temperature, time, oxygen, and moisture.
How is salmonella typhi harmful?
Salmonella typhi only lives in humans. Eating just a small amount of it can get people sick. It can be found in ready-to-eat foods and beverages. To prevent this, wash your hands, properly cook food, and exclude those sick with it.
Can bacteria be found in feces?
Yes, and it can continue to be in feces long after being affected by it.
What is nontyphoidal salmonella?
It is the same as salmonella typhi. But it is in poultry, eggs, meat, dairy products, and produce.
Where is shigella spp?
It is found in feces and contaminated food. Flies that touch the feces can transfer it over.
Where is E. Coli found in?
E. Coli is found in cows. Which can contaminate meat when slaughtering. Once eaten, toxins enter the intestines making them sick. Raw and undercooked meat result in it.
What is up with viruses?
Viruses need a living host, but they can also transfer through food. Fecal oral is the most common way. So be sure to wash your hands.
What is norovirus?
It is the leading cause of foodborne illnesses. It is spread by airborne vomit particles.
What to do when someone has hepatitis A?
Keep them out of the food handling operation. It spreads via feces, contaminated water, and stuff like shellfish. You also get jaundice.
