Food Safety Flashcards
What FIVE factors can cause bacteria to grow? (5 marks)
NOT LINKED WITH CROSS-CONTAMINATION
- Warm temperature = bacteria will grow in warm temperature
- the Longer amount of time = more time for bacteria to grow
- pH - Acidic foods will last longer
- Type of food - protein will go off quicker carbohydrates
- Moisture - more moisture, more room for bacteria to grow
How many degrees in the freezing/frozen phase?
-20
Why do we freeze food?
Longer shelf life, bacteria cannot grow when food is frozen (freezer)
What temperature is food chilled at?
-15 - 0
Examples of food that can be stored in ambient temperature
Bread, Canned Foods, Pasta, Cereal
Why can canned foods last for a year?
Canned foods are sealed and heated to kill off all microorganisms
Why is vinegar used to pickle foods like eggs, onions and pickles?
Vinegar is acidic which can stop bacteria from growing

Which date mark is a safety warning?

What is cross-contamination?
A breach in hygiene which causes the food to become unsafe.
What are four examples of cross contamination?
Dirty equipment, People, Pests, Raw Meat
How can people contaminate food?
Not washing hands after sneezing or coughing.
How can raw meat contaminate food?

What things do we do to help prepare food in a hygienic way?
Wash your hands before cooking Wear an apron Tie long hair back Use correct coded cooking boards Use correct knives Clean surface area
What do we do to check the food is cooked properly?
Use a temperature probe to check if food is cooked
Use a fork or knife to poke your food to see if it goes all the way through
How do we best serve food?
Serving food to be eaten in 90 mins
If the food is not eaten, it needs to be left to cool down for 90 mins before being stored in cold (fridge/freezer)
Make sure food is covered so that pests do not contaminate food
What are the three hygiene and safety procedures whilst dealing with food?

Campylobacter
Where does E. coli O157 originate from?
