Fruit, vegetables, dairy products, meat and other food items can come into contact with soil, water, human/animal waste that contains illness-causing germs. Foodborne illness can be caused when food is not kept at the correct temperature and a germ in a food is allowed to multiply.
Are bacteria in food always harmful?
Bacteria, viruses and parasites are the sources of many food poisoning cases, usually due to improper food handling. Some bacteria, in small amounts, are not harmful to most healthy adults because the human body is equipped to fight them off.
What two things does bacteria need to multiply?
All bacteria need is food and moisture to survive. Time; we know is needed, to allow them to multiply. The temperature has to be right for the specific type of bacteria, but most like temperatures within what we call the ‘danger zone’.
What is the best way to kill bacteria in food?
Most foods, especially meat, poultry, fish and eggs, should be cooked thoroughly to kill most types of food poisoning bacteria. In general, food should be cooked to a temperature of at least 75 °C or hotter.

Foods that pose the highest risk of bacterial contamination include leafy greens, bean sprouts, leftover rice, unpasteurized milk, soft cheeses, and deli meats, as well as raw eggs, poultry, meat, and seafood ( 7 ).
How do foods become contaminated?
Food and kitchen tools and surfaces may become contaminated from raw food products (i.e., meat and poultry). Microbes can be transferred from one food to another by using the same knife, cutting board or other utensil without washing the surface or utensil in between uses.
What are 3 examples of cross contamination?
Some examples are: Handling foods after using the toilet without first properly washing hands. Touching raw meats and then preparing vegetables without washing hands between tasks. Using an apron to wipe hands between handling different foods, or wiping a counter with a towel and then using it to dry hands.

Which type of contamination escalates gets bigger when food is left out too long?
If that food is “perishable”—meaning a food that should be refrigerated to prevent bacteria from multiplying at room temperature—then a foodborne illness is possible if the food is “temperature abused.” When contaminated food is left out more than two hours at room temperature, Staph aureus begins to grow and will …
What happens if you find a hair in your food?

What is the temperature danger zone for food?
Bacteria grow most rapidly in the range of temperatures between 40 °F and 140 °F, doubling in number in as little as 20 minutes. This range of temperatures is often called the “Danger Zone.” Never leave food out of refrigeration over 2 hours.
What do you mean by food contamination?
Food contamination is generally defined as foods that are spoiled or tainted because they either contain microorganisms, such as bacteria or parasites, or toxic substances that make them unfit for consumption. A food contaminant can be biological, chemical or physical in nature, with the former being more common.

What are 5 physical contaminants?
Physical contamination occurs when physical objects contaminate food. Common physical contaminants include hair, glass, metal, pests, jewellery, dirt and fake nails.
What are the effect of eating contaminated food?
Foodborne pathogens can cause severe diarrhoea or debilitating infections including meningitis. Chemical contamination can lead to acute poisoning or long-term diseases, such as cancer. Foodborne diseases may lead to long-lasting disability and death.
