What are the 4 common sources of cross contamination?

Contaminants aren’t always introduced to food directly. Cross-contamination is the accidental transfer of contaminants into the food from a surface, object, or person. Four common sources of cross-contamination include clothing, utensils, food handlers, and pests.

What are contamination hazards?

A hazardous contaminant is any hazardous substance whose presence in an environment is undesirable and poses a risk to workers in that environment. When an environment becomes contaminated with a hazardous substance, the environment itself becomes hazardous due to the presence of the contaminant.

How many types of hazards are there?

What is cross contamination?

Cross-contamination is the physical movement or transfer of harmful bacteria from one person, object or place to another. Preventing cross-contamination is a key factor in preventing foodborne illness.

Which is a physical contaminant?

Physical contaminants (or ‘foreign bodies’) are objects such as hair, plant stalks or pieces of plastic/metal that can occur as contaminants in food. Sometimes the object is a natural component of the food (e.g. a fruit stalk) – but in all cases it is important to find out what it is and how and when it got there.

What is a chemical contaminant?

Contaminants are chemical substances that have not been intentionally added to food or feed. These substances may be present in food as a result of the various stages of its production, processing, or transport. They also might result from environmental contamination.

What type of contaminant is bacteria?

Biological contamination is when bacteria or other harmful microorganisms contaminate food; it is a common cause of food poisoning and food spoilage.

What is a biological contamination?

Direct cross-contamination – allowing raw food that has food poisoning bacteria on it to touch cooked or ready to eat food.
Indirect cross-contamination – where something helps the organisms move from one place to another.

What is the difference between contamination and cross contamination?

Contamination is the presence of substances and conditions in food that can be harmful to humans. Cross contamination is the transfer of biological, physical or chemical contaminants to food products from raw foods, food handlers, and food processing equipment.
