Examples of substances or organisms that can make food unfit for human consumption are insects, pests, dust, or biocides. “Food contaminants are any harmful substances unintentionally added to food, which may be chemicals from natural sources, environmental pollution, or formed during food processing.”
Food contamination refers to the presence of harmful chemicals and microorganisms in food, which can cause consumer illness. This article addresses the chemical contamination of foods, as opposed to microbiological contamination, which can be found under foodborne illness.
Beside above, what are the three main types of food contamination? While there are many food safety hazards that can cause food contamination, most fall into one of three categories: biological, physical or chemical contamination. It’s important to understand what the potential hazards are when it comes to food, especially if you are preparing or serving food for someone else.
Likewise, what are the 4 types of food contaminant?
There are four main types of contamination: chemical, microbial, physical, and allergenic. All food is at risk of contamination from these four types.

What are sources of food contamination?
Food products are rich in nutrients required by microorganisms and may become contaminated. Major contamination sources are water, air, dust, equipment, sewage, insects, rodents, and employees.
What are the major causes of food contamination?
There are three ways that food can be contaminated: biological hazards (microorganisms) including bacteria, fungi, yeasts, mould and viruses. chemical hazards. including cleaning chemicals or foods with naturally occurring toxins, such as green potatoes. physical hazards.

How does contamination happen?
Food contamination occurs when a microbial or environmental contaminant enters food (microbial being more common). Microbial contaminants include bacteria, mold, fungi, viruses, or their toxins/by-products. Environmental contaminants include pesticides, heavy metals, and other chemicals.
How does food become unsafe?
Food can be contaminated when a person who is preparing the food has not washed his/her hands.

But if the food has been at room temperature for more than two hours, bacteria may have accumulated to dangerous levels and formed heat-resistant toxins that cannot be killed by cooking.
What are contamination hazards of food?
Food safety hazards occur when food is exposed to hazardous agents which result in contamination of that food. Food hazards may be biological, chemical, physical, allergenic, nutritional and/or biotechnology-related.
What is a high risk food?
Foods that are ready to eat, foods that don’t need any further cooking, and foods that provide a place for bacteria to live, grow and thrive are described as high-risk foods. Examples of high-risk foods include: cooked meat and fish. gravy, stock, sauces and soup. shellfish.
