Foodborne illnesses arise from the consumption of foods affected by biological contamination. The most common examples of biological contamination include bacteria, viruses, parasites, and fungi.

What are the 4 types of biological contamination?
The Four Types of Contamination 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 the three factors of biological contaminants?
Temperature, relative humidity, sources of nu- trients, and air movement affect the growth and dissemination of biological contaminants. Many organisms grow independent of other living or- ganisms, including the great majority of bacteria and fungi.
What is an example of a biological contaminant?
Biological contaminants include bacteria, viruses, animal dander and cat saliva, house dust, mites, cockroaches, and pollen. There are many sources of these pollutants. By controlling the relative humidity level in a home, the growth of some sources of biologicals can be minimized.
What is a biological contamination?
BIOLOGICAL CONTAMINATION. Biological contamination occurs when food becomes contaminated by living organisms or the substances they produce. This includes biological matter produced by humans, rodents, insects and microorganisms.
What is an example of biological contamination in food?
The biological contamination of food is commonly the result of fecal contamination of our food. Examples of biological contaminants and the problems they cause include: Bacteria, like Salmonella, which will lead to nausea, vomiting, and diarrhea. Viruses, such as rotavirus, which will lead to the stomach flu.
What is biological contamination in food?
Briefly, biological contamination is when food is contaminated with infectious bacteria (such as Salmonella spp. and L. monocytogenes) or toxin-producing organisms (such as Clostridium botulinum) and viruses (such as norovirus), which are a common cause of food poisoning and food spoilage.
What are the 3 types of contamination?
There are three different types of food contamination – chemical, physical and biological. All foods are at risk of becoming contaminated, which increases the chance of the food making someone sick.
Which is a biological contaminant quizlet?
There are four types of microorganisms that can contaminate food and cause foodborne illness: bacteria, viruses, parasites, and fungi.
What are the types of contamination?
The three types of contamination are biological, physical, and chemical. However, for the purpose of this article, we will discuss four categories. These include chemical contamination, physical contamination, microbial contamination, and allergen contamination.
What are biological contaminants in water?
Biological contaminants are organisms in water. They are also referred to as microbes or microbiological contaminants. Examples of biological or microbial contaminants include bacteria, viruses, protozoa, and parasites.
Is human hair biological contamination?
Hair is a source of microbiological contamination as the human scalp often contains Staphylococcus Aureus, a food poisoning organism. Therefore any hair in food can be a root cause of cross contamination and can indeed make us ill.
What are 5 biological food hazards?
Examples of biological hazards are: disease-causing bacteria, viruses, parasites, molds, yeasts, and naturally occurring toxins.
Which of the following is a contaminant?
(b) is the following can be called contaminant . Particulate matter (PM) pollution is caused by these particles. Small particles can go deep into the lungs and cause health issues if there are enough of them.
What are physical contaminants?
Typical physical contaminants found in food include jewellery, plastic, bones, stones, hair, pest remains, and fabrics. Along with that, problems with the food premises or equipment, such as flaking paint or loose screws can be a source of physical contamination.
What are the 10 food contamination sources?
Major contamination sources are water, air, dust, equipment, sewage, insects, rodents, and employees. Contamination of raw materials can also occur from the soil, sewage, live animals, external surface, and the internal organs of meat animals.
What are 3 ways food can be contaminated?
There are three types of food contamination: biological, chemical and physical contamination. Learn how they occur, and ways to prevent them.
How do biological contaminants lead to foodborne illness?
Food-borne diseases can be caused consuming food or water contaminated by pathogenic microorganisms such as bacteria and their toxins, fungi, viruses, and parasites. Food can be contaminated both at the source as raw material, and during food processing up to storage and distribution.
Which is a biological contaminant Servsafe?
Contaminants. Here are the three types of contaminants: Biological: Examples include bacteria, viruses, parasites, fungi, and toxins from plants, mushrooms, and seafood. Physical: Examples include foreign objects such as dirt, broken glass, metal staples, and bones.
Which is a biological contaminant quizlet Servsafe?
Biological contaminants include mould, house dust, bacteria, viruses, animal dander, cat saliva, pollen, cockroaches and mites.
Which is an example of a physical contaminant quizlet?
What are two examples of a physical contaminant? Two examples of a physical contaminant are cherry pits and fish bones.
What are 5 physical contaminants?
Common examples of physical contaminants include hair, bandages, fingernails, jewelry, broken glass, metal, paint flakes, bone, the body parts of pests, or pest droppings.
What is contamination example?
Chemical contamination. Examples: vapor, gasses, moisture, molecules. Biological contamination. Examples: fungus, bacteria, virus.
What are the 5 main contaminants of water?
- Nitrates.
- Arsenic.
- Microorganisms, Bacteria, and Viruses.
- Aluminum.
- Fluoride.

What causes biological pollution?
There are many sources of these pollutants. Pollens originate from plants; viruses are transmitted by people and animals; bacteria are carried by people, animals, and soil and plant debris; and household pets are sources of saliva and animal dander.
