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 are biological contaminants in food?
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 are the 4 biological 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 main types of biological contamination?
Biological contaminants include bacteria, molds, mildew, viruses, animal dander and cat saliva, house dust, mites, cockroaches, and pollen (see more about Asthma triggers at www.epa.gov/asthma).
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.
What are the three types of food 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.
What are 5 biological food hazards?
Examples of biological hazards are: disease-causing bacteria, viruses, parasites, molds, yeasts, and naturally occurring toxins.
What are 5 ways food can be contaminated?
Main routes to contamination There are four main routes to food contamination: cross-contamination, improper hand washing, inappropriate storage and temperatures, and contamination by animal waste.
What is an example of a biological hazard which can cause foodborne illness?
Bacteria, viruses, and parasites, are the main biological hazards causing acute foodborne diseases. Certain biological toxins can also be considered as causing acute effects, such as most seafood toxins, and these are discussed separately in another overview on chemical hazards.
What are the 3 main types of contamination?
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. Chemical: Examples include cleaners, sanitizers, and polishes.
Is salmonella a biological contamination?
Under the Animal Food Contaminants program, biological hazards that are routinely monitored include Salmonella, Listeria monocytogenes, and pathogenic Escherichia coli bacteria.
What are the main sources of food contamination?
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 the 4 types of food spoilage?
- 1 Microbial spoilage. Microbial spoilage is caused by microorganisms like fungi (moulds, yeasts) and bacteria.
- 2 Physical spoilage.
- 3 Chemical spoilage.
- 4 Appearance of spoiled food.
How do biological contaminants lead to food borne 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.
What are some examples of physical contamination?
Some of the more common examples of physical contaminants include glass, metal, rubber, bone, wood, stone and plastic. Here’s a closer look at how some of those contaminants find their way into food products.
What is an example of a chemical contaminant?
Chemical contaminants are elements or compounds. These contaminants may be naturally occurring or man-made. Examples of chemical contaminants include nitrogen, bleach, salts, pesticides, metals, toxins produced by bacteria, and human or animal drugs. Biological contaminants are organisms in water.
What can cause biological food spoilage?
Various factors cause food spoilage, making items unsuitable for consumption. Light, oxygen, heat, humidity, temperature and spoilage bacteria can all affect both safety and quality of perishable foods.
What 4 biological pathogens microorganisms can make your food unsafe to eat?
- Norovirus.
- Salmonella.
- Clostridium perfringens.
- Campylobacter.
- Staphylococcus aureus (Staph)
What is an example of a biological hazard in food quizlet?
May be a biological hazard, such as a fungus that causes a foodborne illness. Multi-celled organisms that can cause illness when eaten; roundworms are an example potential biological hazards. Disease-causing organisms, such as bacteria, viruses, parasites or fungi.
What is an example of a biological hazard quizlet?
Biological hazards—a living or once-living organism, such as a virus, a mosquito, or a snake, that poses a threat to human health.
Which of the following could be sources of biological hazards?
Sources of biological hazards may include bacteria, viruses, insects, plants, birds, animals, and humans. These sources can cause a variety of health effects ranging from skin irritation and allergies to infections (e.g., tuberculosis, AIDS), cancer and so on.
What is the best example of physical contamination?
Examples of Physical Contamination 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 food causes Salmonella?
You can get a Salmonella infection from a variety of foods, including chicken, turkey, beef, pork, eggs, fruits, sprouts, other vegetables, and even processed foods, such as nut butters, frozen pot pies, chicken nuggets, and stuffed chicken entrees.
Can Salmonella be killed by cooking?
Does cooking kill salmonella? Thorough cooking can kill salmonella. But when health officials warn people not to eat potentially contaminated food, or when a food is recalled because of salmonella risk, that means don’t eat that food, cooked or not, rinsed or not.
What bacteria causes Salmonella?
Salmonella infection is caused by a group of salmonella bacteria called Salmonella. The bacteria are passed from feces of people or animals to other people or animals. Contaminated foods are often animal in origin. They include beef, poultry, seafood, milk, or eggs.
