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.

There are four main types of contamination: chemical, microbial, physical, and allergenic. All food is at risk of contamination from these four types. This is why food handlers have a legal responsibility to ensure that the food they prepare is free from these contaminants and safe for the consumer.

Moreover, What are the 4 sources of biological contamination?

Biological contaminants include bacteria, viruses, fungi, protozoaprotozoaProtozoan, organism, usually single-celled and heterotrophic (using organic carbon as a source of energy), belonging to any of the major lineages of protists and, like most protists, typically microscopic. All protozoans are eukaryotes and therefore possess a “true,” or membrane-bound, nucleus.https://www.britannica.com › science › protozoanProtozoan | microorganism | Britannica, insects (fleas and cockroachescockroachesThe cockroach is characterized by a flattened oval body, long threadlike antennae, and a shining black or brown leathery integument. The head is bent downward, and the mouthparts point backward instead of forward or downward as is the case in most other insects.https://www.britannica.com › animal › cockroach-insectcockroach | Definition, Facts, & Species | Britannica), and arachnidsarachnids: any of a class (Arachnida) of arthropods comprising chiefly terrestrial invertebrates, including the spiders, scorpions, mites, and ticks, and having a segmented body divided into two regions of which the anterior bears four pairs of legs but no antennae.https://www.merriam-webster.com › dictionary › arachnidArachnid | Definition of Arachnid by Merriam-Webster (dust mitesdust mitesDust mites are microscopic bugs that live in household dust. Many people with asthma are allergic to dust – but it’s the droppings produced by the mites in the dust, along with the body fragments of dead dust mites, that really cause allergic reactions.https://kidshealth.org › parents › dust-mitesDefinition: Dust Mites (for Parents) – Nemours KidsHealth).

Secondly, What are the sources of biological contaminants?

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.

Simply so, What are the 3 types of cross contamination?

There are three main types of cross-contamination: food-to-food, equipment-to-food, and people-to-food.

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.

What are chemical food contaminants?

Chemical food contaminants are substances which are neither present naturally in the usual raw material used for food production nor are added during the regular production process. Furthermore, natural toxins form microorganisms or plants, and compounds formed during thermal treatment of food are of major interest.

Food hazards may be biological, chemical, physical, allergenic, nutritional and/or biotechnology-related. Hazards may be introduced into the food supply any time during harvesting, formulation and processing, packaging and labelling, transportation, storage, preparation, and serving.

What are chemical contaminants?

Chemical contaminants are chemicals toxic to plants and animals in waterways. The phrase ‘chemical contamination’ is used to indicate situations where chemicals are either present where they shouldn’t be, or are at higher concentrations than they would naturally have occurred.
