There are three main types of cross contamination: food-to-food, equipment-to-food, and people-to-food. In each type, bacteria are transferred from a contaminated source to uncontaminated food.
What are the 5 types of biological contaminants? Overview. Biological contaminants include bacteria, viruses, animal dander and cat saliva, house dust, mites, cockroaches, and pollen.
Similarly, What are chemical contaminants? 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 are chemical contaminants examples?
contaminated water, for example, dioxins, halogenated organic compounds or heavy metals. plant diseases – mycotoxins. contamination from weeds, for example, plant toxins. carry over of certain substances from animal feed.
What are biological contaminants in food?
Biology is the science of studying living beings such as bacteria, fungi, plants and animals and non-living being such as viruses. Biological contaminants of food are harmful and hazardous substances of biological origin in the food that can cause foodborne illness when they are consumed.
What are the 6 main sources of contamination in a kitchen?
Biological contamination is the leading cause of food-borne illness and food poisoning*, and a common cause of food spoilage and food waste. There are six types of microorganisms that can cause food-borne illness: bacteria, viruses, parasites, protozoa, fungi and prions.
What are toxic food contaminants? Food contaminants. Ensuring food safety and quality is a central public health concern. Food can be contaminated by toxic metals, pesticides and veterinary drug residues, as well as organic pollutants, radionuclides and mycotoxins.
What are the 5 types of chemical contaminants? Examples of chemical contaminants are:
- industrial chemicals.
- agricultural chemicals.
- toxic metals.
- preservatives.
- naturally occurring toxins.
What’s 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.

What does contaminant mean? Contaminants are defined as “substances (i.e. chemical elements and compounds) or groups of substances that are toxic, persistent and liable to bioaccumulate, and other substances or groups of substances which give rise to an equivalent level of concern”.
What are the two main types of contaminants in water?
Types of Drinking Water Contaminants
- Physical contaminants primarily impact the physical appearance or other physical properties of water. …
- Chemical contaminants are elements or compounds.
- Biological contaminants are organisms in water.
What are examples of physical contaminants?
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 are 3 ways to prevent physical contamination to food products? 5 Tips To Avoid Physical Contaminant Product Recalls

What are chemical contaminants in the food industry?
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.
What is Fattom in food safety? FATTOM is an acronym used to describe the conditions necessary for bacterial growth: Food, acidity, time, temperature, oxygen, and moisture. Foods provide a perfect environment for bacterial growth, due to their provision of nutrients, energy, and other components needed by the bacteria.
Why we should not eat contaminated food?
Chemical contamination can lead to acute poisoning or long-term diseases, such as cancer. Foodborne diseases may lead to long-lasting disability and death. Examples of unsafe food include uncooked foods of animal origin, fruits and vegetables contaminated with faeces, and raw shellfish containing marine biotoxins.
What is meat contamination? Most meat contamination is from the heavily colonized areas of the animal, such as the skin (fleece) and the gastrointestinal tract, and the type and numbers found will reflect both the animal’s indigenous microflora and its environment.
