What are the 4 main types of food contamination?
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.
Which of the following is an example of direct cross infection?
Direct contact infections spread when disease-causing microorganisms pass from the infected person to the healthy person via direct physical contact with blood or body fluids. Examples of direct contact are touching, kissing, sexual contact, contact with oral secretions, or contact with body lesions.

There are four main routes to food contamination: cross-contamination, improper hand washing, inappropriate storage and temperatures, and contamination by animal waste. Cross-contamination is the transference of harmful bacteria from one source to another.
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 is cross contamination food?
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. Minnesota Department of Health Consumer Fact Sheet.

Failing to wash your hands after handling nuts. Using a knife to spread peanut butter, not cleaning it properly, and then using it to spread jam.
What are some examples of indirect contact?
Indirect contact
- Airborne transmission. Some infectious agents can travel long distances and remain suspended in the air for an extended period of time.
- Contaminated objects.
- Food and drinking water.
- Animal-to-person contact.
- Animal reservoirs.
- Insect bites (vector-borne disease)
- Environmental reservoirs.
What is cross contamination example?
People can also be a source of cross- contamination to foods. Some examples are: Touching raw meats then handling vegetables or other ready-to-eat foods without washing hands between tasks. Using a food soiled apron or towel to wipe your hands between handling different foods.
What are direct contact diseases?
These are diseases caused by microorganisms that are spread by person-to-person contact or indirect contact with contaminated objects.
What is direct and indirect contact?
Direct contact transmission involves immediate contact between two people (or with an animal). Indirect contact transmission involves an object that becomes contaminated by touch then spreads the infection by touch.
Which of the following is an example of direct contact?
Examples of direct contact are touching, kissing, sexual contact, contact with oral secretions, or contact with body lesions.
What are the 4 types of diseases? There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic diseases and non-genetic hereditary diseases), and physiological diseases.
What type of diseases is caused by the direct and indirect spread of pathogens? Communicable (also known as infectious or transmissible) diseases are caused by microorganisms such as bacteria, viruses, parasites and fungi that can be spread, directly or indirectly, from one person to another.
Is food poisoning direct or indirect contact?
Cross-contamination may occur when raw contaminated food comes in contact with other foods, especially cooked foods, through direct contact or indirect contact on food preparation surfaces.
Is droplet infection direct or indirect?
Droplet spread is classified as direct because transmission is by direct spray over a few feet, before the droplets fall to the ground. Pertussis and meningococcal infection are examples of diseases transmitted from an infectious patient to a susceptible host by droplet spread.
What is an example of cross contamination?
People can also be a source of cross- contamination to foods. Some examples are: Touching raw meats then handling vegetables or other ready-to-eat foods without washing hands between tasks. Using a food soiled apron or towel to wipe your hands between handling different foods.
What is direct transmission?
In direct transmission, an infectious agent is transferred from a reservoir to a susceptible host by direct contact or droplet spread. Direct contact occurs through skin-to-skin contact, kissing, and sexual intercourse. Direct contact also refers to contact with soil or vegetation harboring infectious organisms.
How can direct contamination be prevented?
Keep it clean:
- Wash hands and surfaces often.
- Wash hands with soap and hot water before and after handling food, and after using the bathroom, changing diapers; or handling pets.
- Use hot, soapy water and paper towels or clean cloths to wipe up kitchen surfaces or spills.

- 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.
What are the 3 major causes of food contamination give an example for each? 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.
