Causes Food contamination is usually caused by bacteria, but it can also sometimes be caused by viruses or parasites. Some of the main sources of contamination are described below. Campylobacter. In the UK, campylobacter bacteria are the most common cause of food poisoning.The bacteria are usually found on raw or undercooked meat (particularly poultry), unpasteurised milk and untreated water.n young children, the rotavirus is a common cause of infection from contaminated food. The symptoms usually develop within a week and pass in around five to seven days. Parasites. In the UK, food poisoning caused by parasites is rare.

- These conditions may be caused by the result of the dysbiosis rather than being a direct effect. The causes of dysbiosis. The most common cause of dysbiosis – and the reason why it is so common in the west – is the inappropriate use of antibiotics. Viral illnesses are commonly and immediately treated with antibiotics, but this is usually ineffective.

Microorganisms, Bacteria and Viruses Microorganisms, Bacteria and Viruses. Microbiological contamination of water has long been a concern to the public. From the 1920's-1960's, the bacillus which causes typhoid fever was considered a major problem in the water supply (1).oliforms will be one of the first bacteria present in the water should contamination occur, and they will be in much larger quantities than some pathogenic microbes that may be present. Therefore, coliforms act as indicators of possible contamination.

Coliform Bacteria Coliform bacteria are often referred to as “indicator organisms” because they indicate the potential presence of disease-causing bacteria in water. The presence of coliform bacteria in water does not guarantee that drinking the water will cause an illness.Rather, their presence indicates that a contamination pathway exists between a source of bacteria (surface water, septic system, animal waste, etc.) and the water supply.he presence of coliform bacteria in water does not guarantee that drinking the water will cause an illness.

Protecting Your Well From Contamination Often the biggest contamination threats are things in your own backyard. The following are examples of potential problems and some ways to prevent them. Poor Well Construction. The fastest way to contaminate groundwater is through a well. A well provides a direct path for contamination to travel from the surface to the aquifer. An inadequate well casing or annular seal may allow surface water or contaminated groundwater to seep along the outside of the casing and enter your well (see Figure 1, Annulus or Casing Seal).

Differentiate between the major types of foodborne diseases -- infection, intoxication, and toxin-mediated infection. An intoxication results when a person eats food containing toxins that cause illness. Toxins are produced by harmful microorganisms, the result of a chemical contamination, or are naturally part of a plant or seafood.Some bacteria cause an intoxication. Viruses and parasites do not cause foodborne intoxication.The foodborne bacteria that cause intoxication are: Clostridium botulinum, Staphylococcus aureus, Clostridium perfringens, and Bacillus cereus.ome bacteria cause an intoxication.
