Food poisoning or food intoxication is an acute condition that occurs after ingestion of food. In these poisoning causes disease penetrates the body through food and manifestations of poisoning began soon after meals. Poisoning may be of biological and non-biological origin.
The infection is caused by bacteria and their toxins. They enter the body through the consumption of food in which pre- multiplied bacteria. Violation of basic hygiene and improper food storage are conducive factors (enablers) for contamination of food. Toxins of certain microbes such as staphylococci are resistant to boiling and digestion, which means that the risk of poisoning is high, even in the heat treatment. The most common culprits in food poisoning are unwashed fruits and vegetables, and spoiled food.
The most common types of food poisoning are divided into three major groups. The first group are microbial intoxications / food toxicoinfections /, the second group are poisoning related to consumption of poisonous plants, the latter group includes intoxication from poisonous chemicals. The most common food poisoning are microbial intoxications. These poisoning are associated with the consumption of foods that are contaminated with pathogenic microorganisms and their toxins.
Types of microbial intoxicationsThe main source of microbial intoxication is well known salmonella. Transmitted by meat, milk, eggs from diseased birds and secondarily contaminated products, bacterium spreads quickly and is very stable. Staph infection is obtained from the formed staphylococcal enterotoxin. Main sources of this infection are humans / through the skin and nasopharynx / and mastitis sick animals - they contaminate milk and thus many dairy and confectionery products.
Kolienterit - contamination of food products with coliform is mostly human - through contaminated hands and food. Poisoning can happen after eating foods that are not stored in the refrigerator. These are for example, meat, egg and fish products. The type and flavor of the food is not changed, by the coliforms.
Botulism is the worst food poisoning. These cases are often fatal. Cause of botulism is organism that forms spores and develop in a low oxygen environment - canned vegetables, sausages, and fish. Commonly found in soil where it falls on the food through unwashed vegetables. It is believed that botulinum toxin is the most potent natural toxins. Usually the food is kind of rotten, but it is possible that there are no visual changes and the food still be infected.
