Harmful microorganisms in food used daily

Type of microorganisms

Characteristic

Food sources are susceptible to contamination

S. typhimurium, S.enteritidis

Symptoms of infection: fever, diarrhea, abdominal cramps, headache, lasting 4 to 7 days.
The endotoxins of Salmonella bacteria cause very bad effects in the intestine, the endotoxins will damage the intestinal lining (irritation of the intestines causing abdominal pain, bleeding, or possibly perforation).
The endotoxin released by Salmonella bacteria goes into the bloodstream to the central nervous system, causing nervous system damage and systemic toxicity.

Raw poultry, eggs, beef, vegetables, fruits, dairy products

Bacillus cereus

This type of bacteria is abundant and is the leading cause of food poisoning. Symptoms of Bacillus cereus poisoning are abdominal pain, diarrhea, or vomiting about 15 to 30 minutes after eating food contaminated with this bacteria.

Rice, cereals, beans, spices

Campylobacter jejuni

Most people with this infection will have diarrhea, cramps, stomach pain, and fever for 2 to 5 days. In more severe cases, bloody diarrhea may be accompanied by nausea and vomiting.

Campylobacter bacteria are very dangerous for young children, the elderly and people with weakened immune systems

Milk, pork, livestock products, water

Listeria monocytogenes

Bacteria do not secrete exotoxins, but endotoxins cause necrosis. Pathogenicity of Listeria monocytogenes:

Bacteria after entering the body if through the digestive tract: Can cause diseases in the gastrointestinal tract or not only cause diseases in the gastrointestinal tract but also can enter the bloodstream causing bacteremia or spread to The central nervous system causes meningitis, a serious illness that is common in people with weakened immune systems.

In pregnant women, the disease can be transmitted to the fetus, causing miscarriage, stillbirth, premature birth, or neonatal sepsis, meningitis 1 to 4 weeks after birth.

Meat products, especially pork, milk, exist widely in the wild in soil, manure, animals, spoiled vegetables, sewage, milk, cheese, and some canned animal foods not hygienic

Escherichia coli 

Some types cause diarrhea and all can cause infections

E. Coli O157:H7 can cause gastrointestinal bleeding, kidney failure, even death.

Undercooked beef, untreated milk and juices, contaminated water.

Clostridium botulinum

C. botulinum has the ability to produce toxins in food, cause botulism.., produce botulinum toxin. This is a very powerful toxin that quickly penetrates the intestinal mucosa to the peripheral nervous system, causing paralysis of the whole body and a very high mortality rate.

Canned foods that have not been properly handled contain  C. botulinum spores.

Clostridium perfringens

In the gastrointestinal tract, C. perfringens produces toxins that act on the small intestine. Only  C. perfringens type A has been precisely identified in association with this food poisoning syndrome that causes gastroenteritis, watery diarrhea, and abdominal pain.

Beef, poultry meat; meat sauce, and food dry or
processed food

Mildew

Certain types of Mildew, including yeast, can be harmful to human health. They produce toxic metabolites called mycotoxins.

Ingestion or inhalation of large numbers of Mildew can lead to allergic reactions and respiratory problems. When the body has an allergic reaction, there will be symptoms such as: watery eyes, itchy eyes, chronic joint pain, headache or migraine, difficulty breathing, fatigue, rash, sinusitis, nasal congestion, and sneezing It happens quite often

Soil, water, air, food

Norovirus

Norovirus is found in contaminated food or drink. They can live on surfaces and spread through contact with an infected person.

Symptoms of infection that can last for several days include nausea, stomach cramps, vomiting, diarrhea, headache, fever, and fatigue.

Contaminated food

Vibrio parahaemolyticus

Vibrio parahaemolyticus bacteria live in saltwater, often found in seafood. People who like to eat raw, undercooked seafood will be susceptible to this infection.

Within 24 hours, infected people will have symptoms of watery diarrhea, abdominal cramps, nausea, vomiting, fever and cold.
