It is divided into four types: gastrointestinal food poisoning, staphylococcal food poisoning, Vibrio parahaemolyticus food poisoning, and Proteus food poisoning.

1. Stomach Intestinal food poisoning
Gastrointestinal food poisoning is more common in summer and autumn when temperatures are higher and bacteria tend to grow and multiply in food. It is mainly characterized by symptoms of acute gastroenteritis such as nausea, vomiting, abdominal pain, and diarrhea. .
2. Staphylococcal food poisoning
It is an acute disease caused by eating food contaminated by Staphylococcus aureus and the enterotoxin it produces. Common foods that cause Staphylococcus aureus food poisoning mainly include starch (such as leftover rice, porridge, rice noodles, etc.), milk and dairy products, fish, eggs, etc. When contaminated food is left at room temperature of 20 to 22°C for more than 5 hours , the bacteria multiply in large numbers and produce enterotoxin. This toxin is very heat-resistant and can still maintain its virulence and cause disease after being heated and boiled for 30 minutes. The disease is most common in summer and autumn.
3. Vibrio parahaemolyticus food poisoning
It is an acute, sub-toxic disease that occurs after eating food contaminated by Vibrio parahaemolyticus or eating food containing this bacteria. acute illness. Vibrio parahaemolyticus is a common food poisoning pathogen and accounts for a large proportion of bacterial food poisoning. Clinically, gastrointestinal symptoms such as nausea, vomiting, abdominal pain, diarrhea and watery stools are the main symptoms. Food poisoning caused by this bacterium has the characteristics of outbreak onset (same time, same area, same or similar symptoms, same contaminated food), short incubation period (hours to days), and certain seasonality (mostly summer and autumn). Common features of poisoning.
4. Proteus food poisoning
It is caused by ingesting a large amount of food contaminated by Proteus and is a food poisoning caused by opportunistic pathogenic bacteria. Proteus is a gram-negative bacillus. It can be divided into Proteus vulgaris and Proteus mirabilis based on different biochemical reactions. There are more than 100 serotypes. A large number of Proteus bacteria grow and multiply in the human body and produce enterotoxin, causing food poisoning. The incidence rate is higher in summer and autumn, and the clinical manifestations are gastrointestinal type and allergic type.
