1. Gastrointestinal food poisoning
Gastrointestinal food poisoning is more common in summer and autumn when the temperature is high and bacteria are easy to grow and multiply in food. It is mainly characterized by acute gastroenteritis symptoms 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 its enterotoxin. The common foods that cause food poisoning caused by staphylococcus are starch (such as leftovers, porridge, rice flour, etc.), milk and dairy products, fish, eggs, etc. When the contaminated food is left at room temperature of 20 ~ 22℃ for more than 5 hours, the bacteria multiply in large numbers and produce enterotoxin, which has strong heat resistance and can still maintain its virulence after being heated and boiled for 30 minutes. The disease is more common in summer and autumn.
3. Vibrio parahaemolyticus food poisoning
It is an acute and subacute disease caused by eating food contaminated by Vibrio parahaemolyticus or food containing the bacteria. Vibrio parahaemolyticus is a common pathogen of food poisoning, accounting for a considerable proportion of bacterial food poisoning. Clinically, gastrointestinal symptoms, such as nausea, vomiting, abdominal pain, diarrhea and watery stool, are the main symptoms. The food poisoning caused by this bacterium has the common characteristics of bacterial food poisoning, such as outbreak onset (same time, same area, same or similar symptoms, same contaminated food), short incubation period (several hours to several days) and certain seasonality (summer and autumn).
4. Proteus food poisoning
It is caused by ingesting a large amount of food contaminated by Proteus, which belongs to food poisoning caused by conditional pathogenic bacteria. Proteus is a gram-negative bacterium, which can be divided into Proteus vulgaris and Proteus mirabilis according to different biochemical reactions, with more than 100 serotypes. A large number of Proteus grow and multiply in human body, and produce enterotoxin, which leads to food poisoning. The incidence rate is high in summer and autumn, and the clinical manifestations are gastrointestinal type and allergic type.
