In general, mild food poisoning can recover on its own. The causative agents of food poisoning and their toxins are the main pathogenic factors, among which the common causative agents are Vibrio parahaemolyticus, Salmonella and Staphylococcus aureus. In mild food poisoning, toxins and pathogenic bacteria can be gradually excreted from the body under self-protective mechanisms such as vomiting and diarrhea, which can lead to self-healing. It can also be combined with hydration and high-protein foods to promote the decomposition of toxins. If the food poisoning is serious or a cluster of food poisoning, it is necessary to go to the emergency department of the hospital for vomiting, drainage, rehydration, and even gastric lavage treatment. Next, the discharge will be tested for bacterial food poisoning at the primary CDC to clarify the cause of poisoning and provide a basis for effective treatment through microbiological testing. Usually, you should pay attention to drink more water, eat healthy and reasonable diet, and avoid eating unclean food.
