Food poisoning symptoms? Let's talk about it

Food poisoning symptoms?

Gastrointestinal food poisoning is more common in summer and autumn when the temperature is high and bacteria are easy to grow in food. It is characterized by nausea, vomiting, abdominal pain, diarrhea and other symptoms of acute gastroenteritis.

It is an acute disease caused by eating food contaminated by Staphylococcus aureus and its enterotoxin. The common food causing staphylococcal food poisoning are starch (such as leftovers, porridge, rice noodles, etc.), milk and dairy products, fish, eggs, etc. when the contaminated food is stored at room temperature of 20-22 ℃ for more than 5 hours, the bacteria multiply in large quantities and produce enterotoxin. The toxin has strong heat resistance and can still maintain its virulence and cause disease after boiling for 30 minutes. Most of the disease occurred in summer and autumn.

It is due to eating food contaminated by Vibrio parahaemolyticus or eating food containing Vibrio parahaemolyticus. Vibrio parahaemolyticus is a common pathogen of food poisoning, which accounts for a large proportion of bacterial food poisoning. The main clinical symptoms are gastrointestinal symptoms, such as nausea, vomiting, abdominal pain, diarrhea and watery stool. The food poisoning caused by this bacterium has the common characteristics of outbreak onset (the same time, the same area, the same or similar symptoms, the same contaminated food), short incubation period (several hours to several days), and certain seasonality (summer and Autumn).

matters needing attention

If vomiting and abdominal pain are obvious, take propantheline or atropine subcutaneously or anisodamine. Those who can eat should be given oral rehydration. Severe vomiting or frequent diarrhea were given intravenous drip of sugar and saline. In case of acidosis, add 5% sodium bicarbonate injection or 11.2% sodium lactate solution as appropriate. The patients with severe dehydration or even shock should be actively rehydrated, electrolyte balance should be maintained and antishock treatment should be given.
