Accidentally eating something that has been gnawed by a rat should be closely monitored for its own condition, and clinical symptoms such as abdominal pain, fever, diarrhea, etc. should be sought immediately in a hospital.
Wild rats may carry a variety of bacteria and viruses, such as Hantavirus and Salmonella typhimurium. Rat urine, droppings and other secretions from rats may remain on the food that has been eaten by rats, and these secretions may contain the above bacteria, and therefore may cause discomfort after accidental human consumption.
If abdominal pain, vomiting or diarrhea occurs after consuming the food, it may be due to bacterial infection causing enteritis. If the symptoms are mild, drink plenty of water and take quinolones orally to fight infection; if the symptoms are serious, go to the hospital immediately for rehydration and anti-infective treatments to prevent dehydration or further aggravation of the condition.
If fever, chills, headache, etc. occur, it may be caused by viral infection (epidemic hemorrhagic fever), and should go to the hospital immediately for treatment.
