When making cans, if sterilization is not complete, bacteria will grow and multiply in the cans, producing toxins and gases. The gas will expand and cause the lid and bottom of the can to bulge. It is easy to get poisoned if you eat this kind of can. Most of the bacteria that cause poisoning are Clostridium botulinum, which produces a type of botulinum toxin that is highly toxic and can act on the human nervous system.

Symptoms:

In mild cases, dizziness, headache, fatigue, nausea and vomiting, blurred vision, drooping eyelids, in severe cases, unclear speech and enunciation, hoarse voice, difficulty in raising head, Difficulty chewing and swallowing, difficulty breathing, and even respiratory muscle paralysis and death.

Treatment measures:

If poisoning is found, vomiting should be induced immediately. Chopsticks, feathers, fingers, etc. can be used to stimulate the pharynx to induce vomiting. Then, clear water or light salt water can be taken orally, and then vomiting can be induced. Repeat this multiple times. Inducing vomiting can effectively prevent further absorption of residual toxins in the stomach. Due to the strong toxicity of botulinum toxin, the condition after poisoning will be serious, so after taking the above measures, you should be sent to the hospital for further treatment as soon as possible. The specific drug is botulinum antitoxin serum.

Notes:

In addition to cans with bulging lids, stinky tofu, ham, sausage and other foods can also have botulinum growth, so do not eat such expired or spoiled foods.
