It is generally not recommended to continue to consume snails that have been left at room temperature overnight. However, if snails are stored in the refrigerator, they are generally edible the next day after being heated. Snails belong to the snail family and are edible animals, which contain more nutrients such as proteins, sugars, fats and other nutrients, and have a more delicious flavor. Each 100 grams of snail contains 59 calories, 6 grams of carbohydrates, 7.5 grams of protein, 86 milligrams of cholesterol, 156 milligrams of calcium, 1.4 milligrams of iron, and 17 micrograms of selenium. Since snails may contain pathogenic bacteria, it is necessary to cook them thoroughly during food preparation to avoid the emergence of diseases caused by ingesting pathogenic bacteria themselves. If cooked or dead snails are stored at room temperature, the bacteria contained therein may multiply, and if they are consumed again after one night, they may cause gastrointestinal symptoms such as vomiting and diarrhea. However, if the snail is stored in a cold environment such as a refrigerator, the bacteria proliferation rate is slower, and it is generally considered acceptable to consume the snail after heating it up on the second day. If gastrointestinal symptoms occur after consuming snails, one should consult the relevant doctor for medical treatment.
