How Long Does Food Poisoning Last?

Food poisoning usually lasts from a few hours to several days, although some infections can continue for a week or longer. The duration depends on the organism or toxin involved, how much contaminated food was consumed, and the person’s overall health. Common symptoms include vomiting, diarrhea, nausea, abdominal cramps, and fever. Severe cases can lead to dehydration and other complications.

If you suspect contaminated food from a restaurant, caterer, store, or manufacturer, preserve any evidence that may support your claim. This can include receipts, food packaging, photographs, and medical records. Laboratory testing and public health investigations may help identify the pathogen and trace the source of contamination.

For a legal claim, getting sick after eating a particular food is generally not enough on its own. The available evidence must support a connection between the contaminated food and the illness and, depending on the circumstances, establish that the food was supplied or handled by the party responsible for the contamination. If symptoms are severe or persist, seek medical attention and keep records of your diagnosis and treatment.
