Food poisoning is a common and unpleasant condition caused by consuming contaminated food or beverages. The duration of food poisoning can vary depending on several factors, including the type of pathogen responsible, the individual's overall health, and the treatment received. Here's a general guideline for how long does food poisoning last:

Onset: Food poisoning symptoms usually appear within a few hours to a few days after consuming contaminated food. The onset can be rapid or gradual, depending on the causative agent.

Duration: In most cases, food poisoning symptoms last from a few hours to several days. Mild cases may resolve within a day or two, while more severe cases can persist for up to a week or longer.
