How can stool cultures help check for food poisoning?

ANSWER

Stool cultures are the most common lab test for food poisoning. Your doctor may order one if you have a fever or intense stomach pain along with other symptoms. She may also order one if you have symptoms that linger. A sample of your poop can help tell if your sickness is related to bacteria. It also can check for toxins, such as for botulism, which can be deadly. It can even reveal the germ’s DNA “fingerprint” and which antibiotics will kill it. Microscopic exams of stool can identify parasites. Stool tests aren’t always accurate, and they can take several days to come back.
