What to Do After Food Poisoning in California
A serious foodborne illness is miserable, and in the middle of it the last thing on your mind is evidence. But a few steps, when you are able, can preserve the proof of the source. Here is a clear order of operations.
Get care and ask for a stool test
See a doctor for a serious illness and ask for a stool test to confirm the pathogen. A lab-confirmed diagnosis is powerful proof of the source, and it guides your treatment.
Save the food, packaging, and receipts
If you can, keep any leftover food and its packaging (with the lot number), and receipts showing where you ate or shopped. Refrigerate or freeze the food. These help, but a claim does not depend on them.
Report it to the health department
Reporting the illness creates an official record and can trigger or add to an investigation — which helps establish the source and may reveal an outbreak.
Note what and when you ate
Write down what you ate and when in the days before. The timing of symptoms is central to identifying the source, because different bugs strike on different timelines.
Get advice while the evidence is fresh
The strongest proof is available early. A free, confidential conversation soon can help preserve it and explain whether you have a claim.
Frequently asked questions
Is it too late if I already recovered and kept nothing?
Often not. A claim does not depend on saved food — your medical records, any lab confirmation, receipts, symptom timing, and any related recall or outbreak can still establish the source. It is worth a review even after the fact.
