What Causes Milk Food Poisoning?
Milk can become contaminated with harmful bacteria such as Salmonella, Listeria, E. coli, and Campylobacter. These pathogens can enter milk through improper handling, storage, or pasteurization failures.

| Campylobacter | Raw or undercooked milk | Diarrhea, cramping, fever |
How Soon Do Symptoms Appear?
The onset of symptoms varies depending on the bacteria involved:
- Salmonella: Symptoms typically appear 6 to 72 hours after ingestion.
