Can cancer treatment make food poisoning more likely?
Yes, for some people. The National Cancer Institute explains that some cancer treatments lower the number of white blood cells that help your body fight infection. That can make it easier to get sick from contaminated food than it would be otherwise, which is why food safety steps matter more during treatment.
This risk is not the same all the way through. It can be higher at certain points in your treatment cycle, when white blood cell counts are especially low. So some people need to be more careful with food than others, and that can shift as treatment goes on.
The food safety steps NCI recommends can help lower the risk. Cook meat, fish, and eggs well. Keep hot foods hot and cold foods cold. Be careful with raw produce: pick items you can peel, or wash them very well.
If you notice signs of infection, call your care team right away, since an infection during treatment can be serious and needs quick attention. Your team can also tell you whether your own treatment raises your risk of foodborne illness, and what extra care, if any, makes sense for you.
