🛡️ Food safety during treatment
How to avoid foodborne infections when your immune system is weakened.
Foods that need caution during periods of neutropenia
Memorial Sloan Kettering and the Canadian Cancer Society recommend caution with: raw or undercooked meat (sushi, tartare, raw eggs), unpasteurised dairy (blue-veined cheeses, raw milk), unwashed fruit and vegetables, and bean or alfalfa sprouts. This does not mean you have to avoid all fresh foods, but that proper washing and cooking become essential.
Basic rules in the kitchen
Wash your hands with soap and water before preparing food and after handling raw meat. Wash all fruit and vegetables under running water, even those with a peel. Cook meat to safe temperatures: at least 74°C for poultry and 63°C for pork and beef. Keep cooked food in the fridge for a maximum of 3–4 days. Avoid food left at room temperature for more than 2 hours.
When to be more cautious
Not all cancer patients have the same risk of infection. The risk is higher during nadir periods (7–14 days after chemotherapy), in those with severe neutropenia (neutrophils below 500/mm³) and in those with a central venous catheter. Your doctor or nurse can tell you whether you are in a higher-risk period and whether you need to follow a low-contamination-risk eating plan.
