01Short answer

The basis is the WHO five keys: keep clean, separate raw and cooked, cook thoroughly, keep food at safe temperatures, use safe water and raw materials. Special care in the United Kingdom: unpasteurised cheeses, chilled pâtés, ready-made sandwiches and salads, and raw or undercooked shellfish. During neutropenia choose freshly cooked hot food, pasteurised dairy and safe water.

02Simple explanation

Clean hands and kitchen.

Raw and cooked apart, meat cooked through.

Chill quickly.

03Scientific explanation

Five keys: the WHO “Five Keys to Safer Food” sets out five core rules against food-borne illness.

In cancer: The US FDA advises people with cancer to avoid raw or undercooked meat, raw eggs, unpasteurised milk and soft cheeses, and raw sprouts.

04What happens in the body?

Shopping

Buy meat and dairy where there is refrigeration; check packaging and use-by dates. Pick up chilled items last and get them home quickly.

In the kitchen

A separate board and knife for raw meat. Cook meat, poultry and eggs thoroughly. Wash fruit and vegetables in safe water.
