Simple steps to cut your risk of foodborne illness at home

A Lancet study estimates 1.5 million deaths worldwide from foodborne illnesses in 2021, with Salmonella, E. coli, norovirus and Listeria as major culprits. The article offers practical home precautions: refrigerate perishable foods within two hours, avoid undercooked meat and unpasteurized dairy, wash produce, keep cooked foods separate, and stay hydrated if illness occurs. A balanced diet and healthy lifestyle support immunity, and vulnerable groups—children, the elderly, and immunocompromised individuals—face higher risk. Global food-safety systems vary, so personal kitchen hygiene matters greatly.
