Clean, separate, cook, chill — four kitchen habits that lower the chance of food poisoning.
Transcript & sources → All videosMr. Age is AgeGen's editorial character. Facts come from the protocol above.
The protocol
- Clean: wash hands for at least 20 seconds with soap and water before, during and after preparing food; wash utensils, cutting boards and counters with hot soapy water after each food item.
- Separate: use one cutting board or plate for raw meat, poultry and seafood and another for produce, bread and foods that will not be cooked.
- Cook: cook food to the safe internal temperature for that food, using a food thermometer, so that germs are killed.
- Chill: refrigerate perishable food and cooked leftovers within 2 hours, or within 1 hour if it has been above 90 °F (32 °C), for example in a hot car or at a picnic.
- Duration: ongoing.
What you get
- Separating raw and ready-to-eat foods prevents cross-contamination with harmful germs.
- Cooking to a safe temperature kills germs that can make you sick.
- Prompt chilling slows the growth of germs on perishable food.
Contraindications
- People aged 65 and older, children under 5, people with weakened immune systems and pregnant women are at higher risk of food poisoning — follow the CDC's safer food choices guidance for their group and ask a clinician about specific foods to avoid.
- Severe or lasting vomiting, diarrhoea or fever after a meal needs medical advice.
Evidence level
High. Clean, separate, cook and chill are the CDC's four steps to food safety, and the CDC's risk-factor page names the groups for whom getting them right matters most.
