Meal prep hygiene 101

Keep a busy meal-prep session safe by separating raw food, cooling quickly and labelling every stored portion.
Preparing several meals at once creates convenience, but also more boards, containers and opportunities for raw food to meet ready-to-eat ingredients. Begin with clear surfaces, clean hands and enough containers before the kitchen becomes crowded.
Keep raw meat separate, wash equipment before using it for salad or cooked food, and refrigerate perishable dishes promptly. Keep the fridge at 5°C or below and label portions with the meal and date.
Plan what will be eaten first and what should be frozen. Safe meal prep is not an extra task after cooking; it is the final part of the recipe.

Boards, knives, and order of work

Prepare ready-to-eat vegetables before raw meat when possible. Use separate boards or wash the board and knife thoroughly with hot soapy water between tasks.
Colour coding can help, but a colour does not make a dirty board safe. Keep raw poultry juices away from salad and cooked food.
Replace deeply scored plastic boards - grooves harbour bacteria.
Run knives and tongs through the dishwasher or very hot water after raw meat contact.

Hands, cloths, and sinks

Wash hands with soap after handling raw meat, poultry or eggs and before touching handles, phones or spice jars. Clean contaminated surfaces promptly.
Use a fresh cloth or paper towel for raw-meat spills and launder tea towels regularly during a large prep session.

Cool quickly before the fridge

Divide large dishes into shallow containers so heat escapes quickly. Refrigerate within one to two hours rather than leaving food on the worktop for the afternoon.
Small warm portions can go into the fridge; avoid placing a very large steaming pot inside and raising the appliance temperature.
Set a cooling timer
Batch food can be forgotten while everyone eats. Portion it promptly and refrigerate within one to two hours, sooner in a very warm room.

Store and date correctly

Keep the fridge at 5 degrees C or below, label food and follow current storage guidance for the specific dish. Rice and other high-risk foods need particularly careful cooling.
Move older portions to the front and freeze food early when it will not be eaten in time.

Reheat once, hot throughout

Reheat food until steaming throughout, stirring microwave meals to remove cold spots. Follow current guidance on reheating frequency and the product instructions.
If a portion has warmed or spent too long out of the fridge, do not return it repeatedly for later.

Safe cooling, storage and reheating are part of batch cooking, not an optional final step. Use the batch-cook guide to plan portions and freezer destinations before starting.
