Preventing Cross-Contamination From Raw Meat and Poultry

Raw meat and poultry carry bacteria such as Salmonella, Campylobacter and E. coli that cause serious illness if they reach ready-to-eat food. Prevent cross-contamination by storing raw meat below and away from cooked and ready-to-eat items, using separate colour-coded boards and utensils, washing then sanitising surfaces and hands after every contact, and never letting raw juices drip onto other food. Key takeaways: Raw meat and poultry are the highest-risk foods in most kitchens; treat their juices as contaminated and keep them away from anything that will not be cooked again.. Store raw meat and poultry in sealed containers on the bottom shelf, below and separate from ready-to-eat food, at 5°C or colder.. Use separate, colour-coded boards, knives and utensils for raw meat, and never let them touch cooked or ready-to-eat food.. Clean then sanitise every surface, board and tool that has touched raw meat, and wash hands thoroughly straight afterwards.. Cooking poultry and meat to 75°C core is your final control, but it does not undo contamination that has already spread to ready-to-eat food.. Why raw meat and poultry are the highest risk Raw meat, and poultry in particular, routinely carry harmful bacteria including Salmonella, Campylobacter and certain strains of E. coli. These organisms live on and in the raw product and are only reliably destroyed by thorough cooking. Until that point, you must assume the meat, its packaging and any liquid it releases are all contaminated. Cross-contamination happens when those bacteria move from raw meat to food that will be eaten without further cooking, such as salads, sandwiches, garnishes, cooked meats or bread. The transfer can be direct, through contact, or indirect, through hands, boards, knives, cloths, containers or splashes. Even a smear of raw juice is enough to make a customer seriously ill. Because ready-to-eat food gets no cooking step to kill bacteria, keeping raw and ready-to-eat apart at every stage is the single most important habit in a safe kitchen. Store raw meat so juices never reach other food Store raw meat and poultry in clean, sealed, leak-proof containers so nothing can drip. Keep it on the bottom shelf of the fridge or coolroom, below and physically separated from cooked food, ready-to-eat food, fruit and vegetables. This way, if a container leaks, the liquid cannot fall onto food that will be eaten as is. Hold all of it at 5°C or colder. The temperature danger zone is 5°C to 60°C, where bacteria multiply quickly, so minimise the time raw meat spends out of refrigeration during deliveries, portioning and prep. Bottom shelf, always below ready-to-eat and cooked food. Sealed, leak-proof containers, never open trays that can splash or drip. Group raw poultry, raw red meat and raw seafood so they do not touch each other or other foods. Label and date, and rotate stock first-in, first-out to limit time in storage. Keep the fridge or coolroom at 5°C or colder and check it regularly. Use separate, colour-coded equipment Dedicate specific chopping boards, knives, tongs and containers to raw meat and poultry, and never use them for ready-to-eat food without a full wash and sanitise in between. Many venues use a colour-coding system, for example red for raw meat and a different colour for cooked or ready-to-eat, so staff can tell equipment apart at a glance. Colour-coding only works if everyone understands it and it is enforced. Train new staff on the scheme, display a simple chart near prep benches, and check that boards are not being swapped mid-shift when things get busy. Replace boards and utensils that are deeply scored or cracked. Grooves trap meat residue and bacteria that cleaning cannot reliably remove. Wash hands and manage personal hygiene Hands are the most common vehicle for cross-contamination. Wash them thoroughly with soap and warm running water, then dry with single-use towel, immediately after handling raw meat or poultry and before touching anything else, especially ready-to-eat food. Do not rely on gloves as a substitute for handwashing. Gloves become contaminated exactly like bare hands, so change them and wash underneath whenever you switch from raw meat to another task. Cover any cuts with a brightly coloured waterproof dressing. Avoid touching your face, phone or hair while working, and never wipe hands on your apron or a general cloth after handling raw meat, as this simply spreads bacteria to the next surface you touch. Clean, then sanitise, every contaminated surface Cleaning and sanitising are two separate steps. Cleaning with detergent and water removes visible grease, food and grime. Sanitising then reduces the remaining bacteria to a safe level. Sanitising a dirty surface does not work, so you must always clean first. After any contact with raw meat or poultry, clean and sanitise the board, bench, knives, sink and taps you used. Follow the sanitiser manufacturer's instructions for dilution and contact time, and allow surfaces to air dry where possible. Scrape and pre-clean to remove visible residue and juices. Wash with hot water and detergent. Rinse if the product requires it. Apply sanitiser at the correct dilution and leave it for the stated contact time. Air dry rather than wiping with a potentially dirty cloth. Launder or replace cleaning cloths frequently, and keep separate cloths for raw-meat areas. Separate raw and ready-to-eat in space and time Where you can, prepare raw meat and ready-to-eat food in different areas of the kitchen, or at least on different benches. If you only have one bench, separate the tasks by time: prepare all your ready-to-eat food first, then clean and sanitise thoroughly, and only then start on raw meat. Keep raw-meat prep tools, containers and waste well clear of plated food and service areas. Watch for splashes when trimming, rinsing or portioning, as fine droplets of raw juice can travel further than staff expect. Handle deliveries carefully too. Open outer packaging away from open food, and discard soiled packaging straight into the bin so it cannot contaminate benches or hands. Cooking is the final control, not a fix for contamination Thorough cooking is your last line of defence. Cook poultry and reheated meat dishes to 75°C in the thickest part, measured with a clean, sanitised probe thermometer, to destroy the bacteria raw meat carries. Hold hot food at 60°C or above and cold food at 5°C or below. However, cooking only protects the food that actually gets cooked. If raw juices have already reached a salad, a bread roll or a cooked chicken waiting to be sliced, no later cooking step will make that food safe. That is why prevention at the handling and storage stage matters so much. Apply the 2-hour/4-hour rule to any potentially hazardous food left in the danger zone, and cool cooked meats using two-stage cooling: from 60°C to 21°C within two hours, then 21°C to 5°C within a further four hours. Common myths and mistakes to avoid One of the most persistent mistakes is washing raw chicken or meat under the tap before cooking. This does not remove bacteria; instead, splashing water spreads contamination across the sink, taps and nearby surfaces. Cooking to 75°C is what makes meat safe, not rinsing. Another common error is reusing a plate or board that held raw meat for the cooked product, for example carrying raw sausages to the grill and returning cooked ones on the same plate. Always use a clean plate for cooked food. Marinades that have touched raw meat are also contaminated. Never reuse raw marinade as a sauce or basting liquid unless it is boiled first, and keep marinating meat covered in the fridge, not on the bench. Checklist: Raw meat and poultry stored sealed, on the bottom shelf, below ready-to-eat food at 5°C or colder. Separate, colour-coded boards, knives and utensils in use for raw meat. Hands washed and dried after every contact with raw meat. Surfaces, boards and tools cleaned then sanitised after raw-meat contact. Cooked food placed only on clean plates, never ones that held raw meat. Poultry and meat cooked to 75°C core, checked with a sanitised probe. Marinades that touched raw meat discarded or boiled before reuse. Raw and ready-to-eat prep separated by area or by time and cleaning. Common mistakes: Washing raw chicken or meat under the tap, which splashes bacteria around the sink and benches. Returning cooked meat to the same plate or board that held it raw. Storing raw meat above or beside ready-to-eat food where juices can drip. Relying on gloves without changing them or washing hands between tasks. Sanitising a surface that is still visibly dirty instead of cleaning it first. Reusing raw marinade as a sauce without boiling it. Using scored or cracked boards that trap raw-meat residue.
