Bacteria are all around us, including on the food we eat. Good food hygiene involves slowing down and controlling the development of harmful microbes that may cause serious illness.
The Four Cs
There are four main points to remember, and they all begin with C: cross-contamination, cleaning, chilling and cooking. If you implement these within your catering establishment, you should be able to eliminate the more common food safety problems.
Cross-Contamination
Cross-contamination involves the movement of bacteria between different types of food or surfaces and equipment used within the kitchen. This most commonly occurs when raw food touches ready-to-eat food or surfaces it is prepared on. Points to remember include cleaning and disinfecting surfaces and hands before and after preparing food, keeping ready-to-eat food and raw food separate and educating your staff in the ways to avoid cross-contamination.
Why clean equipment matters in catering
Cleaning
If cleaning is practised effectively, it should remove bacteria from hands, surfaces and equipment. It is important to clean on a regular basis and not let spillages or other forms of food build up. The choice of effective commercial warewashers is extremely important, as the items placed in these machines have previously been in contact with both cooked and uncooked food as well as numerous people. Excellent robust machinery is available to help in this regard and is sold through reputable agents in the UK such as https://www.247cateringsupplies.co.uk/bar-supplies/commercial-warewashers.
Chilling
Bacterial growth slows down at reduced temperatures, so any foods that need to be chilled must not be left at room temperature for long; this also applies to ready-to-eat food. Food that is cooked should be cooled as quickly as possible before being placed in the fridge. Do check your fridges on a regular basis to ensure that they are cooling to the correct temperature.
Cooking food to a safe temperature
Cooking
High-temperature cooking will kill most harmful bacteria. Thorough cooking is most important for processed food where bacteria may be contained within the body of the food, such as sausages or minced products.
Where to find official guidance
Further Information
The Hazard Analysis and Critical Control Point (HACCP) principles are a series of national guidelines produced by the food industry and recognized by the Food Standards Agency. These help caterers to become aware of the way they handle food and help them to implement protocols to ensure that only food of the highest quality is produced in their establishment.
Summary
This piece explains the Food Standards Agency’s four Cs of catering hygiene: avoiding cross-contamination, thorough cleaning, proper chilling and correct cooking. It describes how bacteria spread between raw and ready-to-eat food, why regular cleaning and suitable equipment matter, how chilling slows bacterial growth, and why thorough cooking is vital for processed foods, pointing to HACCP guidelines for further detail.
