Temperature control generally is a key part of food production as it protects against microbial hazards and often maintains quality too. For example, my factory makes meat products and we control both the environmental temperatures to keep the production rooms, storage chillers and freezers to suitable temperatures, and we keep records of temperatures in all areas using an electronic probe system that is linked around the factory and monitors and alerts if there is an issue. You could use manual probes or data loggers if suitable to your operation.
The product temperature is controlled throughout the process. So the operatives handing the raw meat will take the temperature using a probe every 30 minutes and record it on a product control sheet. The cooking temperature in the oven is recorded on the cooking record sheet. The temperature post-cook when being handled and pouched is also recorded every 30 minutes. Temperatures are also periodically checked by QAs. Temperature is also taken when we take the finished packed product from the storage freezer and load onto vehicles to take to the customer, and this is recorded by a QA on their dispatch sheet.
So you can see temperatures are controlled and recorded throughout the process. I imagine temperature is part of your
HACCP plan and
CCP if cooking (unless haggis apparently).
What do you produce? What do you do currently for temperature control and records?
