There is a High-care area within the manufacturing site I work on. We have been experiencing temperature spikes in the room, and the thermometor was reading above 10°C, which is out of specification. We realised there are two air vents (they are fresh air that is filtered) and it is coming in on one side of the room. It is causing that area of the room to be a little warmer and then I realised that is where the temperature probe for that room is situated. I got data loggers and compared one side of the room to the other. One side is really cold, and maintains a temperature of under 10°C all of the time. The side that is cold is in the area where the product is prepared with cream etc. It is then blast frozen and moves over to the other side of the room (the warmer side) to be sliced and boxed. For now, at least the colder temperature is in the area in which the cream etc. is prepped but overall, the room should be more cold. I have considered moving the probe away from this hotspot as the overall average temperature of the room is under 10°C, however, I'm not sure what the best way to do this is in terms of food safety and also justifying my decisions and actions in an audit. Open to suggestions!
