As a local authority Environmental Health Officer, who inspects food businesses and awards food hygiene ratings, I have seen countless methods used to monitor fridge temperatures. Some work and some clearly don’t.
When monitoring a fridge, I’ve found that not everyone realises that the temperature on the fridge display only reflects the air temperature inside and not the products – and it’s the product temperature that needs to be monitored.
So how do you best monitor the temperature of the food inside a fridge? You could use a calibrated probe to directly take the temperature, but this would pierce packaging and reduce shelf life, while there is also a risk of contaminating the product. The resulting holes might also lead to questions from customers. To avoid these issues, some businesses will place a packet of butter or jelly in the fridge, which they can repeatedly probe. If the butter or jelly is not replaced frequently enough, it will become rancid. That is a situation that should be steered clear of, as the EHO wouldn’t be pleased……
There is also the issue of the time. When using a food probe, it has to be left in the food long enough for the correct temperature to be measured, after which you have to manually record the results. All of this adds up to time you probably don’t have during a busy service, and time you could better spend getting on with running your kitchen.
So how can food temperatures be monitored both accurately and efficiently?
The answer is a Tiaki sensor from Ambasense.
Tiaki sensors can be left inside your fridge, where they can directly monitor, record and report food temperatures without you having to ever open the fridge door. Tiaki is part of the next generation of the Internet of Things (IoT) and connects to the internet, to constantly log and record the temperatures it measures. Tiaki will also notify you, by email or SMS message, if it finds the temperature is out of the range you set. So when using Tiaki, there’s no need to remember to take temperatures or to them write down, you can just pop one in your fridge and get on with running your business.
