Sniff Test

Misconception 1: The sniff test works

As foods age, bacteria start to multiply rapidly – especially in warm environments. Some of these bacteria release ‘off’ smells – gases and compounds which the human nose has evolved to associate with unsafe foods. You know that mouldy cheese that your friend loves? The one that smells like a footballer’s sock? The reason that some cheeses smell so off is that they contain high levels of these ‘off’ smelling bacteria.

However, these bacteria are often innocuous to humans (That cheese might smell like death, but it probably won’t kill you). By the same token, sometimes a product can be absolutely teeming with pathogenic nasties, and lack any distinct odour. Bacteria like Salmonella, Listeria and E. Coli don’t produce a distinctive smell – despite being highly dangerous to humans.

What does this mean for you?

The sniff test does work sometimes – if something doesn’t smell like it should, don’t risk it. Food waste is a lot cheaper than a long stay in hospital. The important thing is to follow food safety best practices: always abide by use by dates and storage limits – even if the item in question doesn’t smell too bad, it may well be a ticking time bomb in your fridge.
