Interesting. I've felt for a while that food safety has a lot to learn from health and safety. A lot of concepts overlap and can be applied.
I remember reading about the swiss cheese effect a few years back as applied to health and safety (here's a
link to one article on it). Basically it's the idea that for a major incident to occur, lots of small errors have to coincide but any one of those small "holes" could have prevented the issue.
If you think about it, there is a lot of mileage in this for food safety incidents. How many times when something has happened has at least one of the factors occurred before? E.g. a meal in a ready meal factory is packed in the wrong sleeve, to prevent this, similar sleeves are put in geographically different places (e.g. different shelves), there is a scanning system in place, there is a start and end of run check and clear down procedure between products which the team leader signs off on.
Then you have an incident, it makes it to store and you realise the shelving had been changed, the scanning system was routinely switched off because it cost OEE, the start and end checks were done "at some time" if at all due to production pressures and lines were never properly cleared down due to pressure from the high risk department...
Just like with an accident there will be many near misses or hazards reported (or there should be) before the accident occurs, we should encourage our teams to report issues like this which could lead to food safety incidents and we
must act on them.
