If your staff become infected due to eating food with elevated counts of pathogens, what is your sickness policy? Do you pay if someone is absent? Is there a risk someone could work if infected or be asymptomatic? Is it ethical that the person was made ill due to your lack of maintenance and monitoring of your site fridge? Is that any less of an ethical concern than making a consumer ill due to poor temperature monitoring of your despatch area?
As a food handling site, I'm sure you'd expect toilets to be cleaned and well maintained. But by the same argument being put forward here, is that not out of scope? After all your food handlers change and wash hands before handling food so what's the problem!
Ok, last point. What is this telling your staff about your management culture if their fridge doesn't matter? Why would the fridges in the plant matter to them if their fridge doesn't matter to you? If their health doesn't matter to you? What will that do to your food safety culture?
I'm going to lean into the 'Dumb American' stereotype for replying to this (all in the spirit of friendly online debate). I'm with TimG, it feels to me a cultural thing for Americans vs the UK, especially with the tone of your questions above. But let me add a couple of friendly counterpoints:
On sickness policy, why shouldn't every business that offers a refrigerator be required to monitor it to this level? Why just us in the food industry? The same hazard you list for employee illness exists in office buildings as much as it exists in a food manufacturing plant. And what about the outdoor construction workers who manage to keep lunch safe working in the summer heat? If they can bring lunch in a chilled lunchbox, then my employees can too. GFSI requiring us to have a refrigerator is, IMO, to eliminate the odds that employees decide to use the company's cold storage to keep their lunch, nothing more.
For toilets, yes they should be clean. But what level of monitoring would you say is sufficient? Should I ATP my toilet seats? I think you'd agree that's preposterous, but GFSI requirements call for clean restroom facilities and allow us to list them on a master sanitation schedule with visual inspections to comply. In comparison to refrigeration monitoring, I'd equate it to sticking my hand in there once a week and seeing if it's cold.
From a culture standpoint, it can go both ways: we implement a monitoring program, and now it's a fresh requirement for them to uphold. They screw up and forget to monitor the refrigerator in the breakroom, and now I have to issue disciplinary writeups. The poor QA tech who is already dealing with issues on the floor has yet another checklist to run, and of course that has to be reviewed and signed off by someone else.
I'll close with a time a customer auditor argued with me that we should be monitoring the actual temp of the refrigerator per SQF. He couldn't find anything wrong with our site in general and decided to harp on this for half an hour, "I just can't believe you're not, SQF says you must!" So I dove into the code and guidance I could find, and it is not expressly stated or even implied in SQF. When he wouldn't let it drop, even wrote it into his report demanding a CAPA, we replied that we disagreed, that 3 SQF auditors found no fault in that clause, and would consider their note for future improvements.
