Recently we've carried out 2 recalls in within a week of each other (the last gap between 2 recalls was over 6 months) due to a piece of blade and a bolt coming loose from separate veg preparation machines. Our Prep Supervisor, myself (QA + Food Safety Officer) and various other members of staff throughout the business are in favour of looking into having some form of metal detection implemented but our MD is against it due to cost. I definitely see it from his point of view as we normally only get an issue of this nature once or twice a year (on a bad year) and it would involve him shelling out for a new staff member to oversee the inspection but I just wonder if these 2 incidents are a form of wake up call that we might not be so lucky next time. The blade and bolt were found by the customer before we knew the pieces were missing. We've upped our level of machine checks but that still isn't 100% fool-proof.
It's easy to say "well it's cheap when you compare it to a lawsuit when someone swallows a bit of blade and dies" but we've tried that line already. Can anyone think of a more compelling argument or is this something where we just have to accept the decision and let what happens happen?
