I was super fortunate that the first job I had, my manager was MEGA passionate about weight control and knew the legislation on average weight, sampling and checkweighing like the back of his hand. I actually have a copy of the packers' guide (out of print yet bizarrely still referenced in guidance) and have picked up SO many issues over the years of sites not understanding what they're doing, not knowing their process variability, not correcting for sampling error if not using a checkweigher, not conducting zone of indecision checks etc.
So how would you rate your knowledge of weight control? Is it an area of strength or weakness? What about auditors?
On the latter, I'm often the first person to raise issues on accuracy of checkweighing when a trading standards officer has been on site and approved the same practices. Even then, ask anyone in the food industry in the UK when you last saw trading standards and it will be at least 5 years. So what is the push to ensure sites are following the law?
