Good afternoon everyone!
I would appreciate your opinion.
Environment: SQF food manufacturer
Very tiny food residues (like the tip of a pen or a tiny little bit larger), mainly pieces of potatoes' skin, found during verification activities on the conveyor belts of the potato slicer, AFTER the night complete cleaning and sanitation procedures.
I would say that it might even be almost impossible to remove them all, since they might get jammed into the mesh of the conveyor.
But it's also true that we perform ATP reading every day after each cleaning.
ATP can detect at a molecular level, way smaller than anything that is visible by the naked eye.
So, if ATP is a standard, those tiny little visible pieces shouldn't be there (btw, the ATP readings are always good, around 30, so either the operator is picking clean areas or I don't know!)
What do you think?
Finally, how about thin hair-shaped residues on the blue conveyor (potatoes intake)?
The basic question is: Is this acceptable, or should we ask to the external contractor (night cleaning company) to be more thorough and get crazy to remove any possible residue?
