We recently had our annual audit for BRC for packaging and was cited for not testing the distilled water we use in the humidifiers used on the printing presses. Has anyone ever heard of such a thing? Do I need to test the water, or do swabbing on the humidifiers?
How often would I test the water if I needed to go that route - every gallon jug?
I once told this to a carton box supplier and they were really surprised too.
