After many years of running as an allergen free facility, my company has now decided to start producing a product that contains wheat gluten by way of beer. Our plan is to bring in only the amount that we need to complete a run in sealed plastic totes, but store any leftover open totes until the next run. Some people are suggesting allergen labeling and storage in a gated, locked area with spill containers for each tote. Others suggest allergen labeling and storage in a gated locked area, but just surrounding the gated area with spill blocker pigs or absorbent booms. While yet others just want to sticker the totes.
What are the rest of you doing for segregated storage of allergenic liquid product?
