We previously had only 1 production line. We are now looking to commission a second production line (that will be housed in a separate room with separate HVAC). We also currently have a third processing line that produces peanut butter chips.
Our concern really revolves around allergen cross-contamination with employee traffic. Our maintenance techs, quality techs, and management staff will need to travel from one room to another and prevent allergen cross-contamination. We also want to clearly designate employees for each room so that if they are in the wrong area we can correct it right away (perhaps different colored uniforms?). We have been brainstorming some ideas around how to handle this, but we feel like we might be making it more complicated than it needs to be.
What has been your experience with handling different allergens being processed in different rooms and controlling allergen cross-contamination? Any insights you can provide for us would be greatly appreciated.
