we have two different production departments (confectionery and nut roasting) that have different allergens. We use cleaning utensils of different colours for each department to manage allergens. Previous quality manager has taken an extra step and separated the utensils by more colours for each process (before thermal process and after thermal process for each department, but the processes are not sepparated by walls in each department). Because our products are low risk I would like to use only one colour for each department (green for whole nut roasting and yellow for whole of confectionery). Would this pose a risk for products? The employees mix the cleaning utensils at the moment and I want to make the cleaning process easier.
