Procedures must stop products that do not contain an allergen from coming into cross-contact with it. As appropriate these include segregation by space or by time in storage, processing and packing; separate protective clothing; dedicated, identified equipment and utensils; production scheduling that reduces changeovers; restrictions on how allergenic materials are moved; handling of waste and spills; labelling of intermediate products; and control of changes to packaging and labels.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
