Accurate allergen labeling is important in any food safety plan. Cross-contact problems can make any label ineffective. 

Make sure labels contain accurate information about ingredients that may be allergens and ensure that the right label is on the package. Your suppliers should accurately identify allergens in the products they provide, and packaging suppliers should accurately print ingredient information on the labels. 

To make sure ingredients and products all have the correct labels to track potential allergens, you might monitor continuously with a bar-code scanner. If that technology is not available to you, you might check labels periodically by visually inspecting them. 

Here is an example of an Allergen Process Preventive Controls form showing packaging controls that may have been identified on the Hazard Analysis form.

Later, you will verify that the labels are effective at preventing allergens from getting into products unintentionally.
