Host: What is cross contact?
Bob Gravani: Well cross contact is a situation where a food processing plant might be involved in making a product that contains an allergen and one that does not and they have to be scrupulously aware of keeping those products separate. Let me give you a couple of examples, if a company makes an egg pasta versus a non-egg pasta, they have got to prevent cross contact from the food allergen to the non food allergen containing product. So they are going to scrupulously clean equipment and make sure that the allergens are kept segregated in their warehouse during the process and make these products at two separate times after extensive clean up of the equipment, etcetera. Other examples might be nuts in chocolate products or certainly nuts in baked goods. Often times we see issues related to undeclared allergens present in some products because of errors in manufacturing.
