This method covers procedures for the visual examination of bakery products, ready-to-eat cooked breakfast cereals, and alimentary pastes. The procedures are intended to detect and estimate post-processing surface or external contamination resulting from exposure of the processed product to contamination from rodents, birds, insects, molds and other sources of filth and decomposition.
It is not designed to detect microscopic, internal particulate filth or decomposition contributed by unfit ingredients that are agglomerated in the product. AOAC digestion methods are designed for determination of the latter. See Section 2.B. for uncooked cereal products.
