Over the past year FDA scientists have been working on developing, validating and propagating to cooperating laboratories a method for speciation of arsenic in rice-based food products. Rice and rice-derivatives are ingredients in a wide variety of products such as rice cakes, cereals, granola/snack bars, chips, noodles, pudding, and infant formula. Each product represents a novel matrix which may or may not be compatible with the method as written. This talk will address the process of extending the scope of a method developed for rice to include other rice-based products. The difficulties of bringing new laboratories up to speed on a new method and, in some cases, new analytical techniques, will also be discussed.
