Patent ID: 7776266

Claim:
A method for providing a device for testing for the presence of harmful contaminants in a food sample, comprising: forming in a substrate a vessel comprising an open top and an interior cavity in communication with the open top, wherein said interior cavity is adapted for receiving and accommodating a disposable container to hold a food sample; hingedly connecting a mechanical liquefier to the open top of said vessel, said mechanical liquefier being movable to a closed position for sealing the open top of the vessel; configuring said mechanical liquefier with a blade assembly insertable into a disposable container in said interior cavity of said vessel in the closed position for mechanically converting the food sample into a liquefied form; installing a radiation detector into said substrate proximate said vessel for indicating the presence of ionizing radiation in the food sample at amounts exceeding normal background levels to detect the presence of a radioactive agent as the harmful contaminant; and forming in said substrate a test assay supply compartment for containing at least one test assay, the test assay comprising at least one assay reagent having an affinity for at least one harmful contaminant.
