A method for use in a modern slaughterhouse operation for testing carcasses to be processed for one or more characteristics indicative of a carcass containing harmful, questionable or undesirable matter is substantially automated using unique bar code labels (25) on test tube racks (17), test tubes (16) and microplates (40) along with a computer to record and display individual test results in an organized fashion. The computer reads optical density values from a spectrophotometer and calculates test results for the samples based upon these values. Positive test results are displayed prominently indicating that the corresponding carcass may contain questionable matter. The testing is done using an immunoassay which would be effective for the detection of trichinosis in swine, or a standard ELISA test effective for detecting a level of sulfamethazine in pigs indicative of the use of antibiotics. Test results are available well before the dismemberment and processing of a carcass, such that if a positive test result is encountered the corresponding carcass may be removed from the routine processing procedure. |
