Release No. 0262.95 Tom Amontree (202) 720-4623 Jim Petterson (202) 720-4623 Jacque Knight (202) 720-9113 USDA ANNOUNCES APPROVAL OF TRIAL TESTS FOR STEAM PROCESS TO REMOVE CONTAMINATION FROM MEAT CARCASSES WASHINGTON, March 24, 1995--The U.S. Department of Agriculture's Food Safety and Inspection Service today announced approval of commercial test trials of a steam vacuum system to remove contamination from meat carcasses in slaughter plants. "This new process has the potential to improve food safety by effectively removing incidental visible contamination and producing product with reduced bacterial counts," said Michael R. Taylor, acting USDA undersecretary for Food Safety. The patented steam vacuum process involves a hot water spray in a vacuum nozzle, with steam sprayed above and below the vacuum head. Gauges monitor water temperature and vacuum pressure. The hot water must be maintained at 180 degrees F. Hot water sprayed on to a carcass kills some bacteria and loosens contamination such as ingesta or feces, which then is vacuumed off. Taylor said the Food Safety and Inspection Service has approved a set of procedures for trial use of the steam vacuum in beef slaughter plants owned by IBP Inc. of Dakota City, Neb., and is in the final stages of examining a proposal for tests in plants owned by Excel Corp. headquartered in Wichita, Kan. Monfort Inc., of Greeley, Colo., also is seeking USDA approval to test the patented process. FSIS based its initial approval of the protocol for the trial tests on data submitted by IBP and collected in tests conducted by USDA's Agricultural Research Service (ARS) Meat Animal Research Center in Clay Center, Neb. "I am proud of the work that the food safety scientists at the Meat Animal Research Center contributed in the development of this new technology," said Acting USDA Undersecretary for Research, Education and Economics Floyd Horn. "ARS looks forward to continued collaboration with FSIS and industry to develop new and better technologies to enhance food safety." "The data we have reviewed support the hypothesis that under certain conditions visible contaminants and associated bacteria can be removed at least as effectively by steam vacuuming as knife trimming. This promising new technology now needs to be tested thoroughly under actual commercial conditions," Taylor said. The steam vacuum processing must occur in the pre-evisceration phase of meat animal slaughter, and can be used only if the plant is operating under a documented quality control program designed to minimize the occurrence of contamination, according to FSIS guidelines for the test trials. Taylor noted that the steam vacuuming must be followed up with knife trimming if visible contamination were to remain following the procedure. Under the USDA-approved testing procedure, bacterial samples will be collected at the sites of both vacuuming and trimming procedures to compare differences in the effectiveness of the procedures. #
