Though the meatpacking industry has fought almost every federal effort to mandate food safety, it has also invested millions of dollars in new equipment to halt the spread of dangerous pathogens. IBP, for example, has installed expensive steam pasteurization cabinets at all of its beef slaughterhouses. Sides of beef enter the new contraption, which blow-dries them, bathes them in 220-degree steam for eight seconds, and then sprays them with cold water. When used properly, steam pasteurization cabinets can kill off most of the E. coli 0157:H7 and reduce the amount of bacteria on the meat’s surface by as much as 90 percent. But an IBP internal corporate memo from 1997 suggests that the company’s large investment in such technologies has been motivated less by a genuine concern for the health and well-being of American consumers than by other considerations.
“We have been informed that carcasses in your plant are occasionally being delayed for extended periods of time on the USDA outrail for final disposition (up to 6 hours),” the IBP memo began. It was sent by the company’s vice president for quality control and food safety to the plant manager at the Lexington, Nebraska, slaughterhouse. It warned that the longer a carcass remains on the outrail, the harder it is to clean. With every passing minute, bacteria grows more firmly attached and difficult to kill. “This delayed carcass deposition,” the memo emphasized, “is of concern and is cause for extraordinary actions regarding such affected carcasses.” When carcasses sat for half an hour on the outrail, supervisors were instructed to find the cause for the delay. When carcasses sat for an hour, supervisors were told to spray the meat with a special acid wash. Carcasses that sat for longer than two hours, that were at highest risk for bacterial contamination, were not to be destroyed, or sent to rendering, or set aside for processing into precooked meats. “Such carcasses,” IBP’s top food safety executive advised, “are to be designated for outside (non-IBP) carcass sale.” The dirtiest meat was to be shipped out and sold for public consumption — but not with an IBP label on it.
Instead of focusing on the primary causes of meat contamination — the feed being given to cattle, the overcrowding at feedlots, the poor sanitation at slaughterhouses, excessive line speeds, poorly trained workers, the lack of stringent government oversight — the meatpacking industry and the USDA are now advocating an exotic technological solution to the problem of foodborne pathogens. They want to irradiate the nation’s meat. Irradiation is a form of bacterial birth control, pioneered in the 1960s by the U.S. Army and by NASA. When microorganisms are zapped with low levels of gamma rays or x-rays, they are not killed, but their DNA is disrupted, and they cannot reproduce. Irradiation has been used for years on some imported spices and domestic poultry. Most irradiating facilities have concrete walls that are six feet thick, employing cobalt 60 or cesium 137 (a waste product from nuclear weapons plants and nuclear power plants) to create highly charged, radioactive beams. A new technique, developed by the Titan Corporation, uses conventional electricity and an electronic accelerator instead of radioactive isotopes. Titan devised its SureBeam irradiation technology during the 1980s, while conducting research for the Star Wars antimissile program.
The American Medical Association and the World Health Organization have declared that irradiated foods are safe to eat. Widespread
