"In October 2007 when we learned there may be a problem, we immediately instituted a voluntary recall. A number of people were sickened, including Ms. Smith. Our hearts go out to Ms. Smith and her family, as well as the others whose lives have been so affected by O157:H7. Cargill conducts nearly 400,000 tests for pathogens each year using a testing methodology that exceeds U. S. Department of Agriculture standards. We also require our suppliers to test using a methodology that exceeds USDA standards. A complete food safety system combines antimicrobial interventions, employee training and safe food-handling procedures with testing. The testing verifies the effectiveness of all of these procedures. Over the past 10 years, Cargill has invested $1 billion in ongoing meat science research and new food safety technologies and interventions. We are committed to continuous improvement in the area of food safety."
