In addition to his personal achievement, Theno’s efforts in creating one of the foodservice industry’s most comprehensive food-quality and safety programs has led to numerous awards and distinctions for the company. In 2004, The International Association for Food Protection presented Jack in the Box Inc. the prestigious Black Pearl Award, given annually to one company that advances food safety and quality through consumer programs, employee relations, educational activities, adherence to standards, and support of IAFP’s goals. Also that year, NSF International (formerly the National Sanitation Foundation) named Jack in the Box Inc. one of four winners of its first Food Safety Leadership Awards, recognizing groundbreaking achievements that help protect the public from foodborne illness.

“Dave will leave behind a legacy that will persevere for years to come,” said Linda Lang, chairman and chief executive officer for Jack in the Box Inc. “His passion for ensuring food safety and unwavering commitment to quality assurance not only established Jack in the Box as a leader in these areas, but raised the bar on industry standards and helped create a much safer food supply chain for others in the industry as well as consumers.

“We’re fortunate to have in Ann Marie McNamara and Derek Walker such seasoned experts in their respective fields to maintain the integrity of our food-safety and R&D programs.  They have big shoes to fill, but we’re looking forward to the tremendous contributions that they’ll be making to the organization.”

McNamara was previously Vice President of Food Safety and Scientific Affairs at Silliker, Inc., the world’s largest food-testing company and a leader in food-safety consulting and auditing services dedicated to helping companies find practical solutions to food safety and quality challenges throughout the supply chain. A renowned scientist with nearly two decades of industry and regulatory experience, McNamara joined Silliker in 2003 after serving as Corporate Vice President of Food Safety and Technology for Sara Lee Corp., where she developed their first corporate food-safety division. From 1992 to 1999 she served as Director of Microbiology for the Food Safety and Inspection Service of USDA. She is a co-author of several major U.S. food-safety initiatives including the USDA’s “Pathogen Reduction/HACCP Rule,” President Clinton’s Food Safety Initiative, and FDA’s “Healthy People 2010.” She received the Secretary of Agriculture’s Superior Service Award five times in her seven-year career at USDA. She was appointed by three Secretaries of Agriculture to serve nine years on the National Advisory Committee on Microbiological Criteria for Foods, which provides impartial, scientific advice to federal food-safety agencies for use in the development of an integrated national systems approach from farm to consumption to assure the safety of domestic, imported, and exported foods.
