Dr. William Sperber is a renowned food microbiologist who has been appointed five times by the U.S. Secretary of Agriculture to the National Advisory Committee on Microbiological Criteria for Foods and has been recognized for his pioneering work at the Pillsbury Co. in the development of the Hazard Analysis and Critical Control Points (HACCP) food safety program model. 
 
During his career, Dr. Sperber worked for three major food companies—Best Foods, Pillsbury and Cargill—and has become one of the world’s experts in controlling the microbiological safety and quality of foods. 
 
A former chair of the IFT Division of Food Microbiology and the Food Microbiology Research Conference, Dr. Sperber was appointed in 2000 to the FAO/WHO roster of experts for microbiological risk assessments. 
 
In 2001, the International Association for Food Protection presented Dr. Sperber with the Harold Barnum Industry Award, and in 2002, the American Meat Institute Foundation presented him with its inaugural Scientific Achievement Award. In 2004 he received our Food Safety Magazine Distinguished Service Award
 
Now retired, Dr. Sperber is a strategic advisor to Cargill’s food safety program and remains actively involved in professional activities on a personal level, including the development of a textbook on food safety and HACCP.
