The presence of food means the issue of food safety. So a plenary session here at the 21st International Congress of Refrigeration featured Dr. Elsa Murano, Undersecretary for Food Safety at the U.S. Department of Agriculture.
She told the international audience that the United States “has the best food processing and production in the world — but it is not perfect.”
