Pete Fernholz remembers the days when his dad, who worked at a milk plant for 40 years, had to help take apart a milk processing system and clean it with tubular brushes. It was a costly and time-consuming step in the process of trying to assure sanitized milk. Nowadays, closed-loop systems use clean-in-place (CIP) technology, which allows pipes and other production components to be cleaned automatically with less human intervention, reducing cleaning time, costs, and possible contamination events.
Features: Pest Control: Past and Present
In today’s climate of heightened food safety scrutiny, it is hard to believe that not so long ago, attitudes about what constituted a hygienic processing environment were very different. This is especially true for pest management practices. Only a little more than 70 years have passed since Congress enacted the Federal Food, Drug and Cosmetic Act of 1938 (FD&C Act), and a little more than 100 years ago, Upton Sinclair’s The Jungle opened America’s eyes to what was happening in meat...

The principles can be applied in a variety of venues, from agricultural production to food service, from multinational corporations to small processors in developing countries. It is a systematic approach to building safety.
