Food Safety
HACCP = Hazard Analysis and Critical Control Point
developed by Pillsbury Company for NASA astronauts in 1960s since then, adopted by FDA, USDA, and Dept. of Commerce predicts hazards and controls them before they happen 1. Identify hazards (i.e., biological, chemical, and physical hazards) identify potentially hazardous foods assess risk (e.g., high, medium, low, negligible) 2. Identify critical control points def. = any point in an operation where the hazard can be eliminated, prevented, or minimized observe the handling of food throughout its lifetime identify: sources of contamination, and potential for microbes to survive or grow 3. Establish controls identify: control criteria (e.g., temperatures) corrective action 4. Monitor monitor the critical control points record the data 5. Establish corrective action take action when criteria are not met 6. Verify that HACCP is functioning
