Cleanroom facilities for micro-electronics, pharma-biotech, medical devices and healthcare do differ significantly from high-care / high-risk food processing facilities. Still, food processing is an interesting area for professionals with a contamination background and vice versa. In a world full of classifications and requirements (ISO-14644-1, EU-GMP, FDA, e.g.) the lack of distinct cleanliness requirements for the food industry is noticeable. This is obviously because there are many different types and formats of food products. As hygiene in food processing includes contamination control, the vast variety in substances, processes, and huge volumes make the food processing world take a different approach. The main differences will be addressed, the challenges discussed, and a follow-up case study article will illustrate the results.
