U A recent survey by the UniMetrocamp Wyden University Center showed that 90% of ready-to-eat, delivered and fast-food salads were contaminated. According to Flávio Theilacker, technical coordinator of Freitag Laboratories, the study reveals faulty handling and lack of hygiene in cutting tools, work surfaces such as counters, lack of adequate training in safety in most of the cases.
