The food processing industry must abide by laws and regulations, just like many other industrial entities. The responsibility for ensuring adherence with governmental health regulations falls to maintenance supervisors in the food processing industry. If certain foods are not treated properly, they can contain dangerous substances. So, this can have a number of bad effects. One of the reasons fast-food establishments and restaurants place such a high priority on sanitation procedures is that they see safety precautions as an essential component of their business.
