TCS (Time/Temperature Control for Safety) food is a high risk food that requires specific time and temperature controls to remain safe for consumption. When cooling this type of food, the temperature must be reduced from 135°F to 41°F or lower - within 6 hours.
Food safety not only affects continued patronage and sales of a food service business, but also public safety.
Many businesses require food safety training, so being food safety trained will increase your chances of employment. Furthermore, businesses are willing to pay higher wages to those trained.
Raw chicken and poultry may contain harmful bacteria and washing it does not remove the bacteria. This bacteria can also be spread to other items and food - if proper procedures are not followed. The only way to kill bacteria on chicken is by cooking it to a safe internal temperature - as measured by a food thermometer.
