Food processing workers operate machinery and perform other routine tasks involved in manufacturing and/or processing a range of food and drink products. The specific activities involved in food processing will vary depending on the product. Food may be sliced, ground, mixed, dried, cooked, baked, frozen, chilled, packaged or passed through a combination of these processes before it is ready for distribution. Food processing workers are responsible for operating the machines that carry out these processes, and monitoring the progress and quality of food products. They may also check and weigh raw materials, before adding them to the process. These workers must also ensure that a work environment is kept clean and hygienic.
