If a food bears a USDA Organic label, it means it's produced and processed according to the USDA standards. The seal is voluntary, but many organic producers use it. Products certified 95 percent or more organic may display this USDA seal.
A machinist is a person who uses machine tools to make or modify parts, primarily metal parts. This process of machining is accomplished by using machine tools to cut away excess material much as a woodcarver cuts away excess wood to produce his work.
Machinists operate precision metal-cutting equipment to produce metal parts according to mechanical blueprints. They use a range of cutting and measuring tools, such as lathes, drill presses, vices, micrometers and milling machines. A sharp eye for detail and mastery of metalwork equipment are necessary for this career.
