plant and facilities must first be 

 inspected by specially qualified USDA or 

 Federal-State graders to determine com- 

 pliance. 



Quality Control Aids 



USDA has developed a number of visual 

 aids, color standards, and guides to 

 assure that the grade standards mean 

 the same thing in all parts of the country. 



Among the aids used to guide graders in 

 rating quality factors are handpainted 

 plaster models depicting shape, color, 

 and types of defects; special plastic and 

 glass color comparators; color photo- 

 graphs, sketches, and booklets and 

 charts illustrating types of defects and 

 other factors. 



Recently USDA initiated a program in 

 which some visual aid materials are 

 being made available for sale to the 

 public. You can get details on available 

 aids and the firms who manufacture 

 them from the grading office nearest you. 



Grapes are sized as part of the 

 grading process.
