GRADES AND STANDARDS FOR CANNED 

 lUNA AND TUNALIKE FISHES 



The immediately previous sections have detailed various tests 

 of quality of certain packs of canned tuna. These were in the nature 

 of consumer quality tests of the tend product of processing. Long 

 before the canned products of the tuna industry are used by consumers 

 there are many regulations and standards of State and Federal govern- 

 ment to which the industry must adhere. In addition the industry 

 has its own voluntary quality control methods. These regulations^ 

 standards and quality control methods are given in detail in the 

 follovdng three sub-sections. 



Regulations and Standards of State Governments 



Legal standards, grades, and other requirements for processing 

 canned tuna are set up and enforced by both State and Federal agencies. 

 In most states such requirements are very nominal or even non-existent. 

 In California, however, where most of the tuna is processed, there 

 are very extensive requirements and rigid enforcement vAiich came into 

 effect approximately thirty years ago. An authoidty was set up in the 

 California Department of Public Health to supervise operation of all 

 canneries within the State insofar as maintenance of adequate standards 

 of quality of raw material, sanitation in the plants, and proper 

 sterilization of the product is concerned. Enforcement of regulations 

 is carried out by supervisors and inspectors of the Department of Public 

 Health. The Department maintains such regulation over the entire fish 

 canning industry, as well as over the canning of fruit and vegetable 

 products. It also operates a research and testing labot°atory under the 

 general supervision of a member of Hooper Medical Foundation of the 

 University of California. 



Ccilifornda State sanitation requirements begin with the fishing 

 vessel which must obtain a sanitary certificate shewing that the vessel 

 has been cleaned in a satisfactory manner. The regulation with respect 

 to such cleaning is as follows:
