Microbiological tests with various food products confiimed the high 

 biotin coutent of liver and kidney, and its low concent rat i(!ii in meat (beef 

 and pork). On a dry weight l)asis, egg, most fresh \-egetal)les, and sen-era! 

 fruits are also good sources of l)iotin whereas wheat and corn prodticts 

 are consistently poor.-' ■' Biotin occurs in a large \ariety of .seeds. ^ Oat 

 seedlings contain somewhat larger amounts in the root and coUniptile tips 

 than in the roots. Although in gtMiei-al not a g )od source of biotin, meat 

 contains some (cow, calf, i)ork, hen, etc.) and a high pi'opoition i-emains 

 after cooking.'"
