J THE EFFICIENCY OF DRY COMPOSITING FOR DETECTING SALMONELLAE IN ANIMAL BY-PRODUCTS. 

 Harrington, R., Blackburn, B. 0. and Murphy, C. D. Proc. 76th Ann. Meeting USAHA, 1972, pp. 565-571. (Abstract 

 of Published Report) 



Comparisons were made between a standard method and three compositing methods for the isolation of 

 salmonellae from rendered animal by-products. Of the 61 lots examined, 43 were positive by standard methods, 43 

 were positive by composite method A 1: 47 were positive by composite method A 2 and 36 were positive by com- 

 posite method B. 



The results of the present study indicate that composite methods Aj and A 2 may be used to examine animal 

 by-products for Salmonellae with an accuracy equal to the standard methods employed.
