Abstract

The production of meat and bone meal from 8 rendering plants was examined for the presence of salmonellas.Of 164 samples of final product 114 (69.5%) were contaminated with salmonellas. Of 65 samples, collected at various points from the production line 35 (53.8%), and of 95 samples collected from the processing environment 79 (83.1%) were found to be contaminated with salmonellas. A total of 41 serotypes were found with S. havana, S. eimsbuettel, S. ohio and S. singapore being the most frequently isolated.Pre‐enrichment of 25g samples in buffered peptone water, followed by enrichment in mannitol selenite cystine broth at 42°C and Muller‐Kauffmann Tetrathionate Broth at 37°C and plating on Bismuth Sulphite Agar was found to yield 98.5% of the salmonella‐positive samples.
