A note on the stability of Rappaport-Vassiliadis enrichment medium.
After pre-enrichment in buffered peptone water, 376 samples from chicken carcasses, minced meat, pork sausages, faeces of healthy pigs and sewage-polluted seawater were enriched in Rappaport--Vassiliadis medium prepared either 4 d or 6-7 months before use. It was observed that the two media were equally effective in detecting Salmonella spp., (82 positive samples with each medium) and in their ability to inhibit competing organisms.
