The occurrence of Salmonellae in bean sprouts in Thailand.
Detection of Salmonella spp. in 344 samples of bean sprouts was attempted by pre-enriched in buffered peptone water (BPW) or lactose broth (LB) at 37°C, followed by selective enrichments, selenite cystein broth (SCB) and Rappaport medium (RV) at 43°C. Four selective media, bismuth sulphite agar (BSA), brilliant green agar (BGA), Salmanella-Shigella agar (SSA) and MacConkey agar (MA) were used for isolation.
Salmonellae were isolated from 30 (8.7%) samples.
They were serotypes lexington (56.7%), orion (16.7%), senftenberg (16.7%), tennessee (3.3%), poona (3.3%) and weltevreden (3.3%). Pre-enrichment in LB, followed by enrichment in SCB and streaking on to BSA gave the highest recoveries.
Fifteen of 30 strains isolated were sensitive to all 14 antibiotics tested.
