Abstract

Salmonella is the most common zoonotic pathogen around the world, there is an inadequate capacity of tests to detect this pathogenic bacterium in Libya. Therefore, this study was conducted to investigate the presence Salmonella spp in various foods from different food establishments in Tripoli, Libya. A total number of 370 samples were taken from 35 confectionery premises (170 samples of cakes, 25 of tarts), 11 poultry butcheries (55 samples of chicken meat), and 2 cattle butcheries (120 samples of camel meat). The isolates of Salmonella bacteria were investigated and identified by conventional cultures and biochemical methods such as (API20E). The typical Salmonella identified isolates were subjected to the PCR to detect invA gene. The results showed that 30/370 (8.11%) Salmonella spp were identified and distributed in 10 cake samples (5.9%), 2 tart samples (8%), 16 chicken meat samples (29.1%) and 2 camel meat samples (1.7%). The invA gene was detected in 22 isolates (73.33%), all Salmonella spp isolated from cakes and cattle meat samples are invasive strains. Overall, Salmonella spp is more abundant in poultry butchers than other food establishments in Tripoli, Libya, inclusion of PCR methods to detect Salmonella spp is highly recommended.
