A retrospective study of laboratory data analysis on Salmonella serotypes was conducted in four states across the northern region of Malaysia including Perlis, Kedah, Penang and northern Perak. The increasing cases of antimicrobial resistant due to Salmonella spp. And various Salmonella serotypes being isolated from meat samples are alarming and this increases the chance of foodborne outbreak. Therefore, the aim of this study was to determine presence of various different Salmonella serotypes in meat samples received from year 2013 until 2017 by the Veterinary Public Health Section, Regional of Veterinary Laboratory Bukit Tengah, Penang. A total of 821 meat samples were sent for Salmonella isolations and serotyping and 117 different Salmonella serotypes were identified from poultry, buffalo, beef and pork meat. The most prominent serotypes were Salmonella ser. Enteritidis (10.23%), Salmonella ser. Typhimurium (8.89%), Salmonella ser. Senftenberg (7.43%) and followed by Salmonella ser. Brancaster (5.35%) and Salmonella ser. Albany (5.23%). Different patterns of predominance of the serotypes were shown for all the meat samples. For example, in poultry meat, the dominant serotype was S. Enteritidis (24.36%). Other serotypes such as Salmonella ser. Stanley (22.22%) and Salmonella ser. Jamaica (22.22%) were the most common serotypes identified in beef meat. In buffalo and pork meat samples, the predominat serotypes were S. Senftenberg (12.62%) and Salmonella ser. Rissen (30.77%) respectively. In conclusion, the identification of Salmonella serotypes will increase the effectiveness of control and prevention of an outbreak of salmonellosis.
