Consumer confidence in halal integrity of the unique and various food products provides Hat Yai, Thailand a great potential for a global destination of Muslim-friendly tourism. Islam prohibits the consumption of pork and its derivatives in any food products. The issue of food adulteration and contamination, particularly in the processed halal meat products with pork and its derivatives, greatly concern Muslim consumers. The aim of this study was to detect the presence of pork DNA from processed meat products collected from self-proclaimed “halal” Muslim street food stalls at Hat Yai, Thailand. Thirty-six samples of various processed meat products were randomly collected from seven Muslim street food stalls including patties, meatballs, and sausages containing processed chicken, beef, or a mixture of various meats. The detection of the presence of pork and its derivatives was performed by a conventional polymerase chain reaction (PCR) technique based on the pork-specific primers for a conserved region in the mitochondrial (mt) 12S ribosomal RNA (rRNA) gene. The results revealed that three out of the thirty-six samples (8.3%) were positively identified to contain porcine DNA by the detection of the expected single band of size 387 bp. The DNA method conveniently provides reliable results for routine food analysis for halal requirement. Overall, the study highlights the importance of halal integrity between the producers, suppliers, and street food business owners to provide halal food products particularly to Muslim consumers.

The aim of this study was to report the detection of methicillin-resistant <i>Staphylococcus aureus</i> (MRSA) strains at a veterinary university goat breeding farm and their characteristics. A total of 278 samples collected from animals, milk, environment and farm personnel between June 2006 and March 2008 were examined. The identification of <i>S. aureus</i> isolates was performed by a species specific PCR assay. All detected isolates were tested for resistance to oxacillin and other antimicrobials by phenotypic methods and for the <i>mecA</i> gene by PCR method. Eight MRSA were detected in this study. Five of them originated from goat’s milk and three were recovered from one human carrier of the farm personnel. All obtained MRSA isolates were clonally consistent and were characterized as: <i>SCCmec</i> type IV, spa type t064, seb positive and for genes encoding TSST-1, PVL and exfoliative toxins A and B negative.

Histidine Decarboxylase Activity

Enterococci were presented in all tested samples of raw cow milk (six samples) at the level 10<sup>3</sup>&ndash;10<sup>5</sup> CFU/ml, fresh cheeses (five samples) at the level 10<sup>2</sup>&ndash;10<sup>6</sup> CFU/g and semi-hard cheeses (five samples) at the level 10<sup>3</sup>&ndash;10<sup>5</sup> CFU/g. All 33 isolated Enterococcus strains were screened for decarboxylase activity by usage differential growth medium and 20 of them possessed tyrosine decarboxylase activity. A collection of eight strains with the strongest decarboxylase activity were identified by species specific PCR as E. faecium (Z3, Z4, Br4 and 6/4D strains) and E. faecalis (Ž4, 3/3C and 4/1A strains). Enterococcus spp. Z1 strain was not identified at the species level by used methods, but the genus was confirmed by PCR method. Their tyrosin decarboxylase activity was confirmed by TLC and detection of tdc gene. Z1, Z3 and Z4 strains showed also histidine decarboxylase activity on the differential growth medium with histidine, but this activity was evaluated by TLC as a false positive reaction of medium.

Pcr Techniques

A polymerase chain reaction (PCR)-based molecular method to detect Phomopsis sclerotioides in soil was developed using a species-specific primer pair. To improve sensitivity of the detection, three PCR techniques were used; namely, nested PCR using the primer pair internal transcribed spacer (ITS)1 and ITS4, time-release PCR using two different DNA polymerases (recombinant Taq and AmpliTaq Gold), and fluorescent PCR to obtain fluorescent-labeled PCR products that can be analyzed by capillary electrophoresis. The latter two techniques were combined and termed nested time-release fluorescent (NTRF)-PCR. The minimum concentration of DNA required to obtain species-specific PCR products successfully was 50 fg/μg. Using the NTRF-PCR method, the fungus could be detected in sandy soil that was artificially infested at a density of 10 CFU/g. The pathogen was detected in most soil samples collected from commercial cucumber fields in which visual disease symptoms had appeared, and even in samples collected from fields where visual disease symptoms had not appeared. To prevent the invasion and establishment of root-inhabiting pathogens such as P. sclerotioides, it is critical to detect the fungus in soil as soon as possible after its introduction into a cucumber-growing region.
