Sushi restaurants have become quite popular in Europe, with an increase in the consumption of the sashimi speciality. Pathogenic bacteria such as Listeria monocytogenes, Staphylococcus aureus, and Bacillus cereus have been reported in this kind of food. Controlling the presence and multiplication of L. monocytogenes is a challenge for food safety management systems owing to its ubiquitous prese...

To study the gastrointestinal survival and enterotoxin production of the food-borne pathogen Bacillus cereus, an in vitro simulation experiment was developed to mimic gastrointestinal passage in 5 phases: (i) the mouth, (ii) the stomach, with gradual pH decrease and fractional emptying, (iii) the duodenum, with high concentrations of bile and digestive enzymes, (iv) dialysis to ensure bile reab...

In this study, effects of thyme/cumin essential oils (EO) and butylated hydroxyl anisole (BHA)/butylated hydroxyl toluene (BHT) on physicochemical properties and storage stability of chicken patties were compared in different storage periods (0, 3, 7, 14, 21, and 28 d). It was found that there were significant (P < 0.05) differences between physicochemical properties of patty samples treated wi...

We monitored the dynamic changes in the bacterial population in milk associated with refrigeration. Direct analyses of DNA by using temporal temperature gel electrophoresis (TTGE) and denaturing gradient gel electrophoresis (DGGE) allowed us to make accurate species assignments for bacteria with low-GC-content (low-GC%) (<55%) and medium- or high-GC% (>55%) genomes, respectively. We examined ra...

The study was aimed at investigating the microbial quality of ice cream and ice pop sold in Gaborone. From the study, a variety of microorganisms were isolated. The population of bacteria was found to increase from the open ice cream samples while the pre-packed ice cream had a lower population of bacteria. The types of microorganisms were both mesophilic and psychrotrophic. The population of m...

Abstract Microbiological safety of fish is a concern consumers, industries and regulatory agencies worldwide. Among the pathogenic microorganisms, Salmonella spp. one main agents foodborne diseases should be absent in animal products. Rapid accurate identification pathogens supply chain important for both quality assurance tracking infectious within chain. In this context, study aimed to evalua...
