The street vended foods (SVF) are very popular in China, particularly in highly adolescents populated regions such as schools. Food quality is a critical global issue, but there are few studies describe the quality assessment of SVF. In this study, the quality of SVF around a university in Kunming was evaluated, including the microbial quality, proximate composition, oil quality, and heavy metal content. Microbial results showed that the aerobic plate count (APC) and Escherichia coli (E. coli) counts ranged from 1.94 to 7.43 log CFU/g or ml, and 0.53 to 1.48 log CFU/g or ml, respectively. A portion of fried snack samples exceed the standard limit of acid value (AV) and peroxide value (POV), and the same result was observed in carbonyl group value (CGV), thiobarbituric acid (TBA) value, viscosity, and conductivity. The proximate composition of the fried snack samples varied widely, while the fat content was generally higher. The heavy metal analysis showed most samples met the safety standards, with the content of 12–51, 1–19, 12–73, and 11–88 μg/kg for As, Hg, Cd, and Pb, respectively. In conclusion, although the overall results of this study were satisfying, more attention should be given to the quality of SVF. Consequently, there is a need for additional measures to protect consumers, particularly young adults in college, from foodborne disease. [ABSTRACT FROM AUTHOR]

The aim of this study is to develop a hygienic-sanitary profile of an institutional Food and Nutrition Unit (FNU), by assessing the use of Good Manufacturing Practices (GMPs) before and after the implementation of food Quality Management Tools. In order to accomplish that, the authors employed a checklist to conduct a descriptive research on the hygienic-sanitary conditions of the FNU, and to assert whether the GMPs are efficient or not, the authors also assess the microbiological contamination of equipment, utensils, food handlers' hands, hot meals (rice, beans and meat) and cold meals (raw lettuce, beetroot, carrot and cabbage salads) after the implantation of Quality Management tools. Before their implementation, the FNU was sorted into Group III ("Deficient" - 0 to 50% of analyzed items) in all three studied sectors; afterwards, however, it was moved into Group II (51 to 75% of analyzed items). As a result, the researchers did not detect any contamination with coagulase-positive Staphylococcus, Salmonella spp or sulfite-reducing Clostridium at the temperature of 115°F (46°C) in any of the analyzed foodstuffs. However, they did observe the presence of coliforms at 113°F (45°C) in the raw lettuce, carrot, beetroot and cabbage salads. The microbiological quality of the rice, beans and meat samples was satisfactory. Neither coliforms at 113°F (45°C) nor coagulasepositive Staphylococcus were found in equipment or utensils. The food handlers' hands were free of thermotolerant coliforms, while only two of them were contaminated with coagulasepositive Staphylococcus. The study concludes that implemmenting Quality Management Tools, particularly the GMPs, is one of the basic requirements for consumers' health in the preparation of food; nevertheless, such tools must be paired with a periodic supervision by qualified especialists.

A total of 85 food handlers participated in this study to determine the hygienic status of their hands in primary schools located in the state of Selangor (Malaysia). Overall findings revealed that the fecal contamination and personal hygiene of the food handlers were well maintained with the range of mean bacterial counts from 0.18 to 0.47 log10 Colony Forming Units/cm2 during the three intervals of hand swabbing (before, during and after) preparation of ready-to-eat foods. However, the general indication of the microbiological quality (Aerobic Plate Count) was out of the standard (range of mean bacterial counts from 1.39 to 1.56 log10 Colony Forming Units/cm2) based on previous literature. This study highlighted that the food handler's adherence to Good Manufacturing Practice and Sanitation Standard Operating Procedures was insufficient and suggested that attention should be emphasized on their practices at the intervals of school recess: before, during and after the preparation of ready-to-eat foods. In addition, there is also a need in the implementation of an effective HACCP program in Malaysia school foodservice operations. [ABSTRACT FROM AUTHOR]
