Microbiological quality of ready-to-eat fresh vegetables and their link to food safety environment and handling practices in restaurants

Accepted, unedited manuscript- Published on-line 22-July-2016 Pending copyediting, typesetting, and reviewing of proof, and publishing in its final form.he increased consumption of ready-to-eat salads outside homes as a result of a fast paced lifestyle, awareness on their nutritional attributes and enhanced processing technology is well documented. This study aimed to determine the microbiological quality of fresh-cut salads vegetables in small and medium sized foodservice establishments (SMEs) and to identify risk factors and handling practices through observational assessment in order to investigate if an association between microbiological quality and visual assessment (inspection) scores can be established. A total of 118 samples fresh-cut vegetable salads were collected from 50 inspected locations and analysed microbiologically, in addition to 49 swabs of knives and cutting boards. There was no statistically significant correlation between visual assessment scores and bacteriological counts on vegetables or cutting boards. Nonetheless, the consistent relationship between inspection ratings on cross-contamination and cleaning components and Listeria spp. levels was statistically significant. This study demonstrated that overall visual assessment scores would not directly reflect the safety of salad vegetables and that the significance of microbiological assessment should be considered in relation to individual inspection components. It is necessary to place effective control measures on cleaning standards and risk of cross-contamination to improve the microbiological safety of fresh salad vegetables in SME

The influence of pre-wash chopping and storage conditions of parsley on the efficacy of disinfection against S. Typhimurium

Initial chopping of parsley before washing for subsequent processing into ready-to-eat foods later in the day is common in some restaurants. The aim was to evaluate the influence of pre-wash chopping on the S. Typhimurium decontamination by common washing and disinfection methods including the use of vinegar (4%, v/v, acetic acid), 0.25 g/l sodium dichloroisocyanurate (NaDCC), and water combined with manual agitation. This study demonstrated limited efficiency of applied methods and that holding pre-wash chopped leaves at 30 °C reduced the effectiveness of all washing solutions. Scanning electron microscopy (SEM) imaging indicated initiation of biofilm formation after 24 h at 5 °C with noticeable adhesion of cells to inaccessible folds of the vein on the leaf surface. NaDCC was shown to be the most effective solution achieving log reductions of 1.92–3.12 on intact parsley leaves. The latter being on those held at 5 °C for 4 h; However, its effectiveness was reduced by 0.73–0.93 and 1.19 log cfu/g on chopped leaves at 5 °C and on both intact and chopped leaves at 30 °C, respectively. In conclusion, strict temperature control and avoiding pre-wash chopping are highly recommended during handling of parsley for the optimal elimination of pathogenic microorganisms

Investigating a link of two different types of food business management to the food safety knowledge, attitudes and practices of food handlers in Beirut, Lebanon

Although Lebanon has a flourishing traditional and modern food businesses, which are typical both Middle Eastern (ME) and Mediterranean cuisines, knowledge and practice of food safety performance of the food service sector are limited in the whole ME region and lacking in Lebanon. To address this, a survey was conducted in Beirut to evaluate the knowledge, attitudes and practices related to food safety issues of food handlers (n = 80) in food service establishments (n = 50) and to assess the influence of management type on enactment of safe practices on food premises. Our data suggest that while respondents have limited knowledge of some aspects of food safety, substantial gaps in their knowledge and self-reported practices associated with critical temperature of foods and cross contamination remain, therefore posing health risks to consumer health. Food handlers in corporatemanaged food outlets showed a significantly higher awareness on food safe practices. It is concluded that the management type is an integral element of TPB (Theory of Planned Behaviour) that influence food handlers' practices and substantiate the need for more research work on safe food handling in the context of food safety culture framework in food businesses. Our data revealed the critical need for food safety education interventions and technical guidance fostered by synergistic participation of the private and public sector to support food handlers in SME's (small and medium sized enterprises)

Comparison of hygiene standards and food safety practices between sole-proprietor and corporate-managed restaurants in Lebanon

No embargo requiredPurposeThe objectives of this study were to compare the hygiene standards and food handling practices between sole-proprietor and the corporate-managed restaurants in Lebanon and to determine whether the variations between both groups are explained by and directly related to the type of management.Design/methodology/approachAn in-depth observation assessment of food safety environment and practices was conducted on a convenient sample of 50 food businesses in Beirut, which are typical of foodservice outlets in Lebanon and in many countries of the Middle East. The observation assessment checklist comprised six constructs of 2–7 components for analysis. It covered all areas including documentation and record-keeping requirements, which are crucial parts of a food safety system.FindingsThere was a significant difference in the visual assessment score between sole-proprietor (77.9 ± 18.4) and corporate group (48.5 ± 12.8). Food handlers' behavior and hygiene standards were significantly associated with the type of management. However, there were still critical gaps in the food safety performance of the corporate group suggesting other underlying factors than the type of management.Practical implicationsAdditional elements were drawn from this study for future food safety culture research. Understanding the food safety attitudes and perception of risks of the management representatives, leaders, or food business owners is vital to develop appropriate food safety interventions and foster a positive food safety culture in the foodservice industry.Originality/valueTo the authors’ knowledge, this is the first study not only in Lebanon (or MENA) but also in other regions to measure the association of management type, that is, sole-proprietor management and corporate management, with the food hygiene standards and food safety practices in the foodservice establishments. This paper presents new findings that will be of value for researchers in food safety and will complement the existing literature on food safety culture in the foodservice industry.</jats:sec

A Review on the Rising Prevalence of International Standards: Threats or Opportunities for the Agri-Food Produce Sector in Developing Countries, with a Focus on Examples from the MENA Region

Food safety standards are a necessity to protect consumers’ health in today’s growing global food trade. A number of studies have suggested safety standards can interrupt trade, bringing financial and technical burdens on small as well as large agri-food producers in developing countries. Other examples have shown that economical extension, key intermediaries, and funded initiatives have substantially enhanced the capacities of growers in some countries of the Middle East and North Africa (MENA) region to meet the food safety and quality requirements, and improve their access to international markets. These endeavors often compensate for the weak regulatory framework, but do not offer a sustainable solution. There is a big gap in the food safety level and control systems between countries in the MENA region and those in the developed nations. This certainly has implications for the safety of fresh produce and agricultural practices, which hinders any progress in their international food trade. To overcome the barriers of legal and private standards, food safety should be a national priority for sustainable agricultural development in the MENA countries. Local governments have a primary role in adopting the vision for developing and facilitating the implementation of their national Good Agricultural Practices (GAP) standards that are consistent with the international requirements and adapted to local policies and environment. Together, the public and private sector’s support are instrumental to deliver the skills and infrastructure needed for leveraging the safety and quality level of the agri-food chain
