Although nowadays quality assurance standards and guidelines are widely applied in the food industry its application in food service establishments yet lacks behind. The objective of this study was to analyse the applicability of current standards and guidelines to the Food Service Establishments (FSE) sector. This paper describes the typical microbiological hazards that are commonly found at food service establishments, the contextual situation wherein the food service establishments work in comparison to the manufacturing industries, the requirements that food safety management systems (FSMS) for food service establishments must have, and some current standards/guidelines that have been tailored for the food service establishments.It was found that major pathogen microorganisms involved in foodborne outbreaks from food service establishments are Salmonella, Campylobacter, Escherichia coli, Listeria monocytogenes, Shigella, Yersinia, Bacillus cereus, Clostridium perfringens and Staphylococcus aureus; and that FSE work within a complex contextual situation that may hinder the applicability of current QA-standards. It was proposed that a guideline/standard (that will be translated into the FSMS) must be reliable to control the microbial hazards, simple to be easily applicable, and flexible to adapt to own circumstances. Some guidelines/standards, such as "Safer food, Better business", have those requirements and had good results but are not widely adopted.
