The quality of fish is affected by various factors such as, source species, freshness, and storage conditions. In free markets, exposure and handling of fish are intense, and often it is not known the origin and date of capture. The aim this work was study physico-chemical, microbiological and sensory parameters to determine the shelf life of Yellow Hake sold in street markets in the city of Santos-SP. Samples were acquired in street markets from different districts of the city and stored in a domestic refrigerator for 72 hours. And it was found that the Yellow Hake acquired on open street markets in the city of Santos-SP should be for immediate consumption. The changes are noticeable deterioration after 24 hours of storage. The results reinforce the importance of the implementation of quality programs in all sectors of sale to ensure food safety for consumers.

The strategy proposed to classify the food services by calculating the health risk score, which is globally used to reduce Foodborne Diseases outbreaks. Seven years after the event, this research aimed to investigate how Categorization of food services has been unfolding in the country. An electronic form was sent to all the health authorities who participated in the Categorization, belonging to the different spheres of government, with 29 open and closed questions aiming to evaluate the outcomes in the respective scope. All subjects were contacted via e-mail; after three attempts, phone contact was used. Thematic content analysis was applied to analyze the qualitative data. The need to propose a new method of health risk scoring for the Checklist arose, and three phases were used for that. In phase 1, different methods were identified and simulated; in phase 2, pre-test, two proposals of health risk score were tested to determine the “New Method”; and in phase 3, validation was performed on the basis of a secondary dataset containing 3072 evaluations conducted in food services in two inspection cycles. The risk score and the classifications generated by the “New Method'' were compared with the methodology adopted in the Pilot Project. Correlation was analyzed via the Lin test, and agreement through Kappa. Thirty health authorities (61%) responded the electronic form. They were mostly females over 51 years old, having more than 10 years of experience in the area of health surveillance; the vast majority is still working in the same field. Discontinuation of the Categorization strategy was observed. Regarding the category “Legacies and benefits of the Categorization project”, the most relevant subcategories emerging from the core meaning were "Positive impact of Categorization on the performance of health surveillance" and "Communication of health risk: benefits to consumer". Four subcategories were obtained from the category “Obstacles and difficulties of the Categorization project”: “Limitations of the health surveillance sector”, “Vulnerability in the Categorization process”, “Unfavorable context of the regulated sector” and “Discontinuation of the Categorization at the national level”. With respect to the use of the Checklist and the risk score, a few health authorities claimed to continue applying the checklist by Anvisa. Among the points that were raised, the core meaning “Lack of adequacy of score determination with the reality of the place” in the category “Obstacles and difficulties” must be highlighted. In this context, for the proposal of a new method with a risk score determination which is adaptable to the reality of the local health authorities, Kappa values of 0.756 (p
