RESUMO:

Beef is one of the most consumed foods and its quality is an important public health issue in informal markets. This study aimed to analyze the trade of fresh beef at the street market in Santo Antônio de Jesus, state of Bahia. This is an exploratory study carried out in three stages. In the first stage, using six electronic databases, a scientific literature review was carried out on the quality and safety of beef sold in the retail trade, methods used for quality evaluation and proposed interventions. In the second stage, seeking to characterize the issue of trade, food safety and quality of raw beef, a questionnaire was administered and meat samples were collected, which were submitted to a physical-chemical and microbiological evaluation, including: total coliform, Escherichia coli, and Salmonella spp counts. The third stage aimed to identify factors associated with consumer confidence. A quantitative study was conducted with consumers, using a questionnaire. Data were treated by descriptive statistics, Latent Class Analysis, regarding the outcome “trust” and/or “distrust” and application of a binary logistic regression model. Considering the first stage, thirty-three articles were included in the review. The methodological strategies used revealed inadequate conditions, neglects in several stages of processing and operations to maintain of quality. In the second stage, meat sellers were between 20 and 64 years of age, predominantly males (82.4%), with limited education and without professional training (64.7%). Medians for temperature and pH in the small butcher shops samples were 18.10°C and 5.75 respectively, and 21.80°C and 5.50, in supermarkets samples. The difference in pH was significant (p<0.05). The filtration test suggested quality changes in 17.65% of the samples. Total coliform counts medians were 4.90 and 4.78 log CFU/g, for the samples taken from butcher shops and supermarkets, respectively. E. coli was identified in approximately 40.0% of the samples, with medians for counts of 4.30 and 3.84 log CFU/g, for butcher shops and supermarkets, respectively. Salmonella spp. were confirmed in two samples. There was a significant association between inadequate storage conditions and microorganism counts (p<0.02). In the results of the third stage, meat purchase at the street market, increased by 3.25 times the chance (CI 1.05 - 10.04) of confidence in purchased meat, while not always buying at the same sales point reduced the chances of consumer confidence (OR 0.32; CI 0.14 - 0.71). In opinion questions, considering the meat to be unsafe and with unmet needs increased by 11.05 times (CI 3.45 - 35.37) the chance of dissatisfaction and mistrust, while unsafe feeling and family members’ health concerns reduced the chances (OR 0.07; CI 0.02 - 0.20). Furthermore, satisfaction and confidence chances increased 1.58 times (CI 1.01 – 2.49) among those who did not recognize the need for strategies to improve commerce. The results confirm a worrying scenario, a meat supply with preservation failures and non-compliance with hygienic requirements and the definition of a logistic model based mainly on loyalty practices and the establishment of trust in places and sales agents – a trust more likely built by cultural aspects rather than by specific product criteria.
