Abstract: Sururu (Mytella spp.) is a filter-feeding bivalve mollusk widely consumed in Maranhão, whose quality may be compromised by inadequate handling and marketing conditions. This study evaluated the physicochemical and sensory quality of sururu meat marketed in street markets and public markets in the municipality of São Luís, Maranhão, Brazil. Sensory characteristics were assessed before and after cooking using the Quality Index Method (QIM), as well as pH, the Eber test, total volatile basic nitrogen (TVB-N), moisture, protein, and ash content. Samples were purchased as a consumer, transported under refrigeration, and analyzed in laboratories at the State University of Maranhão (UEMA). The results indicated preservation of texture and structural integrity, while changes in odor and color were observed after cooking. Most samples showed pH values above the limits recommended by legislation, although the Eber test was negative for all samples. TVB-N values remained within the legal limit, except for one sample. Moisture, protein, and ash contents were consistent with values reported in the literature. It is concluded that, despite the satisfactory quality of most samples, the conditions observed at the points of sale reinforce the need for improvements in hygienic and sanitary practices to ensure consumer safety.
