A alface (Lactuca sativa) é a hortaliça folhosa mais comercializada no Brasil, sendo considerada uma cultura hortícola de grande consumo. Devido ao seu baixo valor calórico qualifica-se para diversas dietas, o que favorece grandemente o seu consumo de uma maneira geral, constituindo-se em componente imprescindível das saladas dos brasileiros [6]. . The hydroponics lettuce samples showed the lowest total and edible part weight; they were inserted into Extra rate quality standard, according to the current legislation, whereas the organic and traditional lettuce samples were inserted into First and Second rate quality standard, respectively. The lettuce samples, independently of the growing process, showed low hygienic conditions, indicated by the presence of parasites of animal or human origin, and high concentration of fecal coliforms; the organic lettuce samples showed the highest frequencies of enteroparasities and fecal coliforms concentration, followed by the traditional and hydroponics lettuce samples. Considering the obtained results, the importance of this kind of food in the transmission of enteroparasities is stressed, as well as the need of actions which improve the sanitary conditions of these products.

Certain subgroups of have congenital or acquired virulence properties that allow them to cause a wide spectrum of disease. The aim of this study was to investigate the occurrence of diarrheagenic strains in ready-to-eat (RTE) foods produced in institutional, commercial and hotel restaurants in Salvador, Brazil. The presence of virulent isolates and antimicrobial resistance were evaluated. Four hundred forty-six samples were collected and grouped into cereals and vegetables, meat-based preparations, cooked salads, raw salads, garnishes, soups and sauces, desserts and juices. were detected using the most probable number method, the presence of virulence factors in isolates was determined by polymerase chain reaction (PCR) assays, and antibiotic resistance was analyzed using the disc diffusion method. In total, 15 isolates (3.1%) of were recovered; raw salads had the highest detection rate, 1.4%, followed by cooked salads, 0.8%; meat-based preparations, 0.4%; and cereals and vegetables, 0.4%. PCR assays showed that none of the isolates had the virulence genes , or . The isolates showed resistance to nine antibiotics of the 15 tested, and the highest levels of resistance were found for sulfamethoxazole/trimethoprim, tetracycline, ampicillin, and chloramphenicol (13.3% of isolates for each antibiotic). One isolate from cooked salad had plasmid-mediated multidrug resistance to tetracycline, trimethoprim/sulfamethoxazole, ampicillin and chloramphenicol. These results suggest that RTE foods, especially raw salads, can be reservoirs of and facilitate the spread of antibiotic resistance genes to the gastrointestinal microbiota of humans.

PROCESSING, STABILITY AND ACCEPTABILITY OF MARINADE OF VONGOLE (Anomalocardia brasiliana). The vongole has economicsocial importance to the most of people in the "Todos os Santos" Bay, located in Bahia coast, Brazil; it is a product of the familiar diet and it is one of the principal rental source of this local people. In purpose to increase the mollusc sale was developed studies on the marinating of vongole, through acidification of the product with vinegar at a pH[4,5 and a boiling water treatment during 30 min.The product was stored at room temperature for 240 days and the shelf life study included microbiological, physico-chemical, chemical and sensory evaluation. The process was effective to stablish commercial sterility to the marinaded vongole. According to sensory analyses, the marinaded vongole reached acceptability index like 78-82% for the overall appearance, colour, odour, flavour and texture. The data showed that the marinade of vongole was stable during storage for 240 days at room temperature.

The present study sought to characterize the physicochemical, bacteriological and sensorial effects that alcoholic beverages exert on goat Coalho cheese. For that, goat Coalho cheeses were seasoned with alcoholic beverages and physicochemical and bacteriological analyses were performed on day 0, as well as sensory analysis. The potential consumers were expected to be slightly familiar with goat dairy products. Among the seasoned cheeses, goat Coalho cheese with beer had the best acceptability and purchase intention, a result that is associated with the typical consumption of such alcoholic beverage by potential consumers. Soft and white characteristics were the most emphasized by taste testers, what is in agreement with the instrumental color and texture. According to the principal component analysis (PCA), acid and alcoholic aromas and taste were the characteristics responsible for acceptability. Therefore, it is concluded that goat cheese with alcoholic beverages can be elaborated and have good acceptability.
