| Sumario: | Introduction: The 15th Engineering and Mechanized Combat Company of the Brazilian Army received from the Federal Revenue Service a batch of shrimp of the species Farfantepenaeus subtilis, seized due to smuggling near the border with Argentina. In cases like this, there is the possibility of allocating food items to food and nutritional security programs. However, it is crucial that they meet the microbiological requirements stipulated by current legislation. Furthermore, it is important to mention that sulfites are frequently used as a preservative agent for shrimp. However, excessive consumption of it can result in health problems. Objective: To analyze the microbiological quality and the use of sulfites as a preservative in pink shrimp (Farfantepenaeus subtilis), seized by the Federal Revenue for embezzlement, close to the border between Brazil and Argentina, in 2022. Methodology: The technique was used NMP for counting total and thermotolerant coliforms and subsequent confirmation of Escherichia coli. Staphylococcus aureus count performed on Baird-Parker agar and confirmation by coagulase. For Salmonella spp. plating was performed on selective media and confirmation in medium Rugai with Lysine®. Sulfites were quantified using the Merck® sulphite kit. Results and discussion: The value found for total coliforms was 1.5,101 MPN/g and for thermotolerants <3.0 MPN/g. The count of Escherichia coli, Staphylococcus aureus and Salmonella spp. was adequate, however, the amount of sulphite-type preservatives was 123 mg/kg, that is, above that recommended by Brazilian and Argentine legislation, which may be associated with low microbiological counts, as they act against such microorganisms. |
