Condições de armazenamento de produtos lácteos em supermercados de Teresina, Piauí

Abstract

Proper control of storage temperature is essential to ensure food quality and safety, especially in conditions of prolonged exposure. Thus, the study aimed to evaluate the storage conditions of dairy products in supermarkets in Teresina, Piauí. The exploratory descriptive research with a quantitative approach analyzed the temperatures of refrigerated display cases in 24 supermarkets located in five geographical areas (Center, East, North, Southeast, and South), their physical and hygienic conditions, and the storage temperature of dairy products (yogurt, milk drinks, cheese, and butter) contained in these display cases. The measurements were taken in two periods (morning and afternoon) using a properly calibrated Lasergrip® infrared thermometer. The results indicated statistically significant differences betweengeographic areas, between product types and measurement periods, as well as non-compliance between the temperature indicated on the thermostat and that measured by the thermometer used in the study. In several establishments analyzed, the temperatures of the display cases and the food itself were above the limits established by current legislation, revealing inadequacies in thermal control and potential risks to consumer quality and safety. It was concluded that the study identified inadequacies in the thermal control of the analyzed dairy products, with temperatures above the allowed limits. This highlights the need for continuous monitoring, preventive maintenance of equipment, and staff training, aiming to ensure the health of consumers and the safety of the food.
