Avaliação quali-quantitativa da água de múltiplos usos em abatedouros de São Luís

Abstract

Water is a common good of extensive value to all humanity. It is important for all ecosystems and living beings and widely used in all food processing and industry, having required its potability to do so in order to avoid harm to public health, such as Foodborne Diseases (DTA's). In view of the need to use potable water in the food industries, it would not be different in slaughterhouses. Thus, in this work, we sought to evaluate the quali-quantitative pattern of water for multiple uses in slaughterhouses in the city of São Luís, in the state of Maranhão. The methodology consisted of preparing and applying a questionnaire in order to obtain information about the slaughterhouse, such as slaughtered species, slaughter volume (day/month), source of water used in the use and consumption of the slaughterhouse, realization and use of products for treatment of water and effluents, then mapping the collection points with the aid of the georeferencing tool QGis Version 3.20.0 in parallel with Google Earth Pro. After this, water samples were collected and sent to microbiological analysis (total coliforms and Escherichia coli) and physicochemical (bicarbonate alkalinity, carbonate alkalinity, hydroxyl alkalinity, total alkalinity, calcium, chlorides, free chlorine, apparent color, conductivity, total hardness, magnesium, hydrogen ionic potential - pH, total dissolved solids, temperature, turbidity) in an outsourced laboratory. Having the results in hand, they were evaluated as to whether or not they met the standards established by Consolidation Ordinances GM/MS No. 5, of September 28, 2017 and GM/MS No. 888, of May 4, 2021 (which amends the Annex XX of Consolidation Ordinance GM/MS No. 5, of September 28, 2017), both from the Ministry of Health, which legislate on the control and surveillance procedures for the quality of water for human consumption and its potability standard.
