Avaliação do microclima em indústrias de abate e processamento de carnes utilizando métodos da Resolução/ANVISA no9/2003

Abstract

Slaughterhouses control the environments internal temperature to ensure the quality of manufactured products. To meet this requirement, they create microclimates that alter the internal environment, interfering with the health, safety, comfort and well-being of occupants. There is a legal obligation to control indoor air quality within these air-conditioned locations, with Resolution-RE/ANVISA nº9/2003 being the general standard that regulates and disseminates the methodologies adopted in these monitoring actions in buildings for public and collective use. To investigate the effectiveness of monitoring the IAQ parameters used by the analytical methods described in Technical Standards 002 and 003 of RE/ANVISA nº9/2003 for artificially air-conditioned environments in meat processing industries. Between July 2022 and August 2023, the physical variables of humidity and air temperature were measured, in addition to the concentration levels of the chemical agent CO2 in eight industrial units of slaughterhouses. The data collected in the research and those extracted from the indoor air quality reports carried out by the companies were compared with the values recommended in the ANVISA resolution, with all establishments presenting results, for one or more parameters, outside the ranges defined in the standard. Data collection of this study had an expanded sampling approach in relation to the provisions of the sampling strategy of the resolution, providing more robust and reliable data than those obtained through the analytical methods in use, demonstrating the need for regulatory changes aimed at improving quality of the indoor air of meatpacking plant.
