The effects of aeration in the first stage of poultry carcasses composting through the monitoring of physics parameters (temperature), chemicals (nutrients recycling) and microbiologic (total and fecal coliforms and Salmonella sp absence or presence) were evaluated. The composting trial was carried out in two stages, the first at composters with or without aeration and the second at the composting area. The maximum temperature attained, considering weekly average, in the first stage was 56.1 ºC and 66.2 ºC (with and without aeration) and 54.1 ºC and 61.9 ºC (with and without aeration), respectively for the first and second loading system, while in the second stage was 53.6 ºC and 64.6 ºC; 61.1 ºC and 66.3 ºC, respectively for the systems with or without aeration in the two loading. The results obtained showed that didn't have any difference of temperature between treatments at the first stage of the process to impede the development of Salmonella sp occurred in the first loading in both systems. However, the decrease of total and fecal coliforms as well as the absence of Salmonella sp at the compost samples in both system allow to infer about the necessity to realize the second stage as much to guarantee the biosecurity of the process as to obtain a compost with better agronomic characteristics.
