Study proves efficiency of chicken production

 

 

Researchers from Universidade Federal Fluminense, in Rio de Janeiro, Brazil, showed that the production standards determined in the current legislation relating to the pre-cooling stage is sufficient for decontamination of coliforms in chicken carcasses. The research was published in the Ciência Rural journal, v.43, n.9, September 2013.

In order to compare the individual analysis and analysis batch, prioritized by the sampling officer ANVISA, in influence of pre-cooling of chicken carcasses, the researchers quantified fecal coliform in 240 carcasses collected in two steps: 120 samples before and 120 after pre-cooling stage.

The mean scores obtained on carcasses before and after pre-cooling were significantly different, with an average reduction of 0.99 log10 CFU g-1 of fecal coliform. These results show that the pre-cooling step is important for the decontamination of coliforms in chicken carcasses, which appears in the parameters of current national legislation.

The innovation of this research is to use the sampling plan of three classes, the same criterion determined by ANVISA for assessing the quality of batches of poultry meat. According to researcher Felipe Faccini dos Santos, previous research that used sampling plans of two classes may have overdimensioned the results, when compared with the results obtained in fiscal action in trade. 'With the sampling of three classes, the scientific information gets closer to the demands of product quality bodies for health monitoring at the time of their sale to the population," he says.
