Effect of gama irradiation (Co60) in the control of Enterococci spp. and Escherichia coli in chilled chicken (Gallus gallus) heart
The present study aimed to evaluate the efficiency of the irradiation process in the control of Enterococci spp. and Escherichia coli in chilled chicken heart samples acquired in an industry located in the West Zone of Rio de Janeiro, Brazil, using irradiation doses of 1.5 kGy, 3, 0 kGy and 4.5 kGy. These microorganisms are related to fecal contamination, and are indicators of the sanitary processing conditions of the foodstuffs. The bacteriological analyses were conducted applying the methodologies and standards recommended by Brazilian norms resolution no. 12 (BRASIL, 2001) and instruction no. 62 (BRASIL, 2003) Regarding Escherichia coli, no statistically significant difference among the four groups (control, 1.5 kGy, 3.0 kGy and 4.5 kGy) was observed (p> 0.05). The Most Probable Number (MPN) for Enterococci spp. was not proven in the investigated samples. Thus, the Co60 gamma irradiation process was effective in eliminating Escherichia coli, and the lowest dose, of 1.5 kGy, was enough to abolish this enteropathogen from the evaluated samples.
