Abstract

The food irradiation process has been used since the early twentieth century and is technologically established as an important conservation method by eliminating or reducing pathogenic microorganisms, ensuring food quality and safety. The aim of this research was to verify the effect of a gamma irradiation process (Co60) and identify the presence of Campylobacter spp. in chilled chicken hearts, sold in an industry under sanitary inspection, located in the West Zone of Rio de Janeiro/RJ. The hearts of 50 chickens were collected randomly and separated into two groups, one contaminated (CAMPY) on purpose with the intention of observing the efficiency of the gamma irradiation (Co 60 ) process in the control of Campylobacter spp., and the other group (NC) naturally derived from the industrial plant. The two groups (contaminated and uncontaminated) were divided into four subgroups, CONTROL samples (non-irradiated), and samples submitted to 1.5 kGy, 3.0 kGy and 4.5 kGy doses, all samples were kept under refrigeration. At the end of the study, the presence of Campylobacter spp. was observed in samples derived from the industry, while the irradiation process was efficient in the control of Campylobacter spp. at 1.5 kGy, 3.0 kGy and 4.5 kGy.
试验分析:γ辐照(Co60)对控制冷鲜鸡(Gallus Gallus)心脏弯曲杆菌的影响
食品辐照工艺自20世纪初开始使用,并在技术上确立为一种重要的保存方法,通过消除或减少致病微生物,确保食品质量和安全。本研究的目的是验证伽马辐射过程(Co60)的影响,并确定在位于里约热内卢西部地区的卫生检查行业销售的冷藏鸡心中是否存在弯曲杆菌。随机收集50只鸡的心脏,分为两组,一组是故意污染的(CAMPY),目的是观察γ辐射(Co 60)过程对弯曲杆菌的控制效果,另一组(NC)是由工业工厂自然产生的。两组(污染和未污染)分为4个亚组,对照样品(未辐照)和1.5 kGy, 3.0 kGy和4.5 kGy剂量的样品,所有样品均冷藏保存。在研究结束时,在来自工业的样品中观察到弯曲杆菌的存在,而在1.5 kGy, 3.0 kGy和4.5 kGy的辐照过程中,弯曲杆菌的控制是有效的。
