摘要

健康和安全的食品生产是国际出口加工厂的一个重要问题。通过清洁和消毒,可以在加工厂的每个阶段从各种来源污染鱼类的细菌数量保持在最低限度。在本研究中,旨在确定不同消毒剂对形成鱼类加工厂常驻菌群的菌株的有效浓度。在这项研究中,测定了4种不同消毒剂(氯、季铵化合物、戊二醛和过氧化氢)对从鱼类加工厂不同部位分离的细菌的有效性。采用定量悬浮法测定不同浓度消毒剂的抑菌效果。在我们的研究中,确定所有消毒剂对2%浓度的细菌都有效。测定氯化合物在低浓度(0.5%、1%)下对金黄色葡萄球菌和荧光假单胞菌没有杀菌活性。测定了季铵类消毒剂对所有分离株和双氧水化合物对不同浓度荧光假单胞菌的杀灭效果。

An investigation of the efficacy of different disinfectants on Staphylococcus aureus and Pseudomonas fluorescens isolated from fish processing plant
Healthy and safe food production is an important issue for processing plants that export internationally. With cleaning and disinfection, the number of bacteria that can contaminate fish by coming from various sources at every stage of the processing plant is kept to a minimum. In this study, it was aimed to determine the effective concentrations of different disinfectants on the bacterial strains forming the resident microflora of the fish processing plant. In the study, the effectiveness of 4 different disinfectants (chlorine, quaternary ammonium compounds, gluteraldehyde and hydrogen peroxide) was termined on bacteria isolated from different parts of the fish processing plant. The antimicrobial efficacy of different disinfectant concentrations was determined by the Quantitative Suspension Assay. In our study, it was determined that all disinfectants were effective on bacteria isolated at 2% concentration. It was determined that chlorine compounds did not show bactericidal activity at low concentrations (0.5%, 1%) on Staphylococcus aureus and Pseudomonas fluorescens isolates. The effectiveness of quaternary ammonium-based disinfectants on all isolates and hydrogen peroxide compounds on P. fluorescens at all concentrations was determined.
