Abstract

Campylobacteriosis is an emerging foodborne illness which is frequently linked to the consumption of inadequately prepared poultry. The purpose of this study was to assess the risk associated with thermotolerant Campylobacter spp. in chicken döner kebab and to estimate the number of campylobacteriosis cases due to its consumption in Tlemcen city (Algeria). In order to estimate the human exposure to Campylobacter from a döner kebab meal and the number of human cases associated to this exposure, a stochastic risk model was developed, covering the whole food pathway. The model details the spread and transfer of Campylobacter in döner kebab from slaughter to consumption and the relationship between ingested dose and the probability of developing campylobacteriosis. Information and data for the development of the risk model were obtained in this study and when not available they were obtained from other research. Whenever possible, the data were represented by probability distributions rather than single point estimates, as they were to be integrated in a probabilistic estimation of the risk using Monte Carlo simulation. We found that 86.2% of chicken meat samples were contaminated, 17% higher than 4.0 Log cfu/g. 37.5% of döner kebab samples were contaminated. It is estimated that 5 infections will occur for every 100 döner kebab consumptions and that one person in sixty-six can get a campylobacteriosis by eating a döner kebab meal. The QMRA approach allows for an overall scenario analysis. It was found that intervention during slaughter and at the cooking process of döner kebab is probably most efficient to reduce Campylobacter health risks. Furthermore, important data gaps could be identified.

阿尔及利亚西部地区烤串中弯曲杆菌的定量风险评估
弯曲杆菌病是一种新出现的食源性疾病,通常与食用处理不充分的家禽有关。本研究的目的是评估döner鸡肉串中耐高温弯曲杆菌的相关风险,并估计阿尔及利亚特莱姆森市因食用该串而导致的弯曲杆菌病病例数。为了估计人类从döner烤肉串中接触弯曲杆菌的数量以及与此接触相关的人类病例数,建立了一个涵盖整个食物途径的随机风险模型。该模型详细描述了döner烤肉串中弯曲杆菌从屠宰到食用的传播和转移,以及摄入剂量与发生弯曲杆菌病概率之间的关系。开发风险模型的信息和数据是在本研究中获得的,如果无法获得,则从其他研究中获得。只要有可能,数据就用概率分布而不是单点估计来表示,因为它们将使用蒙特卡罗模拟集成到风险的概率估计中。结果发现,86.2%的鸡肉样品受到污染,比4.0 Log cfu/g高出17%。37.5%的döner烤肉串样品受到污染。据估计,每100次食用döner烤肉串就会发生5次感染,每66人中就有1人因食用döner烤肉串而患上弯曲杆菌病。QMRA方法允许进行全面的场景分析。研究发现,在屠宰和döner烤肉串的烹饪过程中进行干预可能是减少弯曲杆菌健康风险的最有效方法。此外,还可以查明重要的数据差距。

期刊介绍: The journal Microbial Risk Analysis accepts articles dealing with the study of risk analysis applied to microbial hazards. Manuscripts should at least cover any of the components of risk assessment (risk characterization, exposure assessment, etc.), risk management and/or risk communication in any microbiology field (clinical, environmental, food, veterinary, etc.). This journal also accepts article dealing with predictive microbiology, quantitative microbial ecology, mathematical modeling, risk studies applied to microbial ecology, quantitative microbiology for epidemiological studies, statistical methods applied to microbiology, and laws and regulatory policies aimed at lessening the risk of microbial hazards. Work focusing on risk studies of viruses, parasites, microbial toxins, antimicrobial resistant organisms, genetically modified organisms (GMOs), and recombinant DNA products are also acceptable.
