Campylobacteriosis is the most common notifiable disease in New Zealand. While the risk of campylobacteriosis has been found to be strongly associated with the consumption of undercooked poultry, other risk factors include rainwater-sourced drinking water, contact with animals and consumption of raw dairy products. Despite this, there has been little investigation of raw milk as a risk factor for campylobacteriosis. Recent increases in demand for untreated or 'raw' milk have also raised concerns that this exposure may become a more important source of disease in the future. This study describes the cases of notified campylobacteriosis from a sentinel surveillance site. Previously collected data from notified cases of raw milk-associated campylobacteriosis were examined and compared with campylobacteriosis cases who did not report raw milk consumption. Raw milk campylobacteriosis cases differed from non-raw milk cases on comparison of age and occupation demographics, with raw milk cases more likely to be younger and categorised as children or students for occupation. Raw milk cases were more likely to be associated with outbreaks than non-raw milk cases. Study-suggested motivations for raw milk consumption (health reasons, natural product, produced on farm, inexpensive or to support locals) were not strongly supported by cases. More information about the raw milk consumption habits of New Zealanders would be helpful to better understand the risks of this disease, especially with respect to increased disease risk observed in younger people. Further discussion with raw milk consumers around their motivations may also be useful to find common ground between public health concerns and consumer preferences as efforts continue to manage this ongoing public health issue.
弯曲菌病是新西兰最常见的法定报告疾病。虽然弯曲菌病的风险被发现与食用未煮熟的家禽密切相关，但其他风险因素包括雨水来源的饮用水、与动物接触和食用生乳制品。尽管如此，对于生奶作为弯曲菌病的危险因素，研究仍很少。最近对未经处理或“生”奶的需求增加，也引起了人们的担忧，即这种接触将来可能成为疾病的一个更重要来源。本研究描述了一个监测点报告的弯曲菌病病例。对报告的与生奶有关的弯曲菌病病例的先前收集的数据进行了检查，并与生奶未报告消费的弯曲菌病病例进行了比较。与非生奶病例相比，生奶弯曲菌病病例在年龄和职业人口统计学方面有所不同，生奶病例更年轻，职业类别为儿童或学生。与生奶病例相比，非生奶病例更有可能与暴发有关。研究提出的生奶消费动机（健康原因、天然产品、农场生产、便宜或支持当地人）与生奶病例并没有很强的关联。更多关于新西兰人生奶消费习惯的信息将有助于更好地了解这种疾病的风险，特别是在年轻人中观察到的疾病风险增加的情况下。进一步与生奶消费者讨论他们的动机也可能有助于在继续管理这一持续存在的公共卫生问题的同时，在公共卫生关注和消费者偏好之间找到共同点。
