Raising poultry flocks in urban backyard settings is becoming increasingly popular across the United States, but carries a risk of zoonotic infection. In the United States from 1990 to 2014, 53 outbreaks of human salmonellosis linked to live poultry have been documented resulting in 2611 known illnesses, 387 known hospitalizations and five known deaths (Centers for Disease Control and Prevention 2015a, http://www.cdc.gov/healthypets/resources/dont-play-chicken-with-your-health-poster-24x36_508.pdf). A cross-sectional descriptive study was developed to better understand knowledge, attitudes and practices of urban backyard poultry owners regarding Salmonella risk and prevention. The study included a survey of bird health, animal husbandry and hygiene practices, and knowledge, attitudes and practices relating to Salmonella risk. Participants were videotaped while caring for their birds, and the recordings were transcribed using notational analysis to determine whether reported practices differed from observed practices. The results indicated that while a large proportion of participants knew that exposure to Salmonella is an inherent risk associated with raising poultry and harvesting eggs, their reported and observed practices would not consistently reduce risk of transmission of Salmonella and other zoonotic diseases. Approximately one in four participants reported performing practices that increase risk of inoculation, such as snuggling and kissing birds or eating/drinking near them. None of the participants were observed kissing their birds on video; however, snuggling (holding birds to clothes) or touching their face during routine care was observed in approximately two-thirds of the video recordings. The video data provided a unique opportunity to compare reported practices with actions recorded during site visits. While the differences were not statistically significant, findings from our study suggest that flock owners may not accurately report the frequency with which risky practices are performed during routine animal care. Education and outreach targeting backyard flock owners should aim to improve husbandry and hygiene practices and reduce risk of zoonotic diseases associated with raising poultry in the backyard setting.
在美国,在城市后院饲养家禽的现象越来越普遍,但存在人畜共患感染的风险。1990年至2014年期间,美国记录了53起与活禽相关的人类沙门氏菌病疫情,导致2611例已知疾病、387例已知住院病例和5例已知死亡病例(疾病控制与预防中心,2015a,http://www.cdc.gov/healthypets/resources/dont-play-chicken-with-your-health-poster-24x36_508.pdf)。开展了一项横断面描述性研究,以更好地了解城市后院家禽饲养者对沙门氏菌风险及预防的知识、态度和做法。该研究包括对鸟类健康、畜牧和卫生习惯,以及与沙门氏菌风险相关的知识、态度和做法的调查。参与者在照料鸟类时被录像,录像记录通过符号分析进行转录,以确定报告的做法是否与观察到的做法不同。结果表明,虽然很大一部分参与者知道接触沙门氏菌是饲养家禽和收获鸡蛋所固有的风险,但他们报告的和观察到的做法并不能始终如一地降低沙门氏菌和其他人畜共患疾病的传播风险。约四分之一的参与者报告了一些增加感染风险的行为,比如与鸟类依偎、亲吻鸟类或在它们附近饮食。录像中未观察到有参与者亲吻鸟类;然而,在约三分之二的录像记录中观察到了依偎(将鸟类贴在衣服上)或在日常照料过程中触摸脸部的行为。视频数据提供了一个独特的机会,可将报告的做法与实地考察期间记录的行为进行比较。虽然差异无统计学意义,但我们的研究结果表明,家禽饲养者可能无法准确报告日常动物照料过程中危险行为的发生频率。针对后院家禽饲养者的教育和宣传应旨在改善畜牧和卫生习惯,降低在后院饲养家禽相关的人畜共患疾病风险。
