概括
这项研究确定了家禽中基线坎皮洛巴克特菌的流行率,发现通过烧伤和冷却等干预措施显著减少. 多重障碍的方法有效地降低了整个鸟类,部分和碎片产品的流行率.
科学领域:
- 食品安全 食品安全
- 微生物学 微生物学
- 风险评估 风险评估 风险评估
背景情况:
- 坎皮洛巴克菌会导致胃肠道疾病,家禽加工厂实施控制措施以减少其流行.
- 量化微生物风险评估 (QMRA) 对于评估家禽加工干预的有效性至关重要.
- 此前,主要消费形式的家禽部分和碎制品的暴露评估缺乏.
研究的目的:
- 在没有干预的情况下,在家禽加工中确定基线坎皮洛巴克特的流行率.
- 评估各种干预措施在体,部分和碎碎的家禽中对坎皮洛巴克特菌的流行率的有效性.
- 开发和验证不同类型的家禽产品的暴露模型.
主要方法:
- 进行了现有文献的系统审查和元分析 (SR-MA).
- 计算了最初的坎皮洛巴克特流行率和几率比率 (OR),以量化干预效应.
- 使用商业集成商数据开发并验证了基线模型.
主要成果:
- 最初的坎比洛巴克特菌患病率为82%. 烧焦 (OR 0.15) 和冷却 (OR 0.32) 显示显著减少 (P < 0.05).
- 基线模型预测流行率为18.4% (整个鸟类),62.5% (部分) 和25.2% (碎碎).
- 一项多重障碍干预措施将流行率降至2.14% (整个鸟类),6.5% (部分) 和2.62% (碎碎).
结论:
- 干预措施显著降低了整个家禽产品类别的Campylobacter流行率和变异性.
- 开发的模型为QMRA提供了可靠的暴露估计.
- 有效的干预策略对于减轻家禽消费中的坎皮洛巴克特风险至关重要.
