Poultry is one of the most consumed meats worldwide and there are many different types of poultry products available on the market for consumers. Many poultry producers provide a variety of labeled meats based on rearing system such as organic, free-range and antibiotic-free. However, these labels often can be misleading by implying organic products are better in safety and quality compared to poultry products without additional labels. In this study, the microbiological profiles of commercial poultry products were characterized via a next generation sequencing. A variety of poultry products including whole carcass, leg, breast and thigh were purchased from local markets and subdivided by labels indicating organic, non-antibiotic, free range and no-label. According to the microbiome analysis based on the 16S rRNA gene, similar level of species richness were observed in comparison by labels, however, different parts and producers exhibited significant differences. Also, microbial similarities among groups were measured and most samples showed relatively close clustering based on the poultry part and the producer. The results emphasize potential contamination routes and the importance of the control strategy during the pre-harvest step of poultry products. The results also envision potential opportunities to improve current production procedure being utilized by industries.
家禽是全球消费最多的肉类之一，市场上有许多不同类型的家禽产品供消费者选择。许多家禽生产商根据饲养系统（如有机、散养和无抗生素）为消费者提供各种有标签的肉类。然而，这些标签往往会产生误导，暗示有机产品在安全性和质量方面优于没有其他标签的家禽产品。在这项研究中，通过下一代测序技术对商业家禽产品的微生物特征进行了描述。从当地市场购买了各种家禽产品，包括整只禽体、鸡腿、鸡胸和大腿，并根据标签分为有机、无抗生素、散养和无标签。根据基于 16S rRNA 基因的微生物组分析，标签之间观察到相似的物种丰富度水平，但不同部位和生产商表现出显著差异。此外，还测量了组间微生物的相似性，大多数样本根据家禽部位和生产商显示出相对接近的聚类。研究结果强调了家禽产品收获前阶段的潜在污染途径和控制策略的重要性。结果还设想了通过行业利用现有生产程序的潜在机会。
