■鸡是动物蛋白质的重要来源,营养,许多低收入和中等收入国家(LMICs)的收入。它们也是导致儿童疾病负担的肠病原体的主要储存库。食物系统存在将肠病原体从家禽传播给人类的风险,但是缺乏有关购买模式的人口数据,所有权,以及在LMICs中食用活鸡及其产品,以更好地表征这种风险。
■要评估鸡肉购买情况,所有权,和消费实践,我们在马普托使用结构化问卷进行了一项基于人群的调查,2021年莫桑比克。使用多阶段整群抽样来获得我们研究区域中具有代表性的家庭样本。为了最小化抽样偏差并确保代表性样本,我们使用地区级人口数据和估计的加权人口水平值应用调查加权.
■马普托570户户主完成了我们的调查。这些家庭中约有一半在调查日期的前一周购买了肉鸡肉(占家庭的加权百分比:44.8%)和鸡蛋(46.5%),而本地鸡肉不太受欢迎(1,950,1.1%)。鸡肉产品最常见的来源是街角商店(即,街道上的小型便利店),其次是湿市场。15.6%的家庭饲养活鸡,在进行家访时,大多数家庭的地板或地面都观察到了鸡粪。
■我们的研究结果表明,在这种情况下,家禽是动物蛋白质的主要来源。随着未来几十年中低收入国家家禽养殖的预期增长,确保城市地区鸡肉产品主要来源(街角商店和湿货市场)的食品安全对于减轻健康风险至关重要。
UNASSIGNED: Chickens are an important source of animal protein, nutrition, and income in many low- and middle-income countries (LMICs). They are also a major reservoir of enteropathogens that contribute to the burden of illnesses among children. Food systems present a risk for transmission of enteropathogens from poultry to humans, but there is a lack of population-level data on the pattern of purchase, ownership, and consumption of live chickens and their products in LMICs to better characterize that risk.
UNASSIGNED: To assess chicken purchase, ownership, and consumption practices, we conducted a population-based survey using a structured questionnaire in Maputo, Mozambique in 2021. Multi-stage cluster sampling was used to obtain a representative sample of households in our study area. To minimize sampling bias and ensure a representative sample, we applied survey weighting using district-level population data and estimated weighted population-level values.
UNASSIGNED: Heads of 570 households in Maputo completed our survey. Approximately half of these households purchased broiler chicken meat (weighted percentage of households: 44.8%) and eggs (46.5%) in the previous week of the survey date, while indigenous chicken meat was less popular (1,950, 1.1%). The most common source of chicken products was corner stores (i.e., small convenience shops on streets), followed by wet markets. Live chickens were raised by 15.6% of households, and chicken feces were observed on the floor or ground at the majority of these households during house visits.
UNASSIGNED: Our findings suggest that poultry provides a major source of animal protein in this setting. With the predicted growth of poultry farming in LMICs in the coming decades, ensuring food safety at the primary sources of chicken products (corner stores and wet markets) in urban areas will be critical to mitigate health risks.
