Livestock farming is common in low-income settings as a source of income and animal-sourced food. However, there is growing evidence of the harmful health effects of proximity of animals to infants and young children, especially through exposure to zoonotic pathogens. Poultry ownership is almost universal in rural Burkina Faso. Poultry feces are a significant risk factor for enteric diseases that are associated with child undernutrition. To investigate the extent of exposure to livestock feces among young children and caregivers, we conducted direct observations of 20 caregiver-child dyads for a total of 80 hours (4 hours per dyad) and recorded water quality, sanitation, and hygiene (WASH)-related behaviors. We also undertook in-depth interviews with these caregivers and focus group discussions with separate groups of men and women who were poultry farmers. Poultry and other livestock feces were visible in all 20 and 19 households, respectively, in both kitchen areas and in the household courtyards where children frequently sit or crawl. Direct soil ingestion by young children was observed in almost half of the households (45%). Poor handwashing practices were also common among caregivers and children. Although latrines were available in almost all households, child feces disposal practices were inadequate. This body of research suggests an urgent need to adapt conventional WASH and livestock interventions to reduce the exposure of infants and young children to livestock feces.
畜牧业在低收入环境中很常见,它是一种收入来源和动物源性食品的来源。然而,越来越多的证据表明,动物与婴儿和幼儿的近距离接触对健康有不良影响,特别是通过接触人畜共患病病原体。在布基纳法索农村,几乎家家户户都养鸡。家禽粪便对与儿童营养不良有关的肠道疾病是一个重大的风险因素。为了调查幼儿和照料者接触家畜粪便的程度,我们对 20 对照料者-儿童进行了直接观察,总共 80 小时(每对 4 小时),并记录了水质、卫生和个人卫生(WASH)相关行为。我们还对这些照料者进行了深入访谈,并与分别由家禽养殖户组成的男女焦点小组进行了讨论。在 20 户家庭和 19 户家庭中,分别在厨房区域和儿童经常坐或爬行的家庭庭院中都可以看到家禽和其他家畜的粪便。几乎一半的家庭(45%)都观察到幼儿直接吞食土壤。照料者和儿童中也普遍存在不良洗手习惯。虽然几乎所有家庭都有厕所,但儿童粪便处理方法并不完善。这项研究表明,迫切需要调整传统的 WASH 和畜牧业干预措施,以减少婴儿和幼儿接触家畜粪便的机会。
