Abstract

Consumption of milk is linked to improved nutrient intake and reduced risk of child malnutrition in low and middle-income countries. However, these benefits are contingent on the safety and quality of the milk. Milk consumption may alleviate the widespread risk of malnutrition in rural Ethiopia, but milk-borne contaminants may also compromise child health. We aimed to: i) identify the types of dairy feeds used, their storage conditions, and potential risk of aflatoxin contamination; ii) assess stakeholders' knowledge about aflatoxin contamination along the value chain; and iii) assess parental practices on feeding milk to infants and young children. This qualitative study was conducted in the Sidama region, southern Ethiopia. In-depth interviews ( = 12) and key-informant interviews ( = 18) were conducted with actors along the dairy value chain. Focus-group discussions were conducted with farmers (9FGD/ = 129) and child caregivers (9FGD/ = 122). Study participants were selected to represent a rural-urban gradient, as well as low- and high- dairy cow holdings. We found that while animal-feed processors and their distribution agents had relatively good knowledge about aflatoxin, farmers and retailers did not. Feed storage conditions were poor. Many respondents linked moldy feeds to animal health but not to human health. Farmers' feed choice was influenced by cost, seasonality, and herd size. Small-holding farmers had limited access to commercial feed. Children's consumption of milk was limited to skim milk, as butter was extracted and sold for income. The high cost of dairy products also led some parents to dilute skim milk with water before feeding children, compromising the nutritional value and safety of the milk. Our findings underscore the need to address the gaps in aflatoxin and food safety knowledge, improve storage conditions, and ensure the availability of quality feed to increase the sector's productivity, but most importantly to protect consumers' health and well-being, especially infants and young children.

摘要

在低收入和中等收入国家,饮用牛奶与营养摄入改善及儿童营养不良风险降低有关。然而,这些益处取决于牛奶的安全性和质量。饮用牛奶可能减轻埃塞俄比亚农村地区普遍存在的营养不良风险,但牛奶携带的污染物也可能损害儿童健康。我们的目标是:i)确定所使用的乳制品饲料类型、储存条件以及黄曲霉毒素污染的潜在风险;ii)评估利益相关者对价值链中黄曲霉毒素污染的了解;iii)评估父母给婴幼儿喂牛奶的做法。这项定性研究在埃塞俄比亚南部的锡达马地区进行。对乳制品价值链上的参与者进行了深入访谈(n = 12)和关键信息提供者访谈(n = 18)。与农民(9个焦点小组讨论/ n = 129)和儿童照料者(9个焦点小组讨论/ n = 122)进行了焦点小组讨论。研究参与者的选择代表了城乡梯度以及奶牛养殖量的高低。我们发现,虽然动物饲料加工商及其经销商对黄曲霉毒素有相对较好的了解,但农民和零售商却不了解。饲料储存条件很差。许多受访者将发霉的饲料与动物健康联系起来,但没有与人类健康联系起来。农民选择饲料受成本、季节性和畜群规模的影响。小农户获得商业饲料的机会有限。儿童饮用的牛奶仅限于脱脂牛奶,因为黄油被提取出来出售以获取收入。乳制品的高成本也导致一些家长在喂孩子之前用水稀释脱脂牛奶,从而损害了牛奶的营养价值和安全性。我们的研究结果强调,需要弥补黄曲霉毒素和食品安全知识方面的差距,改善储存条件,并确保提供优质饲料以提高该部门的生产力,但最重要的是保护消费者的健康和福祉,尤其是婴幼儿的健康和福祉。
