The plasticizer Bisphenol A (BPA) is banned in baby bottles in many industrialized countries due to safety concerns. We provide a pilot view on the potential BPA exposure of bottle-fed children in sub-Saharan Africa through an enquiry on availability, accessibility and affordability of plastic baby bottles, usage pattern, and risk perception. An observational survey was conducted in a randomized group of vending sites (34 pharmacies; 87 shops and markets), in three cities (Yaoundé, Foumbot, Bafoussam) in Cameroon (two regions), and in two cities (Lagos, Port Harcourt) in Nigeria (two states). Interviews in vending sites and group discussions were conducted with 248 mothers. Cameroon and Nigeria showed a largely comparable situation. Plastic baby bottles are largely imported from industrialized countries, where a label indicates the presence/absence of BPA. In pharmacies most plastic baby bottles are labeled as BPA-free, whereas most bottles sold in shops are not BPA-free. BPA-containing bottles are more accessible and affordable, due to sale in common shops and lower costs. The meaning of the label BPA-free is unknown to both vendors and customers: the BPA issue is also largely unknown to policy makers and media and no regulation exists on food contact materials. The wide availability of BPA-containing baby bottles, lack of information and usage patterns (e.g. temperature and duration of heating) suggest a likely widespread exposure of African infants. Possible usage recommendations to mitigate exposure are indicated. Risk communication to policy makers, sellers and citizens is paramount to raise awareness and to oppose possible dumping from countries where BPA-containing materials are banned. Our pilot study points out relevant global health issues such as the capacity building of African communities on informed choices and usage of baby products, and the exploitation of international knowledge by African scientists and risk managers.
由于安全方面的担忧,许多工业化国家已经禁止在婴儿奶瓶中使用增塑剂双酚 A(BPA)。我们通过调查婴儿奶瓶在撒哈拉以南非洲地区的供应情况、可及性和可负担性、使用模式以及风险认知,初步了解了该地区婴儿通过奶瓶摄入 BPA 的潜在情况。我们在喀麦隆(两个地区)的雅温得、丰博和巴富萨姆三个城市以及尼日利亚(两个州)的拉各斯和哈科特港两个城市的随机销售点(34 家药店、87 家商店和市场)进行了观察性调查。在销售点进行了访谈,并与 248 位母亲进行了小组讨论。喀麦隆和尼日利亚的情况基本相似。塑料婴儿奶瓶主要从工业化国家进口,这些国家的标签会注明是否含有 BPA。在药店,大多数塑料婴儿奶瓶都标注为不含 BPA,而在商店出售的大多数奶瓶则不含 BPA。由于在普通商店销售且成本较低,含有 BPA 的奶瓶更易获得且价格更实惠。供应商和消费者都不知道“不含 BPA”标签的含义:政策制定者、媒体对 BPA 问题也知之甚少,并且没有关于食品接触材料的规定。含有 BPA 的婴儿奶瓶广泛供应,信息缺乏以及使用模式(例如加热温度和持续时间)表明非洲婴儿可能广泛接触 BPA。为降低接触风险,我们提出了一些使用建议。向政策制定者、销售者和民众进行风险沟通至关重要,以提高他们的认识,防止已禁止使用含 BPA 材料的国家向非洲倾销此类产品。我们的初步研究指出了一些相关的全球卫生问题,例如提高非洲社区在婴儿产品使用方面的知情选择和使用能力,以及非洲科学家和风险管理人员利用国际知识的问题。
