The global market for probiotics has witnessed significant growth in recent years, driven by increased interest in their health benefits. However, amidst the substantial expansion of this industry, there are still challenges regarding their quality control, especially in the aspect of labelling accuracy, hence reliability. This study evaluated the labelling accuracy and availability of probiotic products in Ayawaso West Municipality, Accra, Ghana. Using a stratified sampling design, 120 pharmacies within the Municipality were randomly selected and assessed for availability of probiotics and labels scrutinized. Visual inspection of the product labels was carried out utilizing a probiotic product label assessment checklist developed as a guide. The checklist covered information including brand details, probiotic species/strains, cell quantity, ingredients, label claims, dosage instructions and expiration dates. The checklist was based on recommended labelling requirements by the Joint Food and Agriculture Organization of the United Nations and World Health Organization (FAO/WHO) and the Council for Responsible Nutrition (CRN) and International Probiotics Association (IPA). The findings from this study revealed 78.3% of pharmacies in the Ayawaso West Municipality offered probiotic supplements and/or probiotic foods. Disparities in recommended label requirements and the labels of probiotic products found within the Municipality was observed. Labelling issues were more prevalent in probiotic foods than supplements. Compliance for the probiotic supplements was 74% and 44% for the probiotic food. Common issues included lack of essential information like cell quantity or CFU (colony-forming-unit), lack of statement of specific probiotic strain contained in the product, lack of scientific references supporting health claims and un-existing bacteria names. The probiotic foods occasionally stated the genus, and some did not indicate species or strain contained in the product. The study sheds light on the gaps in labelling practices in the probiotic market in Ghana and advocates for greater compliance and proper regulation of probiotics.
近年来,由于人们对益生菌健康益处的兴趣增加,全球益生菌市场显著增长。然而,在该行业大幅扩张的同时,其质量控制仍存在挑战,尤其是在标签准确性方面,进而影响可靠性。本研究评估了加纳阿克拉阿亚瓦索西区益生菌产品的标签准确性和可得性。采用分层抽样设计,随机选择了该辖区内的120家药店,评估益生菌的可得性并仔细检查标签。利用制定的益生菌产品标签评估清单作为指南,对产品标签进行目视检查。该清单涵盖的信息包括品牌细节、益生菌种类/菌株、细胞数量、成分、标签声明、剂量说明和保质期。该清单基于联合国粮食及农业组织和世界卫生组织(粮农组织/世卫组织)以及责任营养理事会(CRN)和国际益生菌协会(IPA)推荐的标签要求。本研究的结果显示,阿亚瓦索西区78.3%的药店提供益生菌补充剂和/或益生菌食品。观察到辖区内推荐的标签要求与发现的益生菌产品标签之间存在差异。标签问题在益生菌食品中比在补充剂中更为普遍。益生菌补充剂的合规率为74%,益生菌食品的合规率为44%。常见问题包括缺乏细胞数量或CFU(菌落形成单位)等基本信息、产品中所含特定益生菌菌株的声明缺失、支持健康声明的科学参考文献缺乏以及不存在的细菌名称。益生菌食品偶尔会注明属名,有些则未标明产品中所含的种或菌株。该研究揭示了加纳益生菌市场标签做法中的差距,并倡导提高益生菌的合规性和适当监管。
