The chemical and nutritional properties of microalgae are well known, which has led to an ever expanding industry for foods and dietary supplements both in terms of quantity and products. Little has been done to regulate or control quality and assurance in the applied phycology industry and it is known that it varies considerably. Nutritional aspects of produced biomass and consumption as dietary supplements have become issues of concern, especially since the industry is lucrative and fast growing. Various claims are made regarding dietary and food supplements that include health, nutrition, structure and functioning, many often unsubstantiated. Although quality is a subjective term many organisations are involved in testing, controlling and determining criteria. Today quality is more than just standards where it is an integrated quality management approach involving amongst others hazard analyses and critical control points (HACCP) practices. Microalgae are not recognised as a food or food supplement and they are also not categorised under herbals or botanicals, but as other supplements. Produced microalgal biomass is subject to contamination from the entire range of contaminants and pathogens. Contamination of products by algal toxins in mixed culture populations also occurs. The industry has largely regulated itself, but there is considerable scope for improvement. There is a need for support and dissemination of information in the industry.
