The use of probiotics and safety concerns: A review

Abstract

Probiotics are defined as "live microorganisms which when administered in adequate amounts confer a health benefit on the host''. Most probiotics fall into the group of organisms' known as lactic acidproducing bacteria and are normally consumed in the form of yogurt, fermented milks, cereal or other fermented foods. Many of the products currently available in the market are not clearly tied to research documenting beneficial effects. Probiotics are regulated by FDA and several reports are available now for mislabeling the product claiming health benefits. As live microbial products, probiotics are potential sources of risk and there exists skeptical attitude among medical professionals and consumers who have less than optimal experiences with probiotics. This review outlines information regarding probiotics, overview of proposed regulatory guidelines and commercial probiotic products available in the market considered as safe for humans.
