Assessment of Benefits and Risks of Probiotics in Processed Cerealbased Baby Foods Bifidobacterium Lactis Bb12

The Norwegian Scientific Committee for Food Safety (VKM) has appointed an ad hoc-group of experts to answer a request from the Norwegian Food Safety Authority regarding benefit and risk assessment of B. lactis Bb12 in baby foods focusing on the age groups 4-6 months, 612 months and 1-3 years. This assessment is based on the literature provided by the notifier as well as that found by a MEDLINE search. An notification for use of processed cereal-based baby foods (from now on called cereals) intended for infants and small children supplemented with the microorganism Bifidobacterium lactis (B. lactis) Bb12 in Norway initiated this work. Studies of potential hazards and positive health effects from cereals containing B. lactis Bb12 intended for infants and young children have not been reported in the available literature. However, reports on safety of and positive health effects from infant and follow on formula supplemented with B. lactis Bb12 are available and have been assessed by VKM. In most of these clinical studies B. lactis Bb12 was administered in combination with other probiotic strains. Clinical studies report no serious adverse events of infant formula supplemented with B. lactis Bb12. The effect of long term daily consumption of such supplemented formula by the actual age groups is not known. A few studies have demonstrated some effect of supplementing baby food with probiotics, including B. lactis Bb12, on diarrhoea and atopic eczema while other studies do not show such effects. Thus, the scientific evidence for a favourable effect of supplementing formula or solid food with B. lactis Bb12, is weak and in some cases lacking. There are no studies demonstrating a positive effect of cereals supplemented with B. lactis Bb12 intended for infants and small children. Several health claims related to probiotics have been assessed by EFSA, including claims on reduction of gastro-intestinal discomfort, normal functioning of the alimentary tract, building of the natural intestinal barrier, improvement of the general immunity, mental and cognitive developments of children and immune system of children during growth. In the opinions so far, EFSA has concluded that a cause and effect relationship has not been established between the consumption of the probiotic containing products and the claimed effect. None of the products assessed so far contained B. lactis Bb12 (1 November 2009). Commercially produced cereals are frequent given to infants
