6 pages, Kefirs are fermented beverages containing yeast and bacteria produced by the fermentation of water or milk with kefir grains. Because microorganism density may influence a product's health benefits, label accuracy regarding viable bacterial density and taxonomy of fermented foods is important. In this study, the microbiota of 5 commercial kefir products were measured quantitatively using standard plating techniques and characterized using high-resolution, long-read 16S rRNA gene amplicon sequencing. To enumerate viable lactic acid bacteria, 2 lots of each product were plated on de Man, Rogosa and Sharpe agar upon opening and following 14 d and incubated under anaerobic and aerobic conditions. Results revealed that 66% of products with a guaranteed count of colony-forming units per gram overstated microorganism density by at least 1 log, with only product E exceeding 1 × 109 cfu/g. Sequencing results demonstrated moderate product label accuracy in regard to taxonomy, yet several products contained bacterial species above the minimum detectable threshold (0.001% relative abundance) that were not included on the labels (e.g., Streptococcus salivarius, Lactobacillus paracasei). Our results demonstrate a moderate level of labeling accuracy for commercial kefir products intended for human consumption. Regulatory agencies and consumers must continue to scrutinize these products and demand a higher level of accuracy and quality.

6 p., The Mauritius Sugar Industry Research Instititute (MSIRI) maintains a Library and Scientific Information Service to serve the research staff. Major responsibilities are the acqusition, collection, evaluation and dissemination of information required to support the research and development program. After a brief discussion of the internal lines of communication with the Institute, this paper describes the various communication channels (e.g. talks, meetings, visits, demonstrations, field days, publications) wihich are utilized for the transfer of research results into practice. The creation of Farmers' Service Centers has allowed an improvement of the linkage between MSIRI and small planters.
