Safety and efficacy of a feed additive consisting of guar gum for all animal species (A.I.P.G. Association for International Promotion of Gums)

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of guar gum as a feed additive for all animal species. Owing the absence of information, the genotoxic potential of the additive could not be fully assessed. From the results of tolerance studies, the FEEDAP Panel concluded that guar gum is safe for salmonids at a maximum concentration of 3,000 mg/kg complete feed. Guar gum is safe up to ~ 280 mg/kg complete feed for chickens for fattening, 375 mg/kg complete feed for turkeys for fattening, 400 mg/kg complete feed for rabbits, 500 and 600 mg/kg complete feed for piglets and pigs for fattening, respectively, 1,100 mg/kg complete feed for cattle for fattening and 1,150 mg/kg complete feed for veal calves. No conclusions can be reached on the safety for long living and reproductive animals, until the genotoxic potential of the additive is fully assessed in the framework of its use as a feed additive. The use of the additive in animal nutrition is considered safe for the consumer and the environment. In the absence of data, no conclusions could be drawn on the safety of the additive for the user. Guar gum is efficacious as a gelling agent, thickener, and contributes to stabilise canned pet feed. No conclusion can be drawn on the additive as an emulsifier.
