　　Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of guanidinoacetic acid (GAA) when used as nutritional additive in feed and water for drinking for all animal species. The FEEDAP Panel concludes that GAA at 1,200 mg/kg complete feed is safe for chickens for fattening, piglets and pigs for fattening. This concentration in complete feed would correspond to maximum concentrations in water of 600 mg GAA/L for chickens for fattening, piglets and pigs for fattening. The Panel is not in a position to conclude on a safe level of GAA in laying/reproductive birds. In the absence of data on ruminants and salmonids, the FEEDAP Panel cannot conclude on the safety of GAA for all animal species. There is no concern on consumer safety resulting from the use of GAA in feed for poultry and pigs at the proposed conditions of use. The limited data do not allow to conclude on the safety for the consumer when the additive is used in feed for ruminants or fish. GAA is not toxic by inhalation, it is not an irritant to skin and eyes, and it is not a dermal sensitiser. The FEEDAP Panel concludes that the use of GAA as feed additive is not expected to pose a risk to the environment. The use of the additive under assessment in animal nutrition at the proposed conditions of use has the potential to be efficacious in all growing avian, Suidae and ruminant (except for preruminants) species; in growing fin fish other than salmonids and in frog. It is not possible to conclude on the efficacy of the additive in other species, and in reproductive animals.
