Scientific Opinion on consumer safety of a manganese chelate of hydroxy analogue of methionine (Mintrex®Mn) as feed additive for chickens for fattening

Following a request from the European Commission, the European Food Safety Authority (EFSA) was asked to consider additional data provided by the applicant subsequent to the previous opinion from the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP). In its former opinion, the Panel could not conclude on the safety of manganese (Mn) from Mintrex®Mn for the consumer because of the lack of data on Mn deposition in edible tissues. Data on tissue deposition has now been provided for chickens for fattening. In a 35-day experiment with chickens for fatten ing the Mn retention from Mintrex®Mn was measured in liver, kidney, muscle, skin and fat in comparison to Mn sulphate and in relation to two supplementation levels (60 and 150 mg Mn/kg feed). There was no evidence for differences in Mnconcentrations in tissues of chickens for fattening fed Mn at two different supplementation levels and from the two Mn sources. The FEEDAP Panel concluded that Mintrex®Mn would not increase Mn deposition in edible tissues of chickens for fattening compared to other authorised inorganic Mn sources for which it would substitute. Consequently, the use of Mintrex®Mn as a feed additive for chickens for fattening is unlikely to present a safety concern to consumers.
