The European Union evaluates the safety of Lasaloxi sodium as a feed additive for fattening and laying hens

On December 21, 2022, according to the European Union Food Safety Authority (EFSA), at the request of the European Commission, the European Union animal Feed Additives and Products (FEEDAP) research group issued A scientific opinion on the safety of lasalocid A sodium asa dietary additive for fattening chickens and laying hens.
On 21 December 2022, according to the European Union Food Safety Authority (EFSA), at the request of the European Commission, The EU Study Group on Additives and Products for Animal Feed (FEEDAP) issued A scientific opinion on the safety of lasalocid A sodium asa feed additive for fattening chickens and laying hens.
After evaluation, the Panel concluded that the additive is effective in controlling coccidiosis in fattening and laying hens when the additive content is 90 mg of lasaloxi sodium per kg of full price feed. Some of the original reports are as follows:

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the coccidiostat lasalocid A sodium (Avatec® 150G) for chickens for fattening and chickens reared for laying. Taking into account the results of all tolerance studies submitted for the re-evaluation of the additive, the FEEDAP Panel considers that lasalocid A sodium from Avatec®150G is safe at a maximum content of 90 mg/kg complete. The feedap panel considers that Lasalocid a sodium from Avatec® 150g is safe at a maximum content of 90 mg/kg complete feed for chickens for fattening. A margin of safety cannot be established. No conclusion on the safety of lasalocid for chickens reared for laying can be made. Three new floor pen studies showed efficacy of 90 mg lasalocid A sodium/kg complete feed reducing the adverse clinical consequences of an Eimeria infection in chickens for fattening. Considering also the previously reported positive floor pen study and the three positive anticoccidial sensitivity tests, the FEEDAP Panel can conclude on an efficient coccidiostatic level of 90 mg lasalocid A sodium/kg complete feed for chickens for fattening. This conclusion is extended to chickens reared for laying.
