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 for the target animal(s), consumer, user and the environment and the efficacy of the product CRINA® Poultry Plus as feed additive for chickens for fattening.
CRINA® Poultry Plus (CPP) is a feed additive consisting on seven active substances: benzoic acid (83 %), thymol (1.9 %), eugenol (1 %), benzylsalicylate (0.3 %), piperine (0.1 %), isoamylsalicylate (0.1 %) and trans-anethole (0.1 %). It is intended to be used as a zootechnical additive (functional group “other zootechnical additives”) in complete feed for chickens for fattening at the dose of 300-450 mg/kg complete feed.
Given the inconsistency of the data and the suggestion of adverse effects, albeit not dose-related, the FEEDAP Panel is unable to conclude on the safety of the additive at the dose range proposed.
None of the components of CPP are genotoxic and in vitro assays made with the additive gave no indication of a genotoxic potential. No metabolism/residue data are available for eugenol and piperine in chickens for fattening. Consequently, the FEEDAP Panel cannot draw any final conclusion on the safety for the consumer of CPP used as feed additive in chickens for fattening.
The FEEDAP Panel considers that the product should be treated as irritant for the skin and eyes, as well as skin sensitiser. Given the particle size distribution and low dusting potential of CPP, no adverse effects upon inhalation are to be expected.
In the absence of data on the environmental fate of piperine, isoamylsalicylate and benzylsalicylate, or the additive itself, the safety for the environment cannot be assessed.
There is insufficient evidence that CPP at the recommended dose can improve the zootechnical performance of chickens. The sensory properties of the meat from chickens fed CPP are not affected.
