Scientific Opinion on the safety and efficacy of clinoptilolite of sedimentary origin for all animal species
The research paper presents a scientific opinion from the European Food Safety Authority (EFSA) regarding the safety and efficacy of clinoptilolite of sedimentary origin, a natural zeolite used as a technological additive in animal feed. Clinoptilolite consists of at least 80% clinoptilolite (hydrated calcium aluminosilicate) and a maximum of 20% clay minerals. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) evaluated the additive based on a limited database and concluded that a concentration of 10,000 mg clinoptilolite/kg of complete feed is safe for all animal species.
Clinoptilolite is not absorbed by the gastrointestinal tract and is excreted unchanged in feces, meaning consumers are not exposed to it through animal products. However, due to its high dusting potential, the panel recommends treating it as an irritant to skin and eyes, a dermal sensitizer, and an inhalation toxicant. The environmental impact of using clinoptilolite in animal nutrition is deemed negligible, as it does not accumulate in the environment.
The additive has demonstrated efficacy as an anticaking agent in various compound feeds, although there is insufficient data to confirm its effectiveness as a pellet binder. The panel suggests that the physical properties of clinoptilolite likely allow it to function as a pellet binder as well.
This research paper is significant in the field of animal nutrition and feed additives, as it provides a comprehensive assessment of clinoptilolite's safety and efficacy. It contributes to ongoing discussions about the use of natural additives in animal feed, particularly in light of regulatory requirements for safety assessments. The findings are beneficial for stakeholders in the animal feed industry, including manufacturers and regulatory bodies, as they provide evidence-based guidance on the use of clinoptilolite. The opinion also highlights the importance of thorough safety evaluations for feed additives to ensure consumer safety and environmental protection.
