Safety and efficacy of a feed additive consisting of an essential oil derived from Eucalyptus globulus Labill. (eucalyptus oil) for all animal species (FEFANA asbl).

Abstract: Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of an essential oil from the leaves and twigs of Eucalyptus globulus Labill. (eucalyptus oil) when used as a sensory additive in feed and water for drinking for all animal species. The FEEDAP Panel concluded that the use of eucalyptus oil is safe at the following concentrations in complete feed: 12 mg/kg for chickens for fattening, 18 mg/kg for laying hens, 16 mg/kg for turkeys for fattening, 22 mg/kg for piglets, 26 mg/kg for pigs for fattening, 32 mg/kg for sows, 55 mg/kg for veal calves (milk replacer), 48 mg/kg for cattle for fattening, sheep, goats and horses, 31 mg/kg for dairy cows, 19 mg/kg for rabbits, 55 mg/kg for salmonids, 58 mg/kg for dogs, 10 mg/kg for cats and 75 mg/kg for ornamental fish. These conclusions were extrapolated to other physiologically related species. For any other species, the additive was considered safe at 10 mg/kg complete feed. No concerns for consumers were identified following the use of eucalyptus oil up to the highest safe level in feed. The additive under assessment should be considered as irritant to skin and eyes and the respiratory tract and as a skin sensitiser. The use of eucalyptus oil at the proposed use level in feed was not expected to pose a risk for the environment. Since E. globulus and its preparations were recognised to flavour food and its function in feed would be essentially the same as that in food, no further demonstration of efficacy was considered necessary.

The European Commission sought guidance from the European Food Safety Authority (EFSA) on the suitability of eucalyptus oil, sourced from the leaves and twigs of the Eucalyptus globulus plant, as an additive in horse feed and products.

Key Findings for Horses:

  1. Safety Levels in Horse Feed: The EFSA’s FEEDAP Panel determined that the safe concentration of eucalyptus oil in complete feed for horses is 48 mg/kg.
  2. Consumer Safety: There’s no risk for humans consuming products from horses that were fed eucalyptus oil up to the stated safe levels.
  3. Health Considerations: The eucalyptus oil under review can irritate the skin, eyes, and respiratory tract. Additionally, it might cause allergic reactions on the skin.
  4. Environmental Impact: Using eucalyptus oil in horse feed at the suggested levels is not anticipated to harm the environment.
  5. Efficacy: Since the Eucalyptus globulus plant and its preparations are already recognized for flavoring food and its role in horse feed would essentially be the same, there wasn’t a need for additional tests to prove its efficacy.

Summary:

EFSA evaluated the use of eucalyptus oil specifically for horse feed. They determined a safe level and found no risks for human consumers or the environment at this concentration. However, direct contact with the oil can cause irritation and potential allergic reactions. Given its existing use in flavoring food, its effectiveness in feed was taken as given.
