Safety and efficacy of a feed additive consisting of an essential oil from Cinnamomum cassia (L.) J. Presl (cassia leaf oil) for use in all animal species (FEFANA asbl).
Abstract: Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of an essential oil from leaves, stalks and twigs of (L.) J. Presl (cassia leaf oil) when used as a sensory additive (flavouring) in feed and water for drinking for all animal species. Owing to the presence of styrene in cassia leaf oil, the FEEDAP Panel is not in the position to conclude for long-living animals and animals for reproduction. For 'short-living' animals, the FEEDAP Panel concluded that cassia leaf oil is considered as safe up to the maximum proposed use levels in complete feed of 28.5 mg/kg for chickens for fattening and other minor poultry, 38 mg/kg for turkeys for fattening, 51 mg/kg for piglets and other minor Suidae, 61 mg/kg for pigs for fattening, 100 mg/kg for veal calves (milk replacer), 60 mg/kg for cattle for fattening and other ruminants for fattening, 30 mg/kg for horses, 25 mg/kg for rabbits, 125 mg/kg for salmonids and other fin fish. For the other minor species, the additive is considered as safe at 28.5 mg/kg complete feed. For 'short-living' animals, the FEEDAP Panel considered the use in water for drinking as safe provided that the total daily intake of the additive does not exceed the daily amount that is considered safe when consumed via feed. No concerns for consumers were identified following the use of the additive at the use levels considered safe in feed for the target species. When handling the essential oil, exposure of unprotected users to styrene cannot be excluded. Therefore, to reduce the risk, the exposure of the users should be minimised. The use of the additive under the proposed conditions in animal feed was not expected to pose a risk for the environment. Cassia leaf oil was recognised to flavour food. Since its function in feed would be essentially the same as that in food, no further demonstration of efficacy was considered necessary.

The research investigates the safety and effectiveness of using cassia leaf oil, an essential oil derived from Cinnamomum cassia, as a flavoring additive in food and water supplies for various animal species. The study finds that the oil is safe for short-living animals at proposed levels but has reservations for long-living and reproductive animals due to traces of styrene.
Objective of the Research
The aim of this research was to determine the safety and efficacy of cassia leaf oil as a sensory dietary supplement for various animals.
The research was directed by the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) in response to a formal request from the European Commission.
Research Findings
The experts identified variances in the level of safety for different animals, categorised into ‘short-living’ and long-living/animals for reproduction.
Due to the presence of styrene, a potentially toxic compound, in cassia leaf oil, they could not conclude the oil’s safety for long-living and reproductive animals.
However, they found cassia leaf oil safe for short-living animals at specific maximum levels ranging from 25 mg/kg for rabbits to 125 mg/kg for fin fish.
Consumer Safety and Environmental Impact
They did not find any safety concerns for consumers following the use of the additive at the safe levels indicated for the target species.
Their assessment showed that the additive was not expected to pose an environmental risk when used under proposed conditions.
Handling Precautions and Efficacy
During handling of the essential oil, the exposure of unprotected users to styrene could not be ruled out.
To mitigate this risk, they recommend minimising the exposure of users.
Cassia leaf oil, known to flavor food, served a similar purpose in feed. Thus, they did not find it necessary to further demonstrate its efficacy.
