Singapore Airlines has said it will require all crew members to be vaccinated against anthrax.
It said the move was being made to “protect passengers from a potential risk of exposure to anthrax while onboard its aircraft”.
The carrier has no known cases of anthrax and said that a dangerous strain of the bacteria was not likely to be present on its planes.
Singapore bans and bars certain animals, insects and the quarantine of others, over fear they can carry pathogenic bacteria.
However, inspectors from the city state’s food inspection authority said this week that they were unifying their approach to unpurchased species.
The step is intended to help establish common protocols to make authorities on the ground and the airport more informed of the status of the ban when such species are brought into the country.

The airline said passengers were not at risk, but it was responding to customers’ concerns about the immunisation, which is normally done after an infectious disease is confirmed.
“As a precautionary measure, all passengers on a Singapore Airlines aircraft will be required to undergo a background medical screening,” the airline said in a statement.
