(e)persons other than keepers of the birds must be prohibited from having access to areas where susceptible birds are kept;
(f)the keeper of susceptible birds must take appropriate biosecurity measures in such areas and when entering and leaving such areas;
(g)such other requirements as the National Assembly considers necessary to reduce the risk of transmission of avian influenza from wild birds to susceptible birds in zoos.
