the length of time during which Newcastle disease may have existed on the holding or in the pigeon house;
the possible origin of the Newcastle disease on the holding or in the pigeon house and the identification of other holdings or pigeon houses in which there are poultry, pigeons or other birds kept in captivity which may have become infected or contaminated from the same source;
the movement of persons, poultry, pigeons or other birds kept in captivity or other animals, vehicles, eggs, meat and carcases and any implement or substance likely to have carried Newcastle-disease virus to or from the holding or pigeon house in question.
