Philippine officials tucked into servings of lechon, the popular dish of roasted whole pig, in front of television cameras on Thursday to reassure the public of the safety of the national staple meat after the discovery among hogs near Manila of a strain of the Ebola virus.

Arthur Yap, agriculture secretary, and Francisco Duque, health secretary, said the Ebola Reston virus, which had never been found in pigs before, presented a low health risk for humans and was different from the deadly African variety.
