Ghana's disaster management organisation (Nadmo) has admitted that Vice-President Mahamudu Bawumia handed out expired cooking oil to the victims of recent floods in the north of the country.

The oil, which had expired last month, was part of a package of relief items presented by the vice-president.

Nadmo officials say the oil had been isolated in a warehouse and was supposed to have been disposed of, but it was mistakenly added to the relief items when they were being loaded onto a vehicle for distribution.

They are currently in the region to retrieve the expired oil.

Meanwhile, there are reports of people having stomach upsets after consuming the oil.

Nadmo spokesman George Ayisi told the BBC that they are yet to confirm whether their condition is directly linked to consumption of the cooking oil.

Members of Ghana's main opposition party have called for an investigation into how the mistake was made.
