During our visits to a slaughterhouse in Tamale (Ghana) we witnessed how cattle were falling into uncovered drains, causing extreme suffering, including, cattle breaking their legs and not being able to get back up again. Cattle where than violently dragged to the kill floor by being pulled and dragged by their tails, ears and (broken) limbs.
On our recommendation and with great help from the local NGO, WACPAW, the slaughterhouse filled in the drains, so this terrible suffering is prevented going forward.
