These are supposedly blood samples of patients and they are been littered on the streets by officials of the Gbagada General Hospital in Lagos.
Facebook user, Bimpe Oseni who shared photos of the alarming sight called the attention of the public to it. She wrote:
My colleague was at Gbagada General hospital with his daughter on Sunday. They drove over a pile of rubbish, out of curiosity, he got out of his car to view the ‘rubbish’. But to his great surprise, the pile of rubbish was actually a collection of lab sample containers with blood in them dumped by the road. He almost passed out. Our General hospitals are gradually turning to death centres. This is the height of wickedness!!! Could someone please pass this on until it gets to the appropriate authorities.
