Sweet potato nightmare

My Fiance did our weekly shopping at Makro on Monday and bought some veggies as well. He came home and we put the veggies in the fridge right away. Last night we decided to make the sweet potatoes. As I opened the packet, I felt something on my hand. Looking down I see not only one, but two centipede looking insects about the size of my index finger. They were pink- just imagine how long they have been in there. It was disgusting. I took some photo's and threw the sweet potatoes away. very disappointed in Makro as we are regular customers but now know to never buy veggies from them again
