This horrifying footage shows rats crawling around in shopping trolleys in a Tesco car park. A mother, who did not wish to be named, was taking her children to do the weekly shop when she saw the rodents scuttling around. Disgusted in what she saw, the 36-year-old filmed the footage, which shows three rats rummaging for food. She posted the video on social media which attracted disgust from those who shop at the Tesco in Pitsea, Essex where the footage was filmed. The gobsmacked mum-of-two, of Basildon, Essex, said: "I had just come out of Tesco with my four-year-old twins and as we were walking to the car we saw a little nest of what I thought to be mice running around.
