Hi, I've just prepared my sons sandwiches for tomorrow now worried if it's ok? I purchased a packet of thinly sliced cooked chicken from M&S this afternoon, some of the slices look slightly pink, and there is a few little red specks I've picked the clearest of the meat & made the sandwiches but I'm worried. Don't want to make him ill, yet part of me feels I should be able to trust M&S Any advice please x
