Rotten food

Pick ‘n Pay canal walk branch always has something rotten! If it’s not spoiled eggs or eggs infested with maggots once you open the package, today I opened a litre of milk from a box I bought just about a month ago and even that was spoiled. Poured out as per normal but once heated up it became thick. Warmed up some more to make sure it wasn’t the porridge the first time around but the same thing happened. 3 weeks ago we bought a big pocket of onions at Pnp Howard centre and half of the pack was off! Onions were brown and slimy once cut open!
