Unpleasant night of horror

Hi Peter, I'm Pontsho Matsapola and my wife Mpho bought chicken polony yesterday, we ate it and our night was unbearable, stomach cramps, pains and lots of dhirrea... This morning when I check the used by date is says 11/04/20. It then jokked my memory back to a month ago when my wife bought pork chops which I later saw it had some yellowish glue kinda like stains on the side and I washed it before braaing and it all went good.
