Good day i have been very ill in 2 occasions after eating red meat. i suffer from diarrhoea, nausea, loss of appetite, stomach cramps that last the whole day. it feels like i had food poisoning. what could be the cause?

Many possibilities including, but not limited to, food poisoning, lactose intolerance, specific protein allergic reaction, coincidental viral or bacterial infection, etc. To provide effective treatment, the cause of your distress must first be determined. For an accurate diagnosis you must see your General Practitioner or a specialist Gastroenterologist.
