Don't do it again : You might get food poisoning symptoms within an hour like belly pain, nausea, vomiting and diarrhea. If this occurs, drink plenty of fluid and come seen a doctor. More severely, anaerobic bacteria grows inside the sealed package. If this is the case, you mild have severe diarrhea and that can be dangerous. This takes hours to days. You need to see a doctor if those occur. Don't do it next time.
