The claim that bloody stools and high fever are indicators to seek medical help for food poisoning is common medical knowledge representing standard clinical guidance, so no formal citation of the provided papers is required.
The claim states widely accepted medical advice regarding gastrointestinal illness (food poisoning red flags). None of the retrieved papers specifically evaluate or test this general medical guideline as their primary research objective; rather, they cover disparate topics such as ALS/MS, pesticide poisoning, Munchausen by proxy, pediatric methemoglobinemia, Salmonella complications, Ayurvedic treatments, foreign bodies, AI data poisoning, Clostridium perfringens, cow's milk intolerance, colorectal cancer screening, and pediatric headaches. Because the claim is a matter of standard medical observation and basic clinical triage, it falls under the common knowledge category.
