What are the symptoms of melamine poisoning?
Wang says symptoms of melamine poisoning are related to kidney stones or bladder stones. “Infants with these kinds of problems will have severe abdominal pain, blood in the urine, and/or difficulty urinating,” Wang says. “If you are not seeing that, there is no need to think the child has suffered any ill effect from his or her formula.” According to the American Society of Pediatric Nephrology, signs and symptoms of melamine poisoning in infants include: • Unexplained crying in infants, especially when urinating • Vomiting • Unexplained fever due to urinary tract infection caused by urinary obstruction • Blood in the urine • Stones discharged while passing urine • Signs of kidney infection • High blood pressure • Flank pain • Kidney failure SOURCES: Mendoza, M. and Pritchard, J.
