Milk was a “bad choice” for Justin Bieber, who blamed it for making him vomit onstage Saturday night in Arizona, but it’s an even worse choice for the 1.3 million children who have  milk allergies. New Zealand researchers say they’ve found  a way to genetically engineer cows to produce  hypoallergenic milk, but others say that’s too good to be true…Immediate symptoms of milk allergies can include hives, wheezing and vomiting, according to the Mayo Clinic. Symptoms that take longer to develop may include diarrhea, abdominal cramps, a skin rash around the mouth and a runny nose.
