As the most common food allergy, milk allergy affects millions, including 2.5 percent of children under age 3. While some kids outgrow it, others’ life-threatening response to dairy products never subsides.
Nine-year-old Ludovica La Rosa was born into an Italian family but until recently was never able to indulge in favorites like lasagna or pizza because of a life-threatening dairy allergy. Her allergy was so severe that the tiniest trace of milk, found in a piece of cured ham, once sent her into shock.
“Her lips were swelling like crazy,” Ludovica’s father, Gregorio La Rosa, recalled of the family’s trip to the emergency room. “The same thing happened to the mucous membrane in her throat. It was really, really scary.”
