Traces of antibiotic pesticides in fruits and vegetables may trigger unexpected allergic reactions for people with food allergies, according to a new study published in Annals of Allergy, Asthma and Immunology.
“As far as we know, this is the first report that links an allergic reaction to fruits treated with antibiotic pesticides,” said lead study author Anne Des Roches in a press release.
The study looked at a patient who suffered from anaphylactic shock after eating a blueberry pie, despite not being allergic to any of the ingredients. After weeks of testing with both the patient and a sample of the pie, researchers concluded that the pesticide streptomycin, which is used in orchards, had triggered the reaction.
The use of such pesticides remains legal in the United States, though new Food and Drug Administration regulations may help address the issue, according to the study. The pesticides are illegal in some European countries, Roches said.
