Pesticides in Tap Water and Food Linked to Food Allergies

New research in Annals of Allergy, Asthma & Immunology examines ”the association between exposure to environmental pesticides represented by dichlorophenols and allergic sensitization measured by allergen-specific serum IgE levels.” The study found “sensitizations to 1 or more food allergens were more common in those with exposure to 2 dichlorophenol metabolites. After multivariable adjustment, urine dichlorophenol levels at the 75th percentile and above were associated with the presence of sensitization to foods (odds ratio, 1.8; 95% confidence interval, 1.2-2.5; P = .003).”
