Background: The current standard of care for managing peanut allergy includes avoidance of peanut and use of injectable epinephrine; however, strict avoidance is difficult and accidental ingestion is common with potentially serious consequences. Despite vigilance and efforts to minimize the risk of accidental exposure, peanut protein cross-contamination continues to occur in a variety of foods, including baked goods., Objective: To assess and quantify the presence of peanut protein contamination in certain baked goods., Methods: Randomly selected baked goods were collected from bakeries in the New York and Miami metropolitan areas that sold a variety of ethnic cuisines. A second set of samples from the same bakeries was collected at least 1 week after to evaluate between-batch variability. Samples were sent to the Food Allergy Research and Resource Program to analyze peanut contamination by enzyme-linked immunosorbent assay. Consumption estimates were based on 2003 to 2010 National Health and Nutrition Examination Survey survey data., Results: Of 154 samples from 18 bakeries, 4 (2.6%) had detectable peanut contamination with peanut protein levels ranging from 0.1 mg/100 g to 650 mg/100 g. Consumption estimates for single occasion ingestion of a contaminated item ranged from 0.07 mg to 832 mg of peanut protein., Conclusion: In this study, unintended peanut protein was present in a small, but not insignificant, proportion of baked goods, with the potential to trigger a reaction in individuals with peanut allergy. Some products contained high levels of unintended peanut protein. The current data support the potential for accidental exposure to peanut protein with its associated risk., (Copyright © 2022 The Authors. Published by Elsevier Inc. All rights reserved.)

Background: Peanut allergy (PA) affects approximately 1.6 million US children. The current standard of care is strict avoidance and prompt reaction treatment. Peanut allergy health care costs and health care resource utilization (HCRU) are poorly understood., Objective: To estimate PA health care costs and HCRU using a nationally representative commercial payer database., Methods: The IBM MarketScan Commercial Claims and Encounters Database was examined for PA diagnosis/reaction codes between January 2010 and October 2016 in patients 64 years of age or younger, with age cohort-matched controls. Outcomes were measured 12 months before and after the first claim date. Health care costs and HCRU were compared using Student's t tests and χ 2 tests., Results: Patients with a PA-related diagnostic code (n = 41,675) incurred almost double all-cause health care costs vs controls ($6436 vs $3493, P < .001), mainly from inpatient and outpatient medical costs ($5002 vs $2832, P < .001). More than one third of the PA group patients (36%) had a code indicative of an anaphylactic reaction during follow-up. Mean PA or reaction-related code costs per visit totaled $7921 for hospitalizations and $1115 for emergency department (ED) visits. Costs were 30% lower in patients with asthma codes without PA codes vs those with both codes ($5678 vs $8112, P < .001); all-cause ED costs were more than double in patients with atopic dermatitis codes with PA codes vs those without PA codes ($654 vs $308, P < .001)., Conclusion: National commercial payer claims data indicate a significant health care burden associated with a PA-related code, including over $6400/patient in annual all-cause costs and increased health care utilization., (Copyright © 2020.
