Food allergies affect millions of consumers worldwide1, with the FDA identifying nine major allergens, including peanuts, tree nuts, dairy, soy, and wheat as critical for food safety regulation.
Undeclared allergens are one of the leading causes of food recalls (34.1%) in the U.S.2, making precise and reliable allergen testing essential for food manufacturers, suppliers, and regulatory agencies.
Industry Trends in Allergen Testing
As consumer awareness and regulatory scrutiny increase, the allergen testing market is expected to grow. The global Food Allergen Testing industry was estimated to be worth USD 900.1 million in 2024. It is projected to reach USD 1,909.3 million by 2034, reflecting a CAGR of 7.8% over the assessment period 2024 to 20343.
With stricter global food safety laws, including FSMA (Food Safety Modernization Act) in the U.S. and FSA (Food Standards Agency) regulations in the U.K., manufacturers must ensure their products are free from allergen cross-contamination.
One of the most widely used methods for allergen detection is ELISA (Enzyme-Linked Immunosorbent Assay), known for its high sensitivity and specificity. While advanced technologies such as PCR (Polymerase Chain Reaction) and HPLC-MS (High-Performance Liquid Chromatography-Mass Spectrometry) are emerging, ELISA remains the gold standard for routine allergen screening due to its cost-effectiveness and accuracy4.
Certified Group’s Expertise in ELISA Allergen Testing
At Food Safety Net Services (FSNS) and Certified Laboratories, both part of Certified Group, we specialize in ELISA-based allergen testing at three of our ISO 17025-accredited laboratories in our national lab network: Aurora, Ill.; Melville, N.Y.; and San Antonio, Texas.
Our ELISA allergen testing capabilities allow us to detect allergens at low parts per million (ppm) levels, ensuring compliance with regulatory standards. We provide testing for priority allergens, including gluten, milk, egg, peanut, soy, and others in processed food and raw ingredients.
Additionally, we conduct cross-contamination risk assessments and offer routine batch monitoring and validation to ensure food safety and compliance.
Why ELISA is the Preferred Choice for Allergen Testing
- High Sensitivity & Specificity: ELISA can detect allergens at trace levels, ensuring food safety.
- Regulatory Compliance: Approved by the FDA, USDA, and other global agencies for food safety testing.
- Cost-Effective: Compared to PCR and HPLC-MS, ELISA offers a faster and more economical approach for routine allergen screening3.
- Reliable for Various Food Matrices: ELISA is highly effective for detecting allergens in processed foods, beverages, and raw ingredients.
The Future of Allergen Testing & Our Commitment
While PCR and HPLC-MS offer alternative allergen detection solutions, ELISA remains the most widely accepted method due to its balance of sensitivity, ease of use, and cost.
Certified Group companies continually monitor industry advancements and adapt our methods to ensure accurate, fast, and cost-effective allergen testing for our clients. Our goal is to provide food manufacturers, retailers, and suppliers with confidence in their allergen control programs, ensuring compliance and protecting consumers from potentially life-threatening reactions.
