While carrot allergy is often associated with fresh produce, a 2024 investigation by the Food Allergy Research & Education (FARE) organization revealed that processed foods frequently contain hidden carrot derivatives, posing risks to unsuspecting consumers. Carrot pulp, juice concentrate, and even carrot-based natural colorings (e.g., beta-carotene) are increasingly used in soups, sauces, baked goods, and plant-based meat alternatives—often without clear labeling.
The report highlighted cases where individuals with known carrot allergies experienced reactions after consuming products like vegetable broths, “natural” snack bars, and vitamin supplements. Unlike major allergens (e.g., peanuts or milk), carrots are not required to be highlighted on labels in many countries, leaving gaps in consumer protection.
In response, advocacy groups are pushing for regulatory changes. The European Food Safety Authority (EFSA) is reviewing a proposal to classify carrots as a “priority allergen,” which would mandate bold labeling. Meanwhile, the U.S. FDA has issued draft guidance encouraging—but not requiring—manufacturers to disclose carrot ingredients more transparently.
Food scientists are also exploring solutions. A team at the University of Copenhagen is developing a method to detect trace carrot proteins in complex foods using mass spectrometry, which could improve allergy testing accuracy. Another focus is promoting alternative natural colorings, such as beetroot or spirulina, to replace carrot-derived additives.
For consumers, experts advise scrutinizing ingredient lists for terms like “natural flavors” or “vegetable blend” and contacting manufacturers when in doubt. Allergists stress the importance of updating allergy action plans to account for hidden exposures, especially for children, who may outgrow other food allergies but retain sensitivity to carrots.
The findings underscore the need for collaboration between allergists, policymakers, and the food industry to close labeling loopholes and protect vulnerable populations. As plant-based diets grow in popularity, vigilance against hidden allergens will become even more critical.
