You’ve probably seen them on food packaging: May contain peanuts. Manufactured in a facility that also processes tree nuts. Made on shared equipment.

These statements, known as Precautionary Allergen Labels (PALs), are intended to alert consumers to the possibility of unintended allergen cross-contact. But here’s what many people don’t realize: these labels aren’t standardized in the United States, and they don’t tell consumers how much risk actually exists.

U.S. law requires manufacturers to declare major food allergens that are intentionally included in a product’s formulation. In contrast, precautionary allergen statements such as “may contain” or “made in a facility with” are voluntary and are used to communicate the potential for unintended cross-contact.

For people managing food allergies, that uncertainty can be frustrating. Understanding what PALs mean (and what they don’t) can help consumers make more informed decisions while highlighting an important reality: labels communicate risk, but allergen management practices determine it.

What Precautionary Allergen Labels Really Mean

While manufacturers are required to disclose intentionally added major food allergens, the FDA does not regulate when precautionary allergen statements should be used, what wording manufacturers should choose, or what level of cross-contact risk must exist before a label is applied.

This leaves significant room for individual manufacturer judgment. As a result, one manufacturer can choose to use a “may contain” statement out of an abundance of caution, while another with similar manufacturing practices can choose not to use one at all. The presence of a PAL doesn’t necessarily indicate a high level of risk, and the absence of one doesn’t guarantee a product is free from allergen cross-contact.

Because precautionary labels are voluntary and applied inconsistently, MenuTrinfo® takes a different approach. For example, Certified Free From™ products cannot carry precautionary allergen labels, nor can they contain ingredients that carry PALs. Similarly, MenuTrinfo®’s restaurant allergen reports focus on known ingredients and preparation practices rather than relying on precautionary statements that may be applied inconsistently.

The conversation around PALs is also evolving globally. In 2026, the Codex Alimentarius Commission adopted new international guidance encouraging a science-based, risk assessment approach to precautionary allergen labeling with the goal of making these statements more meaningful and consistent for consumers.

Managing Risk Beyond the Label

Whether a product carries a precautionary statement or not, the most important factor is how allergens are managed throughout production and food preparation.

In food manufacturing facilities, Good Manufacturing Practices (GMPs) require sanitation procedures designed to reduce the risk of allergen cross-contact. These cleaning and operational controls are reviewed as part of facility oversight and are expected regardless of whether a product carries a precautionary allergen label. A PAL should never replace strong allergen control procedures.

Restaurants present a different challenge because they don’t have the same level of process control found in manufacturing facilities. Unlike highly controlled manufacturing environments, commercial kitchens are fast paced, constantly changing, and often preparing dozens of menu items at the same time. Shared grills, fryers, cutting boards, utensils, and preparation surfaces all create opportunities for unintended cross-contact if proper procedures aren’t consistently followed.

That’s why ingredient information is only one piece of the puzzle. Equally important are employee training, standardized preparation procedures, clear communication, and a culture that prioritizes food allergy safety every day.

Building Confidence Through Better Allergen Management

For consumers, precautionary allergen labels can be helpful; but they shouldn’t be the only factor used to evaluate food allergy safety. A “may contain” statement doesn’t automatically mean a product is unsafe, just as the absence of a precautionary allergen label doesn’t guarantee there’s no risk. The organizations that inspire the most confidence don’t rely on labels alone. They invest in comprehensive allergen management programs, employee education, verified processes, and continuous improvement to reduce the risk of cross-contact at every stage.

At MenuTrinfo®, we believe food allergy safety starts with understanding risk; not simply reacting to a label. Through training, certification, allergen analysis, and consulting, we help food manufacturers, restaurants, colleges, and other foodservice organizations build comprehensive allergen management programs that create safer dining experiences and greater confidence for the people they serve.
