Labeling regulations in the European Union require mandatory labeling of certain ingredients, and allow voluntary labeling, termed Precautionary Allergen Labeling (PAL) for "may contain" statements to account for product ingredients included as inadvertent, trace amount or cross-contamination during production. PAL labeling may be confusing to consumers, possibly due to variations of wording on labels. The European Union initiated a process to create labeling regulations for unintentional contamination, although it may not be official until 2024. The US FDA requires reporting by government inspectors and manufacturers to reduce or eliminate the potential cross-contact of product ingredients, including soy, and to state possible cross-contamination on food labels, using the words "may contain".
