To qualify, the two types of poultry must make up at least 70% of the poultry block, defined as the entirety of poultry ingredients, not the entire product, as is often assumed. Also, neither of the two types of poultry can, when considered separately, constitute less than 30% of the poultry block. If the two types of poultry meet these requirements, they may be linked by the word "and" in the ingredient statement, and the order of predominance can change without forcing a label change.
USDA has expanded its so-called "70-30 rule" for meat labeling to apply to poultry, as well. That means no label changes are necessary when two types of poultry ingredients are present in processed foods in slightly varying amounts.
