Due to the avian flu epidemic, the French government is allowing the agri-food industry to temporarily change the recipes of certain products to address supply issues related to eggs or poultry-related ingredients. This decision is aimed at mitigating the effects of the flu epidemic, which has led to the slaughter of over 19 million poultry and disrupted upstream sectors. These temporary changes may include replacing some duck meat or fat with chicken meat or fat in products like duck rillette, as long as they meet specific minimum requirements. Manufacturers must obtain validation from Fraud Prevention for these modifications, which will be exempted for up to three months, provided they do not pose a risk to consumer safety and the supply difficulties are significant. This measure is part of an effort to ensure the continuity of supply for affected products.
