French goose liver producers are set to increase the price by 10% due to rising cereal prices for duck feed and increased packaging costs. The pandemic's impact on the industry, including the closure of restaurants, the largest market, and bird flu outbreaks leading to the culling of 3.5 million poultry, have also contributed to the increased costs. Grain prices have surged due to concerns about global supply shrinkage, and the French poultry feed index rose by 22% in the first three months of the year. The price increase will affect both domestic and international markets, including France's largest consumer, the United States.
