Pennsylvania’s mushroom industry is divided over a federal trade ruling that could reshape competition with Canadian growers and affect grocery store prices.
Earlier this month, the U.S. Department of Commerce issued a preliminary finding that some Canadian mushroom producers were selling products in the United States at unfairly low prices. If the agency’s decision is upheld in September, new anti-dumping and countervailing duties could increase the cost of imported Canadian mushrooms by an estimated 10% to 15%.
Many Pennsylvania growers, particularly members of the Fresh Mushrooms Fair Trade Coalition, welcomed the ruling, arguing it would help level the playing field for domestic farms struggling with declining sales and rising labor costs.
Pennsylvania produces more than two-thirds of the nation’s mushroom crop, with most production centered in Chester and Berks counties. But the industry has faced mounting pressure in recent years. U.S. mushroom production has declined from a peak of 811 million pounds in 2015 to 631 million pounds in 2025, while fresh mushroom imports, primarily from Canada, have more than doubled since 2012 to 208 million pounds last year.
Coalition members say at least 10 U.S. mushroom farms, including six in southeastern Pennsylvania, have closed since 2022 as Canadian imports captured a growing share of the shrinking market.
Not all growers support the federal action, however. Kennett Square-based South Mill Champs, which operates mushroom farms in the United States, Canada and Mexico, contends the investigation unfairly compares premium U.S. mushrooms with lower-grade Canadian products. Company officials argue that Canadian producers have gained market share through newer facilities, greater efficiency, and investments in automation rather than through unfair pricing.
Beyond trade concerns, growers on both sides agree the industry continues to grapple with labor shortages. Mushroom harvesting remains labor-intensive, and employers say obtaining legal workers has become increasingly difficult amid tighter immigration enforcement.
South Mill Champs says labor challenges have slowed its plans to expand production in the United States, including a proposed automated mushroom farm in Chester County. Many growers believe that increased automation, combined with reforms to the agricultural workforce, will be essential to the industry’s long-term future.
The Commerce Department is expected to issue its final decision in September, determining whether the preliminary duties become permanent.
