China’s market regulator has summoned Walmart over food safety issues at Sam’s Club. The move puts the cold chain behind Walmart’s fastest-growing China format under government scrutiny.
What happened: The State Administration for Market Regulation disclosed the summons on June 15, calling in Walmart (China) Investment Co., the headquarters of Sam's Club in China. The review covered both stores and e-commerce, and regulators ordered the company to “prevent food safety risks across the entire chain” and take stronger ownership of food safety. No fine was reported.
Walmart's response: The company pledged it would “regularly report rectification progress to the regulatory authorities.” It also set up a senior-led task force and launched a review across all sales channels and its supply chain.
The exposure: Sam’s Club is the growth engine of Walmart’s China business, accounting for an estimated two-thirds of the unit sales and growing at nearly 23% a year.
Walmart China’s net sales hit $24.6 billion in FY2026, up 23.3% from $20 billion a year earlier, according to the 10-K, though Sam’s Club’s share is not broken out separately. Scaling a fresh, membership-led format at that pace across stores and rapid e-commerce delivery adds more pressure on the cold chain and increases reliance on 3PL and last-mile handoffs. That is where fresh quality tends to break.
The precedent: Foreign retailers have faced this before. The 2014 Husi/OSI scandal forced KFC and McDonald’s to cut ties with Chinese suppliers after authorities shut the plant for selling expired meat, while warehouse-club peers like BJ's brought cold-chain operations in-house to retain control of fresh quality. The question is whether Walmart’s “rectification” stops at audits or changes how supplier and delivery handoffs are structured.
