Simplot Plans Mouscron Potato Plant Shutdown as European Capacity Outruns Demand

Simplot owned Clarebout Potatoes has begun a Belgian information and consultation process over a plan to reduce and then halt production at its Mouscron frozen potato plant. Employees were sent home on September 7, 2026, and were told the following day that the site faced a phased shutdown, according to reporting from Le Monde based on the company and worker representatives.

The plant, operating near the French border since 1988, employs 392 people, about 60 percent of them French nationals. Production resumed on September 9, but the consultation means the plant's longer term status, the timing of any closure and the employment consequences remain subject to the formal process.

Clarebout attributed the plan to the age of the Mouscron facility and to persistent pressure in frozen potato products, including overcapacity, stronger competition and rising costs. The company said its production capacity was about 14 percent to 20 percent above anticipated demand, a range that makes the decision a capacity correction rather than simply a local maintenance issue.

The proposed shutdown comes roughly a year after J.R. Simplot completed its acquisition of Clarebout. Simplot said that transaction added five European locations, lifted its global food production network to 23 facilities and gave the privately held U.S. agriculture and food group a larger European frozen potato footprint.

Mouscron therefore tests the industrial logic of that expansion. A broader network can improve customer reach and local supply, but it also exposes overlapping or less competitive assets when demand falls short of installed capacity. The consultation will show how Simplot intends to balance European coverage with plant utilization.

The decision also reaches beyond factory employment. Potato growers in northern France and Belgium depend on processors for contracted outlets, while the 2026 drought has left some crops smaller and more difficult to meet strict specifications for size, dry matter and sugar content. Losing processing capacity could tighten options for farms already managing weaker yields.

Competitive investment is moving in the opposite direction nearby. McCain is spending €300 million to modernize its French production facilities, including sites around 50 kilometers from Mouscron. The contrast points to a regional reset in which capital is moving toward plants judged efficient enough for a more competitive frozen foods market.

The next confirmed milestones are the outcome of employee consultation, a definitive production timetable and any plan for workers, equipment or volume to move elsewhere in the Clarebout network. Until those steps are settled, the shutdown should be treated as a company plan under consultation, not as a fully completed closure.
