MINNEAPOLIS — Activists plan to gather at 11 McDonald’s restaurants around Minnesota on Tuesday to protest the use of pesticides on potato fields in Minnesota owned by a major supplier to the fast-food chain.

The action is being organized by the Pesticide Action Network and the Toxic Taters Coalition, and includes about two dozen events nationwide. Organizer Lex Horan says the protests are timed to coincide with McDonald’s all-day breakfast menu launch but is targeted at Fargo, North Dakota-based R.D. Offut Co. Horan says Offutt sprays too much pesticides on its crops, and that the chemicals sometimes drift over residential areas in central Minnesota.
