A cloud of habanero chile powder sent one woman to a hospital and hazardous materials crews to a Las Cruces industrial park.
Workers called 911 around 7:45 p.m. Wednesday complaining of irritated eyes, sore throats and bloody noses.
New Mexico State Police say a hazmat crew and emergency personnel responded to the scene.
Officials determined that habanero chile particles lingered in the cold evening air after employees finished their work, then went into ventilation systems.
