Chipotle Mexican Grill has pulled jalapenos from restaurants across the country after the peppers were connected to a salmonella outbreak in Minnesota. According to the report, more than 100 people have become ill.

Chipotle is the first restaurant chain publicly tied to the outbreak, but health officials believe the source may not be limited to one company. The peppers linked to the illnesses may also have been served at other restaurants, widening concern beyond Chipotle locations.

The nationwide removal shows how food safety issues tied to a single ingredient can quickly affect large restaurant operators. By taking jalapenos off menus, Chipotle is responding to the investigation while officials continue tracing where the contaminated peppers may have been distributed.

The outbreak has put added attention on salmonella risks in fresh produce and on the supply chains that move ingredients to restaurants. With the investigation still unfolding, the focus remains on identifying the full reach of the affected peppers and limiting any further illnesses.
