A Minnesota woman says she fainted, spiked a 102-degree fever, and was hospitalized with sepsis three days after eating a chicken burrito bowl at a Chipotle in Roseville, and genetic testing connected her case to a multistate outbreak, according to a lawsuit filed Tuesday.

Chipotle stock has fallen 6% as of Tuesday afternoon.

Chipotle has not been officially linked to the outbreak and removed jalapeños from some stores “out of an abundance of caution.”
