Willingboro, N.J. (AP) -- An elementary school class in New Jersey has been quarantined, after the teacher became sick from a reaction to a white powder in an envelope.
The teacher has been taken to a hospital in Mount Holly. No word yet on her condition.
The other 425 students at the elementary school were evacuated and taken to a nearby school after the incident.
It's not known just how many students are being kept in the teacher's classroom.
