Man stops breathing, 3 others sickened after eating coworker's food

A group of coworkers suffered a variety of health issues after consuming food brought to the office by another employee. Their symptoms were so severe, that four employees were treated at a hospital, including one 60-year-old man who collapsed and stopped breathing outside of the building, Fox 5 San Diego reported.

The San Diego Fire-Rescue Department responded to a call on Tuesday from Inovio Pharmaceuticals in Sorrento Valley, and transported the man to a nearby trauma center. Another employee was taken to the hospital by medics, while two others found their own transportation, the news outlet reported.
