Would-be epidemiologist and school principal Agnes Camacho figures it was the school breakfast of egg salad and melon that made almost 300 students ill at Marcial A. Sablan Elementary School in Guam.

Sablan told PNC News, "At around 9:45 several students came into the office complaining about stomach aches and they were vomiting and then another 15 minutes several more came in and we said that’s a high number right so we started documenting their vomiting and stomach aches and then another fifteen minutes they were just coming in students were coming in we had a total of 102 students who were registered with the vomiting.”

Anxious parents flooded the schools with phone calls while others came in person to find out if their children had been sent to the hospital.

At Marcial Sablan elementary school hallways were lined with vomit, "It’s just very scary the hallways here this wall this wall behind and both sides were filled with students sitting and then in the nurses office also… and each of them had trash bags and they were all vomiting,” said Camacho.

The food was outsourced from King’s Restaurants. According to Principal Camacho, Public Health arrived and took a sample of the food for testing.
