What would happen if a person ate food that has fly eggs?

Yesterday evening at work, there was a box of the school lunch meal that was left on the office desk. It was chinese and I had some at lunchtime and it tasted really good, so when I saw the other box there in the evening, I asked if I could eat it. The secretary said ok. When I opened the box, I inspected the food and saw that it had about four clusters of fly eggs around the meat in the food. I immediately told the secretary about it and I threw it away. I was just wondering what would have happened if I ingested the food. Would I have to go to the E.R?
