Locally, they found that a third of the food vendors at Lincoln Financial Field had at least one major safety violation, 29-percent of those at Citizens Bank Park and 15-percent at the Wachovia Center had violations.
None of the professional venues in Chicago had major infractions but 72-percent of the vendors at the new Dallas Cowboys stadium did.
Health inspectors say one of the most troubling violations was food temperature. When food is at improper temperatures that's when dangerous bacteria can grow, if consumed that can bring on nausea, diarrhea and vomiting.
Some examples of other major or critical violations include cross contamination, employee hygiene, kitchen equipment and rodent/insect contamination.
