From Serious Eats:
"The USDA has introduced a new certification for extra-virgin olive oil, called the Quality Monitoring Program. The QMP verifies the purity and quality of the olive oil, and conducts rigorous tests and inspections to ensure that the certification standards are upheld by producers. The first company to receive the QMP logo, Pompeian Inc. in Baltimore, imports olive oil from the Mediterranean region and South America. The company's oils will begin carrying the QMP logo later this month."
