An ammonia leak in a Virginia commercial building Wednesday night led to 26 people being transported to the hospital, with four of them experiencing "significant symptoms," according to local officials.

Officials in Loudoun County, Virginia, about 45 miles northwest of Washington D.C., received a call reporting a gas leak Wednesday around 8:36 p.m. local time, according to Loudoun Fire Rescue on X, formerly known as Twitter.

The leak occurred at Cuisine Solutions facility, a food processing plant, local outlets including WTOP and WJLA reported.

Fire and rescue crews from multiple area agencies confirmed the leak was ammonia and found "numerous patients who had been exposed," said Loudoun County Fire Rescue in a tweet.
