Shares of the food company fell as much as 6.1 percent, the most in a single day since October 2016.

Tyson Foods fell the most in roughly 17 months on Monday after China’s retaliatory tariffs on American goods targeted U.S. agriculture and food producers.

Shares of the processed food company closed down 6.2 percent on the quarter’s first trading day amid a broader market sell-off, falling the most in a single day since November 2016. The sell-off in Tyson shares on Monday adds to the company’s nearly 15 percent decline since the year began.

The Springdale, Arkansas company produces and packages chicken, beef, pork and prepared foods, making it a prime target of any agricultural tariffs.
