Mexico has blocked imports of chicken from Foster Farms plants in Livingston and Fresno linked to a salmonella outbreak.
According to the Los Angeles Times, the Mexican government told the U.S. Department of Agriculture on Tuesday that it was removing the three plants from its list of approved exporters.
The plants are tied to a salmonella outbreak that has sickened at least 338 people across the U.S. since March.
Mexico is the top destination for U.S. poultry exports, valued at $1 billion last year, the Times said.
But the vast majority of Foster Farms’ business is domestic, the newspaper said, with exports accounting for no more than 7% of its annual revenue of $2.3 billion.
