The company's poultry processing plant in Saraburi province will be shut from Sunday to Thursday, the company said in a statement. Operations at its 18 other food-processing and feed factories will remain normal, it said.

Out of 5,800 workers at the closed plant, 245 have tested positive, while others are still waiting to be tested or to receive test results, said the Saraburi provincial administration.

Thailand has reported 154,307 coronavirus cases since last year, with total casualties topping 1,000 on Sunday.

On Friday, Sri Trang Gloves Pcl also closed glove factories in Trang and Surat Thani provinces for three days from Friday, after dozens of workers tested positive.

Earlier this month, Cal-Comp Electronics Thailand Pcl closed a factory in Phetchaburi province for 14 days until this coming Thursday to stem infections among its workers.
