Some workers at the JBS Louisville pork plant will start a delay for the second day in a row Wednesday following the cyber security attack on the world’s largest meat supplier over the weekend.

The Louisville Butchertown plant said workers in several departments would start two hours late on Wednesday, including the cut floor, which started three hours late on Tuesday.

“This weekend our company was the target of a cyber attack that affected our computer systems,” the JBS Louisville plant said in a Facebook post. “We are continuing to work on the situation and will keep you informed.”

In a statement, the company said the attack affected some of its servers supporting its North American and Australian computer systems.

“The company took immediate action, suspending all affected systems, notifying authorities and activating the company’s global network of IT professionals and third-party experts to resolve the situation,” JBS said in its communicated. “The company’s backup servers have not been affected and it is actively working with an incident response company to restore its systems as quickly as possible.”

JBS USA has closed its nine beef factories, according to Bloomberg, who cited an anonymous United Food and Commercial Workers official. Union officials confirmed this with USA TODAY.

All of the company’s meat-packing facilities in the United States have experienced operational disruptions, union officials said. The union represents more than 25,000 JBS meat processing workers in the United States.

JBS, which is one of the leading processors of beef, pork and other prepared foods in the United States, said it “was not aware of any evidence at this time that a customer’s data , a supplier or an employee have been compromised or misused as a result of the situation. “
