(Des Moines) – A major meat processing company in Iowa suffered a cyberattack over the weekend. According to KCCI, JBS USA confirms the attack hit some of its North American and Australian IT systems Sunday. The company suspended all systems that were affected. It’s not clear if the attack is having any kind of effect on production since the company’s backup systems were not hit.

JBS says it is not aware of any evidence that would indicate its data has been compromised. Company officials say there may be delays in some transactions. JBS has processing plants in Marshalltown, Ottumwa and Council Bluffs.
