Quote from article: “On Sept. 15, the department issued a new waiver preventing school meal programs from being financially penalized if they fail to meet the guidelines because of supply-chain issues.”

My thoughts/interpretation: When you mess with a supply chain you cut off the ability to efficiently do business, because a company will not receive it’s supplies. That cause a lack of commerce and goods that are being distributed.
