There have been no factory shutdowns or layoffs this spring, but the coronavirus has left a deep mark at Philadelphia Macaroni Co., the family-owned Bella Vista-based business that doubled in size this week to 700 million pounds a year after buying rival A. Zerega’s Sons of New York.

“Oh my God, we’re going 24/7. We’re putting up ‘Help Wanted’ billboards out West," says Linda Schalles, special-projects director for the company, which employs more than 400 at offices on South 11th Street, and factories in Warminster and Harrisburg, Pa.; Minot, N.D.; Grand Forks, N.D.; and Spokane, Wash. "And we’ve been on it, with masks and washing, from the very beginning. This has to be a very clean business.”
