On Sunday, July 11, as information of a large cyclospora outbreak—probably linked to contaminated lettuce—made headlines, site visitors at Chopt fell by 7.1 %, in comparison with the chain’s common Sunday site visitors in 2026, in accordance with Placer.ai information. The identical day, foot site visitors at Panera Bread was down 7.4 %, and Sweetgreen was down 3.1 %, in comparison with these chains’ Sunday averages.

Two clients exterior of a Sweetgreen location in Manhattan’s Monetary District informed WIRED on Thursday that they hadn’t even heard of the cyclospora outbreak. New York has far fewer circumstances than Michigan, with 510 circumstances up to now in 2026. Greater than 380 are in New York Metropolis, although, which represents a threefold improve over final 12 months at this date, in accordance with the native well being division.
