Summary

In the United States, Sweetgreen, a salad-centric restaurant chain, has faced significant challenges due to health concerns surrounding its food products. On August 7, 2026, the company reported a 10% drop in its stock price as consumers began to avoid its salads amid fears of a cyclospora outbreak. This outbreak has been linked to fresh produce, causing widespread concern among diners. Sweetgreen's earnings report revealed a drastic reduction in its full-year forecast, projecting an adjusted loss of $27 million to $23 million, a stark contrast to its previous estimate of $1 million to $6 million.

The company also indicated that its same-store sales could decline by 7% to 8% this year, worsening from an earlier forecast of a 2% to 4% decline. This downturn in sales is attributed to reduced consumer demand for fresh prepared foods, which Sweetgreen acknowledged in its statement regarding the multistate outbreak of cyclosporiasis that began in mid-July. The company has not been directly linked to the outbreak, yet the fear of contamination has significantly impacted its business.
