Salad chains see foot traffic drop amid cyclosporiasis fears

Foot traffic to salad-focused chains in the United States has declined sharply following news of a cyclospora outbreak linked to contaminated lettuce. Data from Placer.ai shows drops of 7.1 per cent at Chopt, 7.4 per cent at Panera Bread, and 3.1 per cent at Sweetgreen on Sunday, 11 July, compared to 2026 averages. While none of these chains have been linked to the outbreak, which may have sickened nearly 7,000 people, Sweetgreen shares fell 23.3 per cent over five days. Taco Bell, the only chain with suspected links, saw traffic down 5.8 per cent nationally and 11.5 per cent in Michigan, where 4,312 cases have been recorded.

The decline in visitor numbers began around 10 July, according to Placer.ai, which noted that customers were actively avoiding establishments with lettuce-heavy menus. Conversely, quick-service chains such as McDonald’s, Chick-fil-A, and Wendy’s saw a 0.8 per cent increase in foot traffic on the same day. Fast-casual chains overall experienced a 2.4 per cent drop in foot traffic, reflecting a broader consumer shift away from fresh produce amid the health crisis.

Wall Street has reacted swiftly to the market volatility. Sweetgreen shares fell 23.3 per cent over five days, while Yum Brands, the parent company of Taco Bell, saw its shares drop 7.2 per cent over the same period. Chopt and Panera Bread remain privately traded, limiting direct public market exposure, though their operational metrics indicate significant consumer pullback. Federal authorities have not yet identified a specific ingredient, grower, or supplier as the cause, though Michigan’s Health and Human Services department has described lettuce or salad greens as a potential source.

Taco Bell faces the most direct operational impact as the only chain with suspected links to the outbreak. Some locations in the Detroit region posted notices suspending sales of lettuce, cilantro, onion, pico de gallo, and guacamole due to a nationwide recall. The Washington Post reported that health officials are investigating whether the chain played a role in the outbreak. In Michigan, where the case count has reached 4,312, Taco Bell’s foot traffic was down 11.5 per cent compared to the Sunday average.

Despite the widespread anxiety, consumer behaviour remains mixed. Two customers in Manhattan’s Financial District told WIRED they had not heard of the outbreak, with one visitor to Chopt stating she “didn’t even think about” the risk. New York City cases represent a threefold increase over last year at this date, according to the local health department, yet the city has far fewer total cases than Michigan, with 510 cases recorded in 2026.
