A cyclospora outbreak linked to shredded lettuce at Taco Bell in July 2026 caused a sharp drop in customer traffic, with daily visits falling over 18% by July 15 and nearly 31% on July 17. The CDC tied at least 1,947 illnesses and 98 hospitalizations across nine states to the outbreak, with no deaths. The contaminated lettuce was traced to Taylor Farms de Mexico and recalled. Despite the crisis, Yum! Brands reported strong Q2 earnings on July 30, beating expectations with adjusted earnings of $1.62 per share and revenue up 12% to $2.17 billion. Management indicated the worst sales damage had passed, leading the stock to rise over 3% on earnings day after an initial 5-8% decline since the outbreak began.
