Cyclospora Outbreak Dulls Salad Dressing Sales After World Cup Boost
A stomach illness made many people worry that leafy greens were unsafe.
The illness is called cyclosporiasis and can come from contaminated food.
Health officials connected an early group of cases to iceberg lettuce at some Taco Bell restaurants.
Many people stopped eating salads, even after officials said leafy greens were safe again in Michigan.
Because people bought fewer salads, they also bought less salad dressing.
Kraft Heinz and Clorox both saw dressing sales decline.
Some shoppers bought frozen vegetables and fruit instead, especially frozen kale.
Analysts expect shoppers to slowly regain trust, but the companies could still lose sales this quarter.
Kraft Heinz salad-dressing sales fell 20% in the latest four weeks, while Clorox’s Hidden Valley Ranch declined 5%.
Consumers reduced salad and leafy-green consumption after thousands of Americans developed cyclosporiasis.
Health officials linked an initial Midwest infection cluster to iceberg lettuce served at Taco Bell locations.
Iceberg lettuce sales fell 20%, while frozen kale sales rose 14% in the latest reported periods.
Analyst Robert Moskow said continued declines could weigh on Clorox and Kraft Heinz’s quarterly sales.
