In April 1994, the largest outbreak of botulism in the United States since 1978 occurred in El Paso, Texas.
Thirty persons were affected ; 4 required mechanical ventilation.
All ate food from a Greek restaurant.
The attack rate among persons who ate a potato-based dip was 86% (19/22) compared with 6% (11/176) among persons who did not eat the dip (relative risk [RR]=13.8 ; 95% confidence interval [CI], 7.6-25.1).
The attack rate among persons who ate an eggplant-based dip was 67% (6/9) compared with 13% (24/189) among persons who did not (RR=5.2 ; 95% CI, 2.9-9.5).
Botulism toxin type A was detected from patients and in both dips.
Toxin formation resulted from holding aluminum foil-wrapped baked potatoes at room temperature, apparently for several days, before they were used in the dips.
Consumers should be informed of the potential hazards caused by holding foil-wrapped potatoes at ambient temperatures after cooking.
