Bad news for lovers of spicy Mexican cuisine: Salsa and guacamole are emerging as some of the fastest-growing causes of foodborne illness, according to a study released Monday by the Center for Disease Control and Prevention (CDC).
Between 1998 and 2008, there were twice as many foodborne outbreaks associated with salsa, guacamole and pico de gallo than there had been in the previous decade, CDC found.
Researchers named several possible factors behind the jump. Salsa and
guacamole are often made in large batches, so even a small
amount of contamination could affect many people; they tend to sit
outside of refrigerators for long stretches of time; and they're both
made with raw ingredients, including tomatoes, jalapeno peppers and
cilantro, all of which have been singled out as causes of prior outbreaks.
Thankfully, the CDC has no plans to make Americans eat tired tacos and bland burritos. That said, researcher Magdalena Kendall stressed that "Awareness that salsa and guacamole can transmit foodborne illness, particularly in restaurants, is key to preventing future outbreaks."
