The safety of consuming romaine lettuce has been a topic of concern for several years, with multiple recalls and outbreaks linked to this popular leafy green. As we delve into 2021, many are left wondering: is it safe to eat romaine lettuce? In this article, we will explore the history of romaine lettuce recalls, the causes behind these outbreaks, and what you can do to minimize your risk of getting sick.
History of Romaine Lettuce Recalls
Romaine lettuce has been implicated in several foodborne illness outbreaks in recent years. One of the most significant outbreaks occurred in 2018, when contaminated romaine lettuce was linked to an E. coli O157:H7 outbreak that affected over 200 people across the United States and Canada. The outbreak was eventually traced back to a farm in Yuma, Arizona, and led to a massive recall of romaine lettuce products.
Another significant outbreak occurred in 2020, when penicillium cirtinum, a type of mold, was found to be contaminated on romaine lettuce grown in Salinas, California. This led to a recall of thousands of pounds of romaine lettuce and a warning from the FDA to consumers to avoid eating romaine lettuce from the Salinas Valley.
Causes of Romaine Lettuce Contamination
So, what causes romaine lettuce to become contaminated? There are several factors that contribute to the risk of contamination:
Romaine lettuce is typically grown in fields where animal waste may be present, which can contain bacteria like E. coli. If the fields are not properly cleaned and sanitized, the risk of contamination increases. Irrigation water is another potential source of contamination. If the water used to irrigate the fields is contaminated with bacteria or other pathogens, it can be absorbed by the plants, making them unsafe to eat.
