In today\u2019s world of supermarkets filled year-round with a diverse array of fruits and vegetables, it is easy to forget where our fresh produce comes from. The two United States <\/span>E. coli <\/span><\/i>outbreaks of 2018 were a startling reminder. In the spring and fall of last year, stores and restaurants pulled romaine lettuce from their shelves and menus because it was potentially carrying the dangerous <\/span>E. coli <\/span><\/i>bacteria. According to the U.S. Centers for Disease Control and Prevention (CDC), the June outbreak infected a reported 210 people. Of these, 96 were hospitalized, 27 developed kidney failure, and five died of their illness.1<\/span> The latest outbreak infected 62 people from October 7 to December 4, with 25 hospitalizations and no deaths.2<\/span><\/span><\/p>\n

How did not just one, but <\/span>two<\/span><\/i> romaine lettuce outbreaks happen last year? Investigations are ongoing, but the number one suspect is waste-filled water.<\/span><\/p>\n

Finding the Source<\/b><\/h2>\n

The CDC and the U.S. Food and Drug Administration (FDA) used whole genome sequencing to trace the outbreaks back to their origins. Whole genome sequencing allows scientists to read the unique DNA of germs, a process not unlike reading fingerprints at the scene of a crime. The more similar germs\u2019 DNA is to each other, the more likely it is that they came from the same source.3<\/span><\/span><\/p>\n

These tests indicated that June\u2019s <\/span>E. coli <\/span><\/i>outbreak came from canal water in the Yucca, Arizona, growing region. The second outbreak was traced back to an agricultural water reservoir in California\u2019s central coastal region.<\/span>3<\/span> This water could have contaminated the lettuce when farmers used it to irrigate their crops and dilute pesticides. <\/span><\/p>\n

But how did <\/span>E. coli <\/span><\/i>get into the water in the first place? Investigators have found a likely answer: the canal in Yucca is located near a concentrated animal feeding operation. Concentrated animal feeding operations keep large amounts of livestock (for example, 1,000 or more beef cattle) in a comparatively small area of land.4<\/span> Such places produce huge amounts of waste, and it is very possible that some found its way into the canal. Animal waste happens to be a major source of <\/span>E. coli<\/span><\/i>.5<\/span><\/span><\/p>\n

As for the water in California\u2019s coastal region, the ultimate source of the <\/span>E. coli <\/span><\/i>is still under heavy investigation. <\/span><\/p>\n

What Can You Do?<\/b><\/h2>\n

The FDA has recently made an agreement with grower-shippers to label their romaine lettuce with the region where they were grown and the harvest date. This makes it easier to identify and remove contaminated produce.6<\/span> In terms of prevention, we hope that the results from the current investigations will prompt effective action to prevent potential sources of disease from tainting agricultural water supplies. <\/span><\/span><\/p>\n

In the meantime, we recommend the following actions to minimize the risk of contracting <\/span>E. coli <\/span><\/i>from food:<\/span><\/p>\n

    \n
  1. Purchase lettuce that is labeled with a growing region and harvest date. Therefore, in the case of a future outbreak, you will be able to quickly determine if you are at risk.<\/span>7<\/span><\/li>\n
  2. Avoid foods that have an exceptionally high chance of carrying <\/span>E. coli<\/span><\/i>. This includes undercooked ground beef, unpasteurized milk and juice, cheese made from unpasteurized milk, and (sadly) raw cookie dough.8<\/span>
    \n<\/span><\/li>\n
  3. Wash your hands before preparing food.<\/span><\/li>\n
  4. Wash your hands after diapering infants or interacting with livestock animals and\/or their environment and supplies.8<\/span>
    \n<\/span><\/li>\n
  5. Prepare raw meat separately from fruits and vegetables.2<\/span>
    \n<\/span><\/li>\n
  6. Do not drink untreated water or swim in contaminated areas.8<\/span> <\/span><\/li>\n<\/ol>\n
