Coronavirus: Panic vs. Preparedness, Plus Some Perspective

The storm is coming, so you need to stock up on supplies: candles, batteries, plywood . . . oh, wait; that’s for a hurricane. But our concierge family practice doctors at MD 2.0 in Jupiter want you to think of the coronavirus in much the same way. As with hurricanes, the coronavirus can be deadly. But also like a hurricane, there’s no need for panic. Just some information, some perspective, and some common-sense measures to prepare for the coming outbreak here.

What’s Going On with Romaine Lettuce?

Just in time for your holiday meals, one popular salad staple has landed—again—on the recall list. Our concierge family practice doctors in Jupiter are as curious as you are about the seemingly endless recalls of romaine lettuce, so we wanted to look into why this keeps happening:

  • Newsweek, 11/27/19: “Romaine Lettuce Recall: Six People Suffer Acute Kidney Failure Following E. Coli Outbreak
  • NBC News, 11/20/18: Don’t Eat Romaine Lettuce, CDC Cautions After E. coli Outbreak
  • NBC News, 6/1/18: Romaine Lettuce E. Coli Outbreak Kills 4 More People
  • for a total of five romaine lettuce-related E. coli outbreaks in less than two years.

 

We wondered: Is there something about romaine lettuce, in particular, that attracts the E. coli bacterium? As it turns out, there seem to be two factors implicated in the repeated outbreaks: the locations where it’s grown and the shape of its growth.

Unfortunately, despite the concerted efforts of federal, state, and local scientists, no one seems to have a definitive answer as to why this otherwise healthy and tasty vegetable has been causing so many problems recently. But researchers are getting closer.

 

Most recent outbreak

Symptoms of E. coli bacterial infection include stomach pain or non-bloody diarrhea that worsens over several days. It can take up to 10 days to begin feeling symptoms after consuming affected food, which is why outbreaks are so difficult to track down.

The infection is normally self-limiting, meaning the body fights it off with no complications other than feeling fairly miserable for a few days. But it can also lead to more severe complications, especially for infants and children under five, older adults, and those with compromised immune systems.

In the most recent outbreak last month, 67 incidents of food poisoning linked to romaine lettuce were reported across 19 states. On November 26th, the Centers for Disease Control and Prevention (CDC) warned consumers not to eat any romaine lettuce grown in the Salinas area. This includes any type of romaine lettuce, as well as pre-cut or premixed or packaged salads, spring mixes, and Caesar salad, or any sandwiches or wraps that might contain romaine lettuce.

Whether the label says “grown in Salinas” or doesn’t specify its origin, the CDC recommends discarding it. Romaine lettuce that has been grown in a greenhouse or hydroponically appears to be safe.

 

Possible causes

Nearly all romaine lettuce grown in the U.S. originates from two main areas: the Salinas Valley in California and the Imperial and Coachella valleys in Southern California and around Yuma, Arizona.

The affected lettuce has been found to be contaminated with a strain of E. coli known as O157:H7, which produces a type of toxin that can lead to severe gastrointestinal illness, as well as kidney failure, and possible death.

This particular strain is common in animals, including goats, deer, feral pigs, and especially cattle. Last year’s outbreak was attributed to contamination of surface water possibly used to irrigate and harvest the crop (with high-pressure water knives, which are used to cut the vegetables, as opposed by slicing them from the roots by hand).

Perhaps not surprisingly, many of the outbreaks have occurred within weeks of the time when nearby farming operations fertilize their fields. And the spring 2018 outbreak was tentatively linked to a nearby cattle factory farm, although no conclusive cause was proved. It would certainly make sense, however, if such a concentrated source of bovine fecal matter was so close, that the contamination could have migrated from that source.

The other problem with romaine lettuce is that it’s normally not cooked. Because of the large-scale way we produce our food, much of it is contaminated with such bacteria as E. coli and salmonella, which proper cooking methods destroy. But because romaine’s crinkled leaves grow in an elongated rosette shape, it’s difficult if not impossible to wash it sufficiently to remove all of the surface contamination.

 

What should you do?

The U.S. Food and Drug Administration (FDA) provides the following advice to minimize the chances of contamination.

Always practice safe food handling and preparation measures. Wash hands, utensils, and surfaces with hot, soapy water before and after handling food.

For refrigerators and other food preparation surfaces and food cutting utensils that may have come in contact with contaminated foods, it is very important to thoroughly clean these areas and items.

Consumers should follow these simple steps:

  • Wash the inside walls and shelves of the refrigerator, cutting boards, and countertops; then sanitize them with a solution of one tablespoon of chlorine bleach to one gallon of hot water; dry with a clean cloth or paper towel.
  • Wash hands with warm water and soap for at least 20 seconds before and after handling food.
  • Wipe up spills in the refrigerator immediately and clean the refrigerator regularly.
  • Always wash hands with hot, soapy water following the cleaning and sanitization process.

If you think you have become ill from eating contaminated foods, be sure to talk to us. While food poisoning may result in nothing more than a few days of misery, it can also be dangerous. We can advise you on the best ways to recover.
