E. Coli Epidemic Turns Deadly; Is Your Lettuce Safe?

IN-DEPTH COVERAGE TO PROTECT YOUR HEALTH

One dead in E. coli outbreak | PLUS: How to tell if your lettuce is safe 

BY CORAL BEACH, FOOD SAFETY NEWS | MAY 2, 2018

One person has died in the E. coli outbreak linked to romaine lettuce. There are now 121 confirmed cases across 25 states.

Investigators continue to look for the source of the implicated romaine, as well as how it became contaminated.

In the past week, public health officials confirmed 23 new cases and added three more states to the outbreak map.

A week ago the case count stood at 98 people, making for a 23 percent increase in the number of infected people in seven days, according to the Centers for Disease Control and Prevention.

Of those 102 victims for whom complete information is available, 52 have required hospitalization. California officials have reported one death in their state.

The unusually high hospitalization rate of 51 percent shows the outbreak strain of E. coli O157: H7 is particularly dangerous.

Also, 14 of the sick people have developed hemolytic uremic syndrome, a type of kidney failure that can result in kidney transplants, other life-long health problems and sometimes death.

Additional outbreaks are expected to be reported in the coming weeks, according to the CDC. As of the update Wednesday, the illness onset dates for the outbreak victims range from March 13 to April 21.

“Illnesses that occurred after April 11, 2018, might not yet be reported due to the time it takes between when a person becomes ill with E. coli and when the illness is reported. This takes an average of two to three weeks,” the CDC reported Wednesday.

The people confirmed with infections range in age from 1 to 88, with a median age of 29. Sixty-three percent of ill people are female.

Investigators from the Food and Drug Administration have not yet determined where the vast majority of the suspect romaine was grown. Of the outbreak victims, eight are inmates at a prison in Alaska. Officials there report the inmates ate romaine from whole heads. All other victims in the outbreak reported eating pre-chopped romaine at restaurants and from grocery stores,

The source of the whole head romaine was traced back from the prison to Harrison Farms Inc. in Yuma, AZ. Romaine harvest at the farm concluded March 16, according to the FDA.

Efforts to determine the source of the romaine that was chopped are slow going because of shipping and receiving records through the supply chain that more closely resemble a tangled ball of yarn than they do a paper trail.

The only clue they have revealed to the public so far is that the chopped romaine came from the Yuma area because virtually no other growing region was harvesting significant amounts of the leafy green during the time outbreak victims have become ill.

Consequently, both FDA and CDC have repeated the warnings first issued April 13 to consumers, restaurants and retailers and in effect until further notice. The warnings:

“Do not eat or buy romaine lettuce unless you can confirm it is not from the Yuma, Arizona, growing region. Product labels often do not identify growing regions; so, do not eat or buy romaine lettuce if you do not know where it was grown,” the CDC warns.

“This advice includes whole heads and hearts of romaine, chopped romaine, baby romaine, organic romaine and salads and salad mixes containing romaine lettuce. If you do not know if the lettuce in a salad mix is romaine, do not eat it.”

Restaurant operators and retailers should not serve or sell any romaine lettuce from the Yuma growing region. This includes whole heads and hearts of romaine, chopped romaine, baby romaine, organic romaine and salads and salad mixes containing romaine lettuce, the FDA and CDC advised. Restaurants and retailers should ask their suppliers about the source of their romaine lettuce.

People usually get sick two to eight days after swallowing the E.coli germ, according to the CDC. Most infected people develop diarrhea that can be bloody, severe stomach cramps and vomiting, and most recover within a week. Some infections are very mild, but others are severe or even life-threatening.

Hemolytic uremic syndrome can occur in people of any age but is most common in children younger than 5, adults 65 years and older and people with weakened immune systems. Symptoms of HUS develop about a week after symptoms first appear, when diarrhea is improving. Clues that someone is developing HUS include these decreased frequency of urination, feeling very tired and losing pink color in cheeks and inside the lower eyelids.

People with HUS should be hospitalized. Most recover within a few weeks, but some suffer permanent damage or die.

E. coli infection is usually diagnosed by testing a stool sample. Antibiotics are not recommended until diagnostic testing can be performed and E. coli O157 infection is ruled out. Republished with permission of © Food Safety News.

Is your lettuce is safe? How to avoid contaminated produce 

(Headline Health) Lettuce grows in the dirt, and dirt is … well, dirty. 

E. coli, from the colons of human other other mammals, and rat lungworm, a parasite that is actually even more disgusting than it sounds, have both been found on US-grown lettuce and sickened consumers in recent months.

For both types of contamination, pathogens in the soil ended up in the produce.

Is there a way to avoid soil-borne contamination of fresh produce?

The most effective way to kill microorganisms in produce is to cook it, but that’s not a great option when we’re talking about lettuce – unless you’re making lettuce soup.

The next best option is to peel your produce – great for bananas and avocados, not so much for lettuce.

Your third option is to wash it. Washing produce can be very effective. In the Headline Health kitchen, all produce that’s going to be consumed raw is soaked in a pasta pot filled with cold water and couple tablespoons of white vinegar for five minutes, then rinsed. These steps will greatly reduce pesticide residues and pathogens on most produce.

There’s a special problem, however, with e. coli in romaine lettuce. The bacteria is actually inside the individual leaves, making it impossible to wash off. For this reason, we’ve given up our custom of ordering salad in restaurants, and we ask the lettuce be left off of our burgers and sandwiches.

But there’s one great solution for the lettuce contamination problem – lettuce that never touches soil. 

We’re talking about hydroponic lettuce, grown in a greenhouse in nutrient-enriched water, not in the ground. Learn more in this recent interview with a hydroponic lettuce producer …

Lettuce grower’s healthier option

According to local grower Bill Banta, the recent recall of lettuce produced in Arizona was due to how it was cultivated – not because of negligence.

“It’s happened before and not just in Arizona,” Banta explained. “They’ve had to recall lettuce from California, which is also a big lettuce-growing state.”

Banta and his wife Amanda own and operate Rowland’s Pennsylvania Produce, a hydroponic farm operation which grows seven different types of lettuce in a greenhouse 12 months a year.

“We grow romaine, butterhead, bibb, springmix, kale, arugula, mustard greens and watercress – eight varieties,” Banta explained.

Banta said that several factors could contribute to the Arizona grown lettuce being contaminated with E. coli – including soil born diseases and animal wastes being used as fertilizer.

Another factor is the lettuce is handled many times – including harvesting; shipping it by truck from the farm to a warehouse; shipping it to a distribution center; transporting it to another warehouse; before finally arriving at a local supermarket. Contamination could occur at any point along the route.

The lettuce from Rowland’s Pennsylvania Produce is not subject to E. coli contamination because it uses hydroponics instead of dirt farming to grow its produce.

“Everything is completely environmentally controlled,” Banta explained. “There’s no soil, with 6,000 square feet of growing area.”

“No pesticides are required,” Banta explained. “We are harmonized GAP certified by the USDA. We maintain a very high standard of growing produce. We have food safety plans in place. It’s a very safe and healthy way to grow very little.” Read the full story at wcexaminer.com.
