LOS ANGELES (AP) — Outbreaks of E. coli illness that sickened 188 people who ate romaine lettuce grown in California probably came from cattle grazing near the farms, the U.S. Food and Drug Administration said in a report released Thursday.
Feces from the cows, which contain the bacteria, is considered “the most likely contributing factor” to three outbreaks of food-borne illness traced to fields in the Salinas Valley, the report said.
The outbreaks occurred last November and December and affected people in at least 16 states and Canada. No deaths were reported.
Investigators concluded that the illness was centered on ranches and fields owned by the same grower and that were located downslope from public land where cattle grazed.
E. coli infection usually causes sickness two to eight days later, according to health authorities. Most people get diarrhea and abdominal cramps. However, some cases can be life-threatening, causing kidney failure and seizures.
E. coli bacteria can get into water and soil through multiple routes, including waste from domesticated animals or wild animals, fertilizer and other agricultural products.
The FDA couldn’t definitely identify a route of contamination for the three 2019 outbreaks. But the agency said the possibilities included water runoff from the grazing area, wind-blown material, or animals or vehicles tracking it to the fields.
“Agricultural water sources used to grow the romaine” also were possible routes, the report’s executive summary said.
Another E. coli outbreak in spring 2018 that sickened more than 200 people and killed five was traced to tainted irrigation water near a cattle lot.
Between 2009 and 2018, federal authorities identified 40 food-borne outbreaks of E. coli in the U.S. “with a confirmed or suspected link to leafy greens,” the FDA said.
Industry groups tightened safety measures following the 2018 outbreak, including expanding buffer zones between growing fields and livestock. The FDA this March issued a plan with a number of voluntary recommendations for reducing the risk of contaminating fields. They include increasing buffer zones between grazing lands and growing fields and adding barriers such as ditches and berms.
The investigation was performed by FDA with the U.S. Centers for Disease Control and Prevention, agencies in several states and Canadian health and food inspection agencies.
8 Stocks Beaten Down by the Coronavirus That Are Too Good to Pass Up
The coronavirus crash has not discriminated in its victims. Large-cap, mid-cap, and small-cap stocks have all been dropping. No sector has been spared either. And while the market flipped from a bear market to a bull market in just three days, there’s still plenty of volatility to cause cautious investors to keep a healthy social distance from many stocks.
The pandemic that is forcing most of us to stay in our homes as much as possible (and if you’re not, please do) is unique for most of us. Demand hasn’t organically diminished. It’s been artificially suppressed. And that means that while it’s fair to say our economy will certainly experience a new normal, there will be a recovery.
And when it comes, many of the companies that were strong before the pandemic broke will continue to show their strength. Investors who are investing in these companies today will be the ones that experience the greatest gains when the recovery happens.
