business news in context, analysis with attitude

USA Todayreports that the US Food and Drug Administration (FDA) has concluded that “a number of California farms may have produced romaine lettuce contaminated with E. coli, causing an outbreak in late 2018 that hospitalized dozens of Americans.”

Only one of those farms was specifically identified - Adam Brothers Farming of Santa Barbara County.

However, the FDA conclusions came up short in figuring how why the outbreak took place.

“The lone positive E. coli test was found in sediment in a water reservoir on an Adam Brothers farm in Santa Maria,” USA Today writes. “The agency stated it did not know how the reservoir became contaminated but provided possibilities, including that the water was ‘most likely’ not properly treated with sanitizer and extensive wild animal activity nearby, such as animal grazing. It’s also possible that E. coli was in the reservoir for months or years before the outbreak.

“The other farms implicated in the outbreak did not use the reservoir. The FDA stated investigators could not find a potential source of contamination at those farms.”

The FDA has recommended that “farmers review federal produce safety rules and said the agency will work with the produce industry to create quick and accurate ways to trace outbreaks back to their source.”

Yikes. Not sure about you, but there is way too much ambiguity in this final report for my taste.
