U.S. health officials are telling people to avoid romaine lettuce grown in Salinas, Calif., Friday, Nov. 22, 2019,  as they investigate a food poisoning outbreak. They also say not to eat the leafy green if the label doesn't say where it was grown.

The Wisconsin Department of Health Services (DHS) reports that state officials have found Escherichia coli O157:H7 (E. coli O157) bacteria in an unopened bag of pre-washed chopped romaine collected from an ill person’s home. Additional laboratory testing is pending to determine if the E. coli O157 found in the pre-washed chopped romaine matches the strain causing the multi-state outbreak linked to romaine lettuce.

The discover was part of the ongoing investigation into the multistate outbreak of E. coli O157:H7 infections, Wisconsin health and food safety officials said.

The E. coli O157 bacteria was found in a bag of chopped Fresh Express® brand Leafy Green Romaine lettuce with a use by date of 11/14/2019 and lot code of Z301 A05B. The source of the romaine identified on the packaging was Salinas Valley, California.

While the bacteria was found in a bag of Fresh Express® brand romaine, it is important to note that not all ill persons in Wisconsin that are included in this outbreak have reported consuming Fresh Express® brand salads, according to the DHS. At this time, no single product, brand, or variety of salad has been reported by all ill individuals. The investigation is ongoing to determine the source of contamination and if additional products are linked to illness.

On Dec. 10, Minnesota state health officials said five Minnesotans have gotten sick from eating salad kits linked to an outbreak of E. coli. 

The Minnesota Department of Health says the Minnesotans became ill between Nov. 8 and Nov. 16. Two people were hospitalized. The ill Minnesotans ranged in age from 21 to 91. Four were from the Minneapolis-St. Paul are and one from Greater Minnesota.

Officials say nine people from three states have gotten sick. The infections are linked to Fresh Express Sunflower Crisp Chopped Salad Kits. 

The Centers for Disease Control and Prevention has issued a safety alert about the salad kits.

E. coli lawsuit filed

PRNewswire reported that OFT Food Safety & Injury Lawyers filed the first lawsuit in the multistate 2019 E. coli O157:H7 outbreak linked to romaine lettuce grown in Salinas, California. The lawsuit was filed in the Circuit Court for Milwaukee County (File No. 2019 CV 009273) on Dec. 5, 2019.

The Plaintiff in the lawsuit contracted an E. coli infection from lettuce purchased at Pick 'n Save in Kenosha, Wisconsin. She ultimately developed hemolytic uremic syndrome (HUS), a potentially fatal complication of E. coli infections that causes kidney failure. The suit names Roundy's Supermarkets Inc., the parent company of Pick 'n Save, as a defendant.

OFT Food Safety Lawyer Brendan Flaherty says that the outbreak shows a deep problem with the industry. "The human cost of E. coli contamination in romaine has been staggering. Where are the field-to-fork changes that will stop this from happening?"

Ryan Osterholm, Food Safety Lawyer at OFT Law, says his client wants answers to help stop future outbreaks. "This is at least the fifth E. coli outbreak in the last several years with leafy greens. Whatever is causing these outbreaks must stop. We fully intend to get to the bottom of exactly how a bag of lettuce almost killed our client."
