USA – FDA Sampling of Romaine Lettuce in Yuma Finds No Widespread STEC or Salmonella Contamination

Food Safety Tech

Following last year’s widespread E.coli O157 outbreak involving romaine lettuce linked to the Yuma, Arizona growing region (Spring 2018), FDA launched a sampling assignment to test romaine lettuce for pathogenic Shiga toxin-producing Escherichia coli (STEC) and Salmonella spp. The microbiological surveillance samplingbegan on December 18, 2018 in the Yuma region and focused on 26 commercial coolers and cold storage facilities to allow FDA to sample multiple farms from several locations at once. The agency collected and tested a total of 188 samples for both pathogens. It did not detect Salmonella in any sample; STEC was detected in one sample, but additional analysis found that the bacteria was not pathogenic.

“The findings of this assignment suggest that there was no widespread Salmonella or STEC contamination of romaine lettuce from the Yuma growing region during the period when sampling occurred. As a next step, the FDA is working with leafy green stakeholders in the Yuma region to consider a longer-term environmental study to identify and control risks that will prevent future outbreaks, with the ultimate goal of protecting consumers. – FDA

The point of the sampling assignment was to determine whether target pathogens were present, and if so, to respond quickly before contaminated products reached consumers.

UK – Listeria outbreak in English hospitals: update

Apologies for this being late but i have been on holiday 🙂


06 August 2019

Article: 53/3104

The Public Health England (PHE) team investigating cases of listeriosis linked to sandwiches and salads in NHS hospitals in England has confirmed that, since the last update on 26 June 2019, there has been another death, bringing to six the total number of deaths linked to this outbreak.

The individual who died was one of the nine previously confirmed cases. The individual is considered to have acquired listeriosis from Good Food Chain products while at Western Sussex Hospitals NHS Foundation Trust.

PHE continues to test all samples of listeria on an ongoing basis to check if they are linked to this outbreak. To date, thirty-four samples have been tested, with none linked to the outbreak.

There have been no new cases of listeriosis linked to this outbreak. Investigations are continuing and the public should be reassured that the risk continues to be low.

No cases have been reported in Scotland so far.
