Denmark -E. coli sickens 26 in Denmark; no cases in other countries as yet – STEC E.coli O126

Posted on November 8, 2018 | Leave a comment

Food Safety News Ecoli Istock

Danish officials are investigating an E. coli outbreak that has 26 cases with three out of four being children.

Statens Serum Institut (SSI), the agency responsible for the preparedness against infectious diseases in Denmark, said the source of infection is not yet known but an investigation is under way.

SSI told Food Safety News that the 26 confirmed patients’ ages are between less than 1 year old to 95 years old, with 19 being children younger than five years of age. One person has been hospitalized. No deaths have been reported.

Cases with a specific type of Shiga toxin-producing E. coli (STEC) or Verotoxigenic E. coli (VTEC) have been reported to SSI in the past few weeks.

E. coli O26:H11 illnesses are spread across the country, but are primarily in the cities of Copenhagen, Aarhus and Odense. Illness onset dates range from Aug. 23 to Oct. 10.

Food Poisoning Bulletin

Public health officials in Utah are investigating an increase in Shiga toxin-producing E. coli infections (STEC) in that state, according to the Utah Department of Health. The source of this Utah STEC outbreak has not been identified, but some patients said they visited farms, corn mazes, and petting zoos before they got sick.

Research – Prevalence of Salmonella, Campylobacter, and Shiga Toxin–Producing Escherichia coli on the Surfaces of Raw Poultry Packages

Contamination on the exterior surfaces of raw poultry packages can be transmitted to hands and food contact surfaces during shopping and handling. This study compared the level of microbial contamination and prevalence of foodborne pathogens on the surfaces of raw poultry packages as related to the types of products, types of packaging, and packaging conditions. Packages of whole chicken, cut-up chicken (breast and leg quarter), and ground turkey were purchased from retail stores. Aerobic plate counts (APCs) were significantly different (P < 0.05) among types of products and packaging materials, with ground turkey packages and the heat-sealed, high-walled containers being the lowest. APCs were significantly lower (P < 0.05) when the packages were intact and tight compared with intact and loose. Of the 105 packages, there were 10 (9.5%) with the presence of either Shiga toxin–producing Escherichia coli (STEC) or Campylobacter; of those packages, 6 (5.7%) were positive for STEC, 7 (6.7%) were positive for Campylobacter, and 3 (2.9%) were positive for both pathogens on the surfaces. Salmonella was not detected on the surfaces of all tested packages. Surfaces of whole chicken packages were significantly (P < 0.001) more likely to have detectable levels of Campylobacter and STEC than those of cut-up chicken packages. Packages that were positive for Campylobacter and/or STEC had significantly (P < 0.005) higher APCs than negative packages. The results suggested that STEC is another significant pathogen present on the surfaces of poultry packages in addition to Campylobacter. The presence of STEC on the external packaging of raw poultry raises a concern because consumers may not expect such pathogens on the surfaces of poultry packages.
