Research UK -The epidemiology, microbiology and clinical impact of Shiga toxin-producing Escherichia coli in England, 2009–2012

Epidemiology and Infection

Between 1 January 2009 and 31 December 2012 in England, a total of 3717 cases were reported with evidence of Shiga toxin-producing E. coli (STEC) infection, and the crude incidence of STEC infection was 1·80/100 000 person-years. Incidence was highest in children aged 1–4 years (7·63/100 000 person-years). Females had a higher incidence of STEC than males [rate ratio (RR) 1·24, P < 0·001], and white ethnic groups had a higher incidence than non-white ethnic groups (RR 1·43, P < 0·001). Progression to haemolytic uraemic syndrome (HUS) was more frequent in females and children. Non-O157 STEC strains were associated with higher hospitalization and HUS rates than O157 STEC strains. In STEC O157 cases, phage type (PT) 21/28, predominantly indigenously acquired, was also associated with more severe disease than other PTs, as were strains encoding stx2 genes. Incidence of STEC was over four times higher in people residing in rural areas than urban areas (RR 4·39, P < 0·001). Exposure to livestock and/or their faeces was reported twice as often in cases living in rural areas than urban areas (P < 0·001). Environmental/animal contact remains an important risk factor for STEC transmission and is a significant driver in the burden of sporadic STEC infection. The most commonly detected STEC serogroup in England was O157. However, a bias in testing methods results in an unquantifiable under-ascertainment of non-O157 STEC infections. Implementation of PCR-based diagnostic methods designed to detect all STEC, to address this diagnostic deficit, is therefore important.

Australia -South Australians warned of salmonella risk linked to meats cooked on spits

ABC News

South Australians are being warned to take care when using home rotisseries or spits after they were linked to more than 20 people falling ill last financial year.

Health Minister Jack Snelling said SA Health investigations identified home cooked pig and lamb on the spit as the main causes of salmonella outbreaks at two separate home gatherings in 2014-15.

“The use of home rotisseries and spits is becoming increasingly common across the state as a fun way to feed large groups, especially with the weather warming up and people wanting to cook outside,” Mr Snelling said.

USA -CDC – Multistate Outbreak of Listeriosis Linked to Soft Cheeses Distributed by Karoun Dairies, Inc. (Final Update)

CDC Eurofins Food Testing UK

Highlights

  • This outbreak investigation is over. However, people could continue to get sick because recalled cheeses may still be in homes, restaurants, or retail locations. Consumers, restaurants, and retailers unaware of the recall could eat, serve, or sell them. Read the Advice to Consumers, Restaurants, and Retailers(http://www.cdc.gov/listeria/outbreaks/soft-cheeses-09-15/advice-consumers.html).
  • CDC collaborated with public health officials in several states and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Listeria monocytogenes infections (listeriosis). Listeria infection can cause a serious, life-threatening illness.
    • Five rare DNA fingerprints of Listeria were included in this investigation.
    • Whole genome sequencing showed that the Listeria strains with the five rare DNA fingerprints were closely related genetically.
  • Thirty people infected with one of the closely related Listeria strainswere reported from 10 states since June 16, 2010.
    • Twenty-eight people were hospitalized. Six illnesses were pregnancy-related; one resulted in a fetal loss. Three deaths were reported from California (2) and Ohio (1).
  • Epidemiologic and laboratory information indicates that soft cheeses distributed by Karoun Dairies were the likely source of this outbreak.
    • Twenty-one (75%) of 28 ill people with available information reported eating soft cheese in the month before becoming ill.
    • Three of seven ill people who specified a brand of cheese reported brands distributed by Karoun Dairies. No other brand of soft cheese was reported more than once.
    • FDA isolated Listeria monocytogenes from two environmental samples collected in September 2015 from the Central Valley Cheese, Inc. manufacturing facility in Turlock, California. Central Valley Cheese, Inc. manufactures cheese for Karoun Dairies. Whole genome sequencing showed that the two isolates were closely related genetically to isolates from ill people.
    • Whole genome sequencing showed that five Listeria isolates collected in 2010 from the same facility were also closely related genetically to isolates from ill people.
  • On September 16, 2015, Karoun Dairies, Inc. voluntarily recalled[PDF – 2 pages] 15 types of soft cheeses that the company distributes due to possible contamination with Listeria.
  • Consumers should not eat, restaurants should not serve, and retailers should not sell recalled cheeses. These products may be contaminated with Listeria and may make people sick.
