VTEC O157 outbreak associated with watercress

This episode further confirms the importance of vegetables as vehicles of VTEC infection. Moreover, the role of domestic and wild animals in the contamination of the crop underlines the importance of applying Good Agriculture Practices (GAP) and Good Hygiene Practices (GHP), in particular biosecurity, to the production processes of vegetables intended to be consumed raw. This applies to the open field production of either vegetables or seeds to be used for sprouting, as stated in the new EU regulations on the safety of sprouts, and also involves the microbiologic quality of the water used in the production process, usually deriving from water streams close to the field.

VTEC contamination of raw flour used by food industry

The ProMED announcement of 15 Nov 2013 is about an outbreak of infections with VTEC O121 occurred in the United States and linked to a brand of frozen food products.
According to CDC and FDA (, a total of 35 cases were reported from 19 states, 31 % were hospitalized and 2 developed HUS. The outbreak was recognized by comparing the PFGE "fingerprints" of the strains produced by PulseNet, the national subtyping network. Interviews of the patients and traceback investigations indicated the consumption of frozen food products of a given brand as the source of the outbreak. The outbreak O121 strain was identified in two different frozen products (mini chicken quesadillas, mini pizza slices) of the brand...

VTEC O157 infection acquired by swimming in lakes

The following ProMED announcements is about 2 VTEC outbreaks linked with swimming in lakes and occurred between June and July in the US.
In one of the episodes the serotype of the EHEC strain is not reported, but it is likely that it was O157 as well.
These episodes underline the importance of waterborne outbreaks associated with recreational water. Contamination my occur from human wastes, but free ranging ruminants might contaminate even lakes that appear to be "incontaminated" natural environments.
