Is the Prevalence and Shedding Concentrations of E. Coli O157 in Beef Cattle in Scotland Seasonal?

FEMS Microbiol Lett. 2004 Apr 15;233(2):297-300. doi: 10.1016/j.femsle.2004.02.021.

Abstract

The prevalence of Escherichia coli O157 in Scottish beef cattle at abattoir was found to be greater during the cooler months [11.2% (95% CI, 8.4-13.9%)] compared to the warmer months [7.5% (95% CI, 5.4-9.6%)]; the reverse of seasonality of human infections. However, high shedding beef cattle (excreting 10(-4) g(-1)) appear to shed greater concentrations of E. coli O157 in the warmer months which may partly explain increased human infection seasonality at this time.
