P.2 left column 3rd paragraph: "Healthy colonized cattle and other ruminants are the most significant animal reservoir harboring E. coli O157:H7 (Ferens and Hovde 2011, Munns et al.2015), and studies have linked ∼75% of the human E. coli O157:H7 outbreaks to food products of bovine origin (primary source). Other reservoirs that may impact transmission include sheep (La Ragione et al.2012, Soderlund et al.2012, Gencay 2014) goats (Pao et al.2005, La Ragione et al.2009 Mersha et al.2010, Alvarez-Suarez et al.2016 Swift et al.2017), flies (Alam and Zurek 2004, Pava-Ripoll et al.2015, Burrus et al.2016), deer (Renter et al.2001) and avian species (Wetzel and LeJeune 2006, Callaway, Edrington and Nisbet 2014a)." |
