Foodborne illness and virulence factors (VF) are public health concerns present at variable abundances in beef microbiome communities. This study assessed abundance of beef pathogens and VF in feces of conventionally- and naturally- raised cattle. Forty-eight pens of cattle, 24 pens per treatment, were included in the study. Composite fecal samples were collected from each pen, DNA was extracted, and shotgun metagenomic DNA libraries were prepared and sequenced. Kraken was used for pathogen identification and the Virulence Factor Database was used to identify VF. No statistical difference (P>0.05) was detected between conventionally- and naturally-raised cattle in pathogen load or VF abundance. Results indicated that cattle diet does not play an important role in food safety risk.
