Article Synopsis
  • Salmonella enterica is a major cause of foodborne illness, with serovar Kentucky becoming increasingly common in broiler chickens due to the acquisition of a ColV virulence plasmid.
  • A study of 902 Salmonella isolates showed that the ColV plasmid was predominantly found in S. Kentucky (72.9%), enhancing its colonization ability in chickens and increasing the risk of disease.
  • Analysis of ColV plasmids from different S. Kentucky isolates revealed a similar genetic structure, indicating a potential for horizontal gene transfer of virulence, raising concerns for human health.

Campylobacter jejuni isolates (n = 340) were collected from nine turkey flocks in three rotations (A, B, and C) at a newly established turkey production facility in North Dakota and at processing. Samples were collected at weeks 1, 4, 9, and 18, as well as at two stages on the processing line at the processing plant. Campylobacter was not isolated from the first flocks in the rotations (A1, B1, and C1), but was detected at week 18 in the second flock groupings and at week 9 in the third flock groupings.
