Interviews with ill people indicate pig ear dog treats are the likely source of this outbreak. A common supplier of pig ear treats in this outbreak has not been identified.

The outbreak strain is multi-drug resistant, according to officials. Whole genome sequencing analysis of Salmonella isolates from 30 ill people predicted antibiotic resistance or decreased susceptibility to ampicillin, ciprofloxacin, gentamicin, nalidixic acid, streptomycin, sulfisoxazole, tetracycline, and trimethoprim-sulfamethoxazole.

These antibiotic-resistant infections may be difficult to treat with commonly recommended antibiotics, and may require a different antibiotic choice.
