*Salmonella Newport–multidrug-resistant AmpC (MDRAmpC) is resistant to at least chloramphenicol, streptomycin, sulfamethoxazole/sulfisoxazole, tetracycline, amoxicillin-clavulanic acid, ampicillin, cefoxitin, ceftiofur, and cephalothin and shows decreased susceptibility to ceftriaxone. Table includes case-patients with Newport-MDRAmpC and pansusceptible infections only. UD, undefined.
†A specific exposure period was not assessed except for travel. Other exposures reported for case-patients included eating raw ground beef (1 MDRAmpC), eating raw cookie dough (1 MDRAmpC and 1 pansusceptible), preparing a raw chicken pet diet (1 pansusceptible), contact with an ill family member (1 MDRAmpC and 1 pansusceptible), and attending a pig roast (6 MDRAmpC and 1 pansusceptible).
‡At least MDRAmpC resistant.
