FIGURE 7.

Resistance to quinolones, extended-spectrum cephalosporins, macrolides, and colistin in broiler strains of Salmonella from select European Union countries, Iceland, and the United States. Breakpoints used for interpreting MICs were derived from the EUCAST. Among critically important drugs (defined here as macrolides, fluoroquinolones, extended-spectrum cephalosporins, and carbapenems), azithromycin, meropenem, and colistin resistances were very rare and not reported in most countries. *Percentage based on reporting of either cefotaxime or ceftazidime resistance from the European Union or ceftriaxone from United States.
