BACKGROUND: Animals are the main reservoir of human non-typhoid Salmonella infections and, therefore, antimicrobial susceptibility of food isolates must be monitored. METHODS: 1272Salmonella strains were isolated between 1998 and 2000 from samples of slaughtered pigs, broilers and layers. All isolates were serotyped, phage typed, and their activity to 10 antimicrobial agents was determined by the agar dilution method according to NCCLS standards. RESULTS: The distrubution of the serotypes considerably varied in subsequent years. In 1998 the most common serotypes were S. Enteritidis (28.7%), S. Typhimurium (14.4%), and S. Hadar (8.4%); in 1999, S. Enteritidis (35.0%), S. Typhimurium (8.5%), and S. Brandenburg (7.1%); and in 2000, S. Derby (19.6%), S. Typhimurium (18.7%), and S. Enteritidis (17.5%). The percentages of resistance for 5 antibiotics are given in the table. [table: see text] All isolates were susceptible to ceftriaxone and ciprofloxacin. The highest resistance rates were observed among S. Hadar and S. Typhimurium DT104. CONCLUSION: We found alarming resistance rates, particularly among Salmonella from broilers. Differences observed in the percentages of resistance over the 3 year period were related to changes in the distribution of serotypes.
