Technical Abstract: The persistence of Salmonella serotypes on a 31 farm broiler complex was evaluated during multiple growouts over a 10 month time period. A total of 25 different serotypes were isolate, with frequent simultaneous isolations of multiple serotypes from individual farms. When the serotypes recovered from individual farms were further examined, common serotypes were isolated from individual farms only on seven occasions. Furthermore, only on five occasions were multiple serotypes recovered from individual farms on consecutive samplings. A casual association of common serotype isolations among farms with similar flock placement dates was observed in one sampling period. These results indicate little predictability or consistency of Salmonella serotype isolation on individual farms over time.
