An update about porcine brucellosis and pseudorabies sample submissions and accommodations for swine exhibition serology testing:

An Arkansas porcine serology chart is required for porcine brucellosis and pseudorabies sample submissions. A federal brucellosis chart can be used for that disease only. Samples will not be tested until the relevant chart is received. See notes for brucellosis buffered acidified plate antigen (BAPA) test and brucellosis card test. Tests are performed on Mondays only. The updated sample submission cutoff is 8 a.m. on Monday. Samples submitted after the cutoff time will be held until the next scheduled day. 

During the state fair season, a second day of testing will be offered on Thursday with an 8 a.m. cutoff submission time. Samples submitted after the cutoff time will be held until the next scheduled day. Please see the policy above for testing beyond the state fair season. 

ALL results will be released during the next business day following testing. 
ALL positive samples will be sent to the National Veterinary Services Laboratory for confirmation, and turnaround times are subject to their schedule.
