Frequently Asked Questions Acknowledgements

How much will the testing 

cost me?

A producer will incur no 

additional cost to participate 

in influenza surveillance.

Will I know if my samples are 

entered as anonymous or 

traceable?

All sample results will be 

reported anonymously to USD

unless an owner wants the sample 

to be traceable. In that case, written

permission from the owner needs 

to be included.

What happens to the samples 

I submit to the diagnostic lab?

If chosen for influenza surveillance,

samples go through a series of 

standardized tests for SI

Anonymous

Traceable 

Surveillance

Routine samples collected

from clinical respiratory 

cases and submitted to 

participating diagnostic labs 

are eligible for influenza 

surveillance.

Same as anonymous

surveillance.

“Client-requested”

diagnostic lab results 

will be reported back to 

the submitter as usual, 

under current laboratory 

confidentiality protection. 

Influenza surveillance data

will be available in addition 

to “client-requested” 

results.

Diagnostic labs will submit

some but not all of the 

diagnostic lab cases into 

the influenza surveillance 

program.

Same as anonymous

surveillance.

All test results for the 

influenza surveillance 

program will be submitted 

to USDA anonymous

with no owner or submitting 

veterinarian information. 

Aggregate results will only 

be identified to the state 

level.

Test results for the

influenza surveillance 

program will be submitted 

to USDA as traceab

owner and submitting 

veterinarian information 

will be included—only 

when producers provide 

written permission.

Anonymous surveillance 

adds to the confidentiality 

of the diagnostic lab results 

in the surveillance program 

by removing the identity of 

the owner and submitting 

veterinarian.

Traceable surveillance

provides additional 

information that may help 

lead to a more detailed 

analysis of influenza 

change and movement.

Applies information on 

circulating SIV viruses 

to improve herd health.

Improves reliability of 

SIV diagnostic testing.

Provides information to 

help develop effective 

Swine Influenza Virus 

(SIV) vaccines.

Anonymous or traceable 

influenza survillance data 

from diagnostic labs will 

be available for analysis by 

researchers, the pork industry, 

animal health and public 

health officials.

Results from the diagnostic 

workup will be provided 

to you as usual.

Continue to work with your 

herd veterinarian to submit 

samples from pigs with 

respiratory disease.

Results from anonymous data 

can only be identified by state.
