| Quarterly Progress Report on Salmonella Testing of Selected
Raw Meat and Poultry Products: Preliminary Results, April–June 2010 |
Attachments to this report:
This report discusses the Salmonella verification sampling results for the second quarter CY 2010 as presented in Tables 1-10,
Chart 1, and Figures 1-8. This data is presented in the format discussed in the Salmonella second quarterly report
CY 2008 which can be accessed on the FSIS website at
http://www.fsis.usda.gov/science/
Q2_2008_Salmonella_Testing/index.asp.
Table 1
Table 1 describes the performance standards/guidance for 8 product classes and allowed positives for category 1, 2T, 2 and 3.
Table 2
This table summarizes Salmonella verification samples including Salmonella positive results, based on sample
collection date, from April–June 2010 for all eight product classes.
Tables 3-10
Tables 3-10 report the proportion of establishments by categories that have completed at least two recent Salmonella
verification-sampling sets. New establishments are not identified in any category until FSIS has documented the results from two sets.
This aligns the quarterly reports with the monthly posting of names of those establishments in Category 2 and 3. An establishment
with its last set ≤ 50% of the performance standard or guidance and the prior set at > 50% of the performance standard
or guidance is sub-categorized as 2T, with T standing for transitioning to Category 1.
Table 7 (ground beef) continues to report only
those establishments eligible for traditional Salmonella verification sampling sets and that have completed two sets.
A total of 678 samples in the low volume ground beef sampling program were collected and analyzed from April–June 2010, and
4 samples were positive for Salmonella.
Chart 1
This chart (PDF) represents the total percentage of establishments within product classes classified by category and sub-category. This chart
indicates that as of June 30, 2010, 83% of establishments are in Category 1, 8% are in Category 2T, 7% are in Category 2, and 2% are in
Category 3.
Figures 1-8
Figures 1-8 summarize Salmonella positive results by product classes for the most recent five quarters. NOTE:
While earlier quarterly reports included individual sample results from "A" sets only, the current report format summarizes data from all
sets. This change was discussed in the 2006-second quarterly report, which can be accessed on the FSIS website:
http://www.fsis.usda.gov/science/
Q2_2006_Salmonella_Testing/index.asp.
Additional information regarding this report
In order to handle sample scheduling more efficiently and to update information on actively producing establishments, the Agency continues
to automate the sampling algorithm process. Therefore, the total number of active operating establishments can change quarter to quarter
as establishments exit or enter the industry. This change does not apply to intermittently producing establishments. The Agency will
continue to categorize them because they are considered to be operating at some level.
Given the revised sampling strategy, the percentage of positive samples is no longer useful as an indicator of trends. As described above,
FSIS has implemented placing establishments into Category 1, 2T, 2, or 3 as an alternative trend indicator for the Salmonella
verification sampling program. While the Agency does not expect the category trend indicator to vary greatly on a quarterly basis,
it should facilitate tracking of overall industry performance when examined over multiple years. Other trend indicators continue to
be considered.
Beginning March 28, 2008, FSIS posted completed Salmonella sample set results from young chicken slaughter establishments with
variable (Category 2) and highly variable (Category 3) process control. In April, there were 14 establishments in Category 2 and 3 in
Category 3. In May, there were 14 establishments in Category 2 and 3 in Category 3. In June, 10 establishments were posted in Category
2 and 3 in Category 3.) FSIS continues to update this information on or about the 15th of each month. The current posting can be accessed at:

As announced in the January 2008 Federal Register Notice: Salmonella Verification Sampling Program: Response to Comments and
New Agency Policies http://www.fsis.usda.gov/OPPDE/rdad/FRPubs/2006-0034.pdf, turkey
establishments in Category 2 and 3 were eligible for posting to the FSIS website beginning May 15 2008. The young turkey product class,
however, has not had Salmonella verification sample set results posted as it has historically met the key criterion for
exclusion from posting by maintaining >90% of establishments in Category 1. For the most recent two quarters, however, the percentage
of young turkey establishments in Category 1 has dropped below 90%. The Agency will post Category 2 and 3 Turkey plants beginning October 2010.
The Agency is still considering publishing category results for establishments in additional product classes. Annual reports summarizing
results for calendar years are available on the FSIS Web site as well as previous quarterly reports. The restructuring of Salmonella
set scheduling, however, means that it is inappropriate to compare results from 2006 onwards to previous years. Similarly, the changes to the
Salmonella verification-sampling program prevent valid comparisons of testing results over time (e.g., quarter-to-quarter or
year-to-year trends).
