Serotypes Profile of Salmonella Isolates from Meat and Poultry Products

January 1998 through December 2014

Summary

The Food Safety and Inspection Service (FSIS) conducts nontyphoidal1 Salmonella serotype testing 

on isolates recovered from raw meat and poultry products subject to sampling under the Pathogen 

Reduction Hazard Analysis and Critical Control Point (PR/HACCP) verification testing program. The

results presented here provide an estimate of relative serotype distributions for each product class 

during the 16-year period following implementation of the PR/HACCP program (1998-2014). All 

data sets are reported by calendar year (CY).

Introduction

Salmonella is the leading cause of bacterial foodborne illness in the United States and causes an

estimated 1.2 million illnesses, 19,000 hospitalizations and 380 deaths, each year (4). Attribution 

data from 2014, estimates that 360,000 (30%) of foodborne illnesses are attributed to FSISregulated products which is a 9.3% decrease when compared to 2010 (16,22). The Centers for

Disease Control and Prevention (CDC) reports that the severity of disease depends on a variety of 

factors including host-specific and pathogen-specific factors including the serotype designation (6).

Although there are more than 2,500 Salmonella serotypes, it is estimated that less than 100 of them 

cause human illness (6).

FSIS is committed to implementing, revising and enforcing programs that align with FSIS’ strategic 

goals and Healthy People 2020 Goals to reduce Salmonella illnesses attributable to FSIS-regulated 

products (16,17,18). To this end, FSIS reviews serotype data generated through PR/HACCP sampling

to monitor trends of isolates identified in various products to proactively guide decisions affecting 

food safety and public health.

PR/HACCP program

In the early- to mid-1990s, FSIS conducted nationwide microbiological baseline studies to estimate

the prevalence and levels of bacteria of public health concern in specific food commodities (7,8). In 

July 1996, FSIS published the (PR/HACCP) Systems, Final Rule, based on these baseline studies which 

established pathogen reduction performance standards for Salmonella for establishments that 

slaughter selected classes of food animals or produce raw ground products including carcasses of 

cow/bulls, steers/heifers, market hogs2

, broilers (young chicken), ground beef, ground chicken, and 

ground turkey (7). In June 2006, FSIS implemented Salmonella performance standards for turkey 

carcasses (13). In 2011, FSIS implemented performance standards for Campylobacter and more 

stringent standards for Salmonella in poultry carcasses (chicken/turkey) (14,15). 

 1 Nontyphoidal refers to all serotypes of Salmonella except for Typhi, Paratyphi A, Paratyphi B (tartrate 

negative) and Paratyphi C.

2 FSIS suspended scheduling cows/bulls from sampling in 2011 and market hogs and steer/heifers in 2012 

because of the low number of positive samples.

The Salmonella performance standards provide a measure by which industry and FSIS inspection 

personnel can evaluate whether the food safety system at a particular establishment is effectively

controlling Salmonella. Under a performance standard, each establishment is subjected to a series 

of sampling events. The number of samples and allowable positives in a set of samples (sample set)

vary by product class and pathogen (7,8). The Agency believes that a reduction in human illness 

should result from the implementation and enforcement of performance standards because a 

smaller proportion of raw meat and poultry products will likely be contaminated with Salmonella 

than would be the case without standards (11). 

Serotyping

Serotyping is a process by which the types of Salmonella can be differentiated based on their surface 

antigens (1). The serotypes are based on standard nomenclature according to the Kaufmann-White 

scheme maintained by the World Health Organization (WHO) (21). 

FSIS inspection personnel collect and submit product samples to one of three FSIS Field Service 

Laboratories (FSLs) in Athens, GA; Alameda, CA; or St. Louis, MO for Salmonella analysis. Prior to 

2012, isolates of Salmonella-positive samples were sent to the National Veterinary Services 

Laboratory (NVSL) for serotyping. Since 2012, the Salmonella isolates have been serotyped by the 

Outbreaks Section of the Eastern Laboratory (OSEL) at the FSL in Athens, GA, using a molecular 

serotyping method developed by the CDC (1). Any sample that cannot be serotyped using this 

method is sent to the USDA Animal and Plant Health Inspection Service’s (APHIS) National 

Veterinary Services Laboratories (NVSL) in Ames, Iowa, for traditional serotyping methodology 

(antisera agglutination).

FSIS PR/HACCP Salmonella Data Collection

Prior to 2006, there were two phases of the PR/HACCP for Salmonella in raw products: non-targeted 

and targeted testing. FSIS collected non-targeted or "A" set samples at establishments randomly 

selected from the population of eligible establishments with a goal of scheduling every eligible 

establishment at least once a year. Additional sampling represented sets (referred to as "B", "C", 

and "D") collected from establishments targeted for follow-up testing following a failed set (7,8,9).

From June 2006 until the end of 2014, FSIS has scheduled establishments based on criteria that are 

risk-based rather than random (7,8). The new scheduling criteria focused on establishments with 

the most Salmonella-positive samples, including serotypes most frequently associated with human 

salmonellosis within each product class. (7,8,9,10). As a result of this change in sampling, results 

from establishments prior to June 2006 cannot be compared to those reported following the new 

schedule. 

This report includes aggregate data based on large numbers of test results. Although these data 

provide insight into Salmonella contamination in products sampled under the program, FSIS 

verification sampling is not designed to estimate national prevalence of Salmonella by class of 

products. A true estimate of prevalence can only be derived from randomly selected samples in a 

nationwide baseline study designed specifically to determine prevalence (8).

Future Direction of PR/HACCP Sampling

In January 2015, FSIS announced changes to its current set-based model of sampling to be able to 

estimate the prevalence of Salmonella in FSIS products and monitor trends. The Agency has 

implemented routine sampling and a method called the “moving window” to assess process control 

(15). A moving window is one in which FSIS evaluates a set time period, 52-weeks, in a single 

establishment to assess process control. Routine sampling and the moving window together allows 

FSIS to distinguish between compliant and non-compliant establishments while collecting 

prevalence data. Routine sampling began with young chicken and young turkey carcasses in May, 

2015 (20).

Tables and Figures

Each table presented in this report identifies the ten most common Salmonella serotypes isolated 

annually per specific product class (1998-2014). When more than one serotype ranks in tenth place, 

each serotype in tenth place is listed (Table 1-8). The 10 most common serotypes isolated from a 

specified product class during a given year are identified by name while less commonly identified 

serotypes are included in the "other serotypes" category. When FSIS could not identify a specific 

serotype or identified an isolate as monophasic3 or nonmotile4

, the isolate was entered as 

“Unidentified” in the tables. Isolates that FSIS was unable to serotype are listed in the tables as “Not 

typed." Each table includes the number of isolates of each serotype and category, the percent of 

total serotyped isolates, and the percent of total samples collected.

Highlights of PR/HACCP Salmonella serotype data, CY-2014

In 2014, FSIS sampled across three Salmonella risk-based sampling projects including: young chicken 

(broiler) carcass (HC11_BR), young turkey carcass (HC11_TU), and ground beef (HCO1_GB). Among 

the 18055 samples collected, 472/18055 (2.6%) of the isolates were positively identified and 

serotyped. Among serotyped results, young chicken carcass represented the abundance of positives 

324/472 (68.6%), followed by ground beef 116/472 (24.6%) and turkey carcass 32/472 (6.8%).

The top 10 Salmonella serotypes identified from PR/HACCP testing in 2014 are listed in Table 1a. 

FSIS uses this ranking along with the ranking of product specific serotype results to monitor 

industry’s compliance with regulatory standards, inform future performance standards and compare

with complementary active (i.e.The Foodborne Diseases Active Surveillance Network (FoodNet))

and passive (CDC’s Public Health Laboratory Information System (PHLIS)) Salmonella surveillance 

data that estimate the burden of salmonellosis in the U.S. (3,4,5). Because human salmonellosis 

cases are commonly attributable to non-FSIS regulated foods and non-food sources, FSIS works 

closely with its public health partners to identify the proportion of human salmonellosis attributable 

to FSIS regulated products.

 3 Monophasic means that the Salmonella will produce only one kind of flagellin based on its genetic make-up. 4 Non-motile means that there is no genetic code in the Salmonella for the development of a functional flagellin.

Young Chicken Carcass (Broiler):

In 2014, 8,816 young chicken carcass samples were analyzed under the PR/HACCP program (Table 

1). Salmonella was isolated from 3.7% (325/8816) of these samples. Of the positive broiler samples, 

60.8% (197/325) were positive for S. Kentucky followed by Salmonella Enteritidis 13.6% (44/324) 

(Figure 1). 

Young chicken carcasses are regarded as the product class with the greatest potential to cause 

exposure of the public to Salmonella (18). For this reason, FSIS continues to direct its resources 

toward implementing and revising performance standards to reduce the load of Salmonella in 

chicken carcasses. Since 1998, Salmonella Kentucky has ranked as the most common serotype

identified among PR/HACCP young chicken isolates. Salmonella Kentucky, from chicken carcasses, 

however, is not among the serotypes commonly associated with human illness in the U.S.

Salmonella Enteritidis was the second most common serotype identified in young chicken carcasses 

and is currently the most common serotype associated with human illness (3,12). It also ranks as the 

second most common cultured confirmed isolate from PHLIS (3,5). Eggs are reported to be the most 

common food commodity associated with S. Enteritidis outbreaks (23). There has been a steady 

decline in the PR/HACCP percent positive results for S. Enteritidis in young chicken since 2010

(14.8% to 9.4%).

Ground Beef

In 2014, 7,320 ground beef samples were analyzed under the PR/HACCP program (Table 5). 

Salmonella was isolated from 1.6% (116/7,320) of these samples which is a decrease since 2011 . Of 

the ground beef positive samples, 22.4% (26/116) were positive for Salmonella Montevideo

followed by Salmonella Dublin (12.1%) 14/116 (Figure 2). Since 1998, S. Montevideo has ranked as 

the most common serotype identified among PR/HACCP ground beef isolates. S. Montevideo, from 

ground beef, however, is not among the serotypes commonly associated with human illness in the 

U.S. (3,4,5,24). 

Salmonella Dublin was identified as the second most common serotype among ground beef 

samples, in 2014. S. Dublin is reported to cause more severe illness than any other non-typhoidal 

Salmonella, although it is an uncommon cause of human illness (1,3,4,5).

Salmonella Dublin is a host adapted serotype found in cattle and occasionally in swine, sheep and 

horses that rarely infects humans (1). In a study by Jones et al., comparing the severity of illness

outcomes caused by different serotypes, Salmonella Dublin was found to cause highest rate of 

hospitalization (67%), invasive infection (64%) and deaths (3%) when compared to other serotypes 

analyzed in the study. In cattle herds, S. Dublin can cause high fever, respiratory illness (especially in 

calves) abortions and death (26). Compounding the ability of S. Dublin to cause severe disease in 

both humans and animals is its increasing levels of resistance to ceftriaxone (i.e., 0-92% in humans 

and 0-85% in animals) the primary treatment over the last 15 years (25). Also, salmonellosis caused 

by S. Dublin is frequently multi-drug resistant leading to poorer clinical outcomes (24,25).

Salmonella Dublin was first identified in FSIS PR/HACCP ground beef samples in 2003. Since 2003,

among positive ground beef samples, S. Dublin has ranged between 5%-13%. A few positive isolates 

have also been noted, historically, in steer/heifer and cow/bull carcasses.

Young Turkey Carcass

In 2014, 1,919 young turkey samples were analyzed under the PR/HACCP program (Table 8). 

Salmonella was isolated from 1.7% (32/1919) of these samples which is a decrease from 2013.Of the 

young turkey positive samples, 25.0% (8/32) were positive for S. Reading (Figure 3). Since 2012,

Salmonella Reading has ranked among the top three serotypes identified among PR/HACCP isolates. 

S. Reading has not been considered a major contributor to human salmonellosis from turkey 

products in the U.S. (3,4,5).

a

The ten most commonly isolated serotypes during a listed year are identified by name while less 

commonly identified serotypes are included in the “other serotypes” category. When there is more 

than one serotype in tenth place, all serotypes in tenth place are listed.

b

The “unidentified” designation includes isolates for which a single specific serotype could not be 

determined including rough, and/or nonmotile.

c

Prior to 2004, FSIS classified serotypes identified solely by antigenic formulas as monophasic, such 

as I 4, [5],12:i:-, and included them in the unidentified isolates category.

Of note: The figures display the percent of the isolates identified out of total isolates serotyped for 

each product class. The y axis, the serotype percentage, varies from graph to graph because the 

percent of different serotypes varies by commodity and year.

of Analyzed Samples column due to rounding.

a

The ten most commonly isolated serotypes during a listed year are identified by name while less 

commonly identified serotypes are included in the “other serotypes” category. When there is more 

than one serotype in tenth place, all serotypes in tenth place are listed.

b

The “unidentified” designation includes isolates for which a single specific serotype could not be 

determined including rough, and/or nonmotile.

c

Prior to 2004, FSIS classified serotypes identified solely by antigenic formulas as monophasic, such 

as I 4, [5],12:i:-, and included them in the unidentified isolates category. 

**Sampling sets scheduling suspended for this product class in 2012.

Of note: The figures display the percent of the isolates identified out of total isolates serotyped for 

each product class. The y axis, the serotype percentage, varies from graph to graph because the 

percent of different serotypes varies by commodity and year.

a

The ten most commonly isolated serotypes during a listed year are identified by name while less 

commonly identified serotypes are included in the “other serotypes” category. When there is more 

than one serotype in tenth place, all serotypes in tenth place are listed.

b

The “unidentified” designation includes isolates for which a single specific serotype could not be 

determined including rough, and/or nonmotile.

c

Prior to 2004, FSIS classified serotypes identified solely by antigenic formulas as monophasic, such 

as I 4, [5],12:i:-, and included them in the unidentified isolates category. 

**Sample sets scheduling suspended for this product class in 2011.

Of note: The figures display the percent of the isolates identified out of total isolates serotyped for 

each product class. The y axis, the serotype percentage, varies from graph to graph because the 

percent of different serotypes varies by commodity and year.

*The percentages listed for total positive isolates may not equal the sum of the data in the Percent

a

The ten most commonly isolated serotypes during a listed year are identified by name while less 

commonly identified serotypes are included in the “other serotypes” category. When there is more 

than one serotype in tenth place, all serotypes in tenth place are listed.

b

The “unidentified” designation includes isolates for which a single specific serotype could not be 

determined including rough, and/or nonmotile.

c

Prior to 2004, FSIS classified serotypes identified solely by antigenic formulas as monophasic, such 

as I 4, [5],12:i:-, and included them in the unidentified isolates category.

Of note: The figures display the percent of the isolates identified out of total isolates serotyped for 

each product class. The y axis, the serotype percentage, varies from graph to graph because the 

percent of different serotypes varies by commodity and year.

*The percentages listed for total positive isolates may not equal the sum of the data in the Percent 

of Analyzed Samples column due to rounding.

a

The ten most commonly isolated serotypes during a listed year are identified by name while less 

commonly identified serotypes are included in the “other serotypes” category. When there is more 

than one serotype in tenth place, all serotypes in tenth place are listed.

b

The “unidentified” designation includes isolates for which a single specific serotype could not be 

determined including rough, and/or nonmotile. c

Prior to 2004, FSIS classified serotypes identified solely by antigenic formulas as monophasic, such 

as I 4, [5],12:i:-, and included them in the unidentified isolates category. 

Of note: The figures display the percent of the isolates identified out of total isolates serotyped for 

each product class. The y axis, the serotype percentage, varies from graph to graph because the 

percent of different serotypes varies by commodity and year.
