Correction to: Prevalence and Antimicrobial Susceptibility of Salmonella Serovars Isolated from U.S. Retail Ground Pork by P.R. Broadway et al. Foodborne Pathogens and Disease 2021;18(3)219–227. DOI: 10.1089/fpd.2020.2853

In the March 2021 issue of Foodborne Pathogens and Disease (vol.18, no.3;219–227) the article entitled Prevalence and Antimicrobial Susceptibility of Salmonella Serovars Isolated from U.S. Retail Ground Pork by P.R. Broadway et al. requires correction.

On page 220 in the Sample collection section under Materials and Methods, additional information has been added.

The first two sentences of the first paragraph of the section previously read:

“A convenience sample of packages of ground pork (n = 865) was obtained from retailers across the United States over a 12-month period. Pork samples were obtained from ≥ 12 cities within each of the 4 geographical regions within the United States (West, South, Central/Midwest, and East) evenly dispersed across three seasons (fall: September–November, winter/spring: January–March, summer: June–August; Table 1).”

The first three sentences of the paragraph now read:

“A convenience sample of packages of ground pork (n = 865) was obtained from retailers across the United States over a 12-month period. The ground pork samples used in this study were collected in 2012 and 2013. Pork samples were obtained from ≥ 12 cities within each of the 4 geographical regions within the United States (West, South, Central/Midwest, and East) evenly dispersed across three seasons (fall: September–November, winter/spring: January–March, summer: June– August; Table 1).”

Also, on page 221, in the Antimicrobial resistance profiling section, a sentence has been added to the first paragraph:

“The resistance breakpoints discussed in the paper are representative of those at the time of sample analysis. Antimicrobial breakpoints as of March 2021 can be found at CLSI (CLSI, 2020). Antimicrobial resistance profiling Antimicrobial resistance of individual isolates was evaluated by determining their minimum inhibitory concentration (MIC) to a standard panel of 15 antibiotics (amoxicillin/clavulanic acid, ampicillin, azithromycin, cefoxitin, ceftiofur, ceftriaxone, chloramphenicol, ciprofloxacin, gentamicin, nalidixic acid, streptomycin, sulfisoxazole, tetracycline, and trimethoprim/sulfamethoxazole) using microbroth dilution.”

On page 224, the footnotes in Table 3 have been amended.

The footnotes previously read:

“*Black line on the left denote the line in which everything to the left of the line is considered susceptible to the antibiotic at that concentration.

*Black lines on the right denote the line in which everything to the right of the line is considered susceptible to the antibiotic at that concentration.

*Spaces between the lines indicate intermediate resistance to the antibiotic at that concentration.”

The footnotes now read:

“*Black line on the left denote the line in which everything to the left of the line is considered susceptible to the antibiotic at that concentration.

*Black lines on the right denote the line in which everything to the right of the line is considered resistant to the antibiotic at that concentration.

*Spaces between the lines indicate intermediate resistance to the antibiotic at that concentration.

The correct number of isolates in Table 3 are: Ciprofloxacin (54@0.015), Tetracycline (23@2), and Trimethoprim/Sulfamethoxazole (2@0.5). With the current breakpoints applied, the number of amoxicillin/clavulanic-resistant isolates is 9/60 (15%), not 1/60 (1.7%) as shown in Table 3 .”

On page 225, two footnotes have been added to Table 4.

“Table 4 frequency calculations included intermediate isolates.”

“Following PFGE and storage, one isolate could not be recovered.”

On page 225, in the Antimicrobial resistance section of the Results and Discussion, a sentence has been added to the first paragraph:

“These samples represent Salmonella isolates from ground pork 2012–2013. Recommendations for antibiotic treatment may have been updated since isolate characterization. Conclusions regarding the absence of Salmonella isolates with antimicrobial resistance of importance to human medicine should be interpreted based on current standards. Most notably, the recommendation for the use of azithromycin in the treatment of salmonellosis (CDC, 2019a). Antimicrobial resistance was determined by MIC analysis utilizing a NARMS surveillance panel of antibiotics (Table 3).”

Also in the same paragraph, the last sentence previously read:

“The CDC reports that severe Salmonella infections in humans may be treated with fluoroquinolones, extended-spectrum cephalosporins, and ampicillin (for susceptible infections), of which none of the Salmonella isolates from this study were resistant (Hohmann, 2001; CDC, 2019).”

This sentence has been modified to read:

“The CDC reports that severe Salmonella infections in humans may be treated with fluoroquinolones, extended-spectrum cephalosporins, and ampicillin (for susceptible infections), and none of the Salmonella isolates from this study were resistant to either fluoroquinolones or extended-spectrum cephalosporins (Hohmann, 2001; CDC, 2019b).”

On page 226, the References section has been updated. A new reference has been added:

“CDC. Centers for Disease Control and Prevention. Antibiotic Resistance Threats in the United States, 2019. Atlanta, GA: U.S. Department of Health and Human Services, CDC, 2019a.”

The existing CDC reference previously listed has been modified to adjust the date for clarity. The reference previously read:

“CDC. 2019. Centers for Disease Control and Prevention, National Center for Emerging and Zoonotic Infectious Diseases (NCEZID), Division of Foodborne, Waterborne, and Environmental Diseases (DFWED). Available at: https://www.cdc.gov/salmonella/general/technical.html accessed May 28, 2020.”

The reference has been corrected to read:

“CDC. 2019b . Centers for Disease Control and Prevention, National Center for Emerging and Zoonotic Infectious Diseases (NCEZID), Division of Foodborne, Waterborne, and Environmental Diseases (DFWED). Available at: https://www.cdc.gov/salmonella/general/technical.html accessed May 28, 2020.”

The online version of this article has been updated to reflect the corrections.

The authors apologize for this oversight.
