Decision Letter - Charles Odilichukwu R. Okpala, Editor

Dear Dr. Gatwiri,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

==============================

ACADEMIC EDITOR:

==============================

Please submit your revised manuscript by Jul 24 2026 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

  • A letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
  • A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
  • An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols. Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io. Read more information on sharing protocols at https://plos.org/protocols?utm_medium=editorial-email&utm_source=authorletters&utm_campaign=protocols.

As the corresponding author, your ORCID iD is verified in the submission system and will appear in the published article. PLOS supports the use of ORCID, and we encourage all coauthors to register for an ORCID iD and use it as well. Please encourage your coauthors to verify their ORCID iD within the submission system before final acceptance, as unverified ORCID iDs will not appear in the published article. Only  the individual author can complete the verification step; PLOS staff cannot  verify ORCID iDs on behalf of authors.

We look forward to receiving your revised manuscript.

Kind regards,

Reviewer #1: This manuscript presents a cross-sectional study assessing food safety knowledge, attitudes, and practices (KAP) among poultry vendors in an urban wet market in Nairobi, Kenya. The topic is relevant and provides useful insights into food safety challenges in informal market settings.

However, several issues need to be addressed to improve the scientific rigor and clarity of the manuscript:

Study design and sampling: The sampling strategy is not clearly described. Clarification is needed on whether the sample was random or convenience-based, as this has implications for selection bias.

Measurement and scoring: The use of an 80% cutoff to classify knowledge, attitudes, and practices is not justified. The authors should provide a rationale or supporting references.

Statistical analysis: Some reported odds ratios have confidence intervals that approach or cross 1, yet are interpreted as significant. The authors should carefully review statistical interpretations and clarify whether multivariable analyses were performed.

Interpretation of findings: Some conclusions are slightly overstated, particularly regarding the relative importance of attitudes versus knowledge. The discussion should better reflect the limitations of a cross-sectional design.

Use of observational data: Although an observational component is mentioned, it is not clearly integrated into the analysis. This should be clarified or strengthened.

Limitations: The discussion of limitations should be expanded, especially regarding potential social desirability bias and generalizability.

Minor comments:

Improve clarity and reduce repetition in some sections.

Ensure consistency in tables and formatting.

Overall, the manuscript addresses an important topic but requires revisions to improve methodological clarity and interpretation of results.

Reviewer #2: The statistical analyses are appropriate, but please see comments in particular about the 'attitude' component of the analysis. It is unclear to this reviewer if that variable is being interpreted correctly.

Reviewer #1: This version of the manuscript is considerably improved compared to the previous submission. The literature review is more thorough, and the discussion is more directly connected to the objectives of the study. Statistics analyses are mostly suitable, but authors are urged to scrutinize logistic regression output.

Certain odds ratios, confidence intervals, and associated p values in Table 3 are contradictory (e.g.

CI including 1, but a significant p-value reported). These numbers must be checked and corrected if applicable. A bit stronger comment in Discussion on the policy and public health implications is warranted. Could add one paragraph highlighting how policy and public health interventions should be adapted to the findings in the context of the informal wet market context.

The discussion on limitations seems adequate, authors may need to briefly reflect that generalizability to other locations is somewhat limited as study was conducted in only one urban wet market.

This paper is overall well-written, methodologically sound and reports an important public health concern. I am happy to accept the paper for publication with the suggested modifications.

Reviewer #2: (No Response)

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
