Methodology

Every fact published on this reference is rated for source confidence and sourced to a primary authority. This page documents the verification discipline applied to all content, the source tier hierarchy used to evaluate evidence, and the explicit list of commonly-circulated claims that have been investigated and disconfirmed.

Source Tier Hierarchy

Tier 1 — Authoritative

Citations directly to federal regulators (CMS, OSHA, EPA, FDA, CDC, USDA, VHA, IHS), accrediting bodies (The Joint Commission, DNV-GL, HFAP, CIHQ), state regulators (state Departments of Health, state Departments of Agriculture, state structural pest control boards, state environmental quality agencies), and the Entomological Society of America Certification Corporation (for matters relating to the Board Certified Entomologist credential). Tier 1 sources are cited directly.

Tier 2 — Recognized Authority

Citations to AHRQ, NIOSH, the National Pest Management Association QualityPro standards, peer-reviewed academic literature in facility management, infection control, and entomology, and published standards from AORN, USP, APIC, ASHE, and the Facility Guidelines Institute (FGI). Tier 2 sources are cited directly.

Tier 3 — Reference Only

Industry publications, vendor whitepapers, and trade press. Tier 3 sources are used only to identify a Tier 1 or Tier 2 source to verify against. If a claim only exists in Tier 3 material, the claim is flagged as unverified and is not published as a stated fact in this reference.

Source Confidence Ratings

HIGH Confidence

The verbatim text or substantive claim has been directly fetched from a primary source in real time and verified by extraction or quotation. Page metadata includes the source URL and the date of most recent verification.

MEDIUM Confidence

The primary source exists but cannot be directly fetched. This typically occurs where the primary source is behind an institutional paywall (Joint Commission CAMH e-edition, USP-NF, AORN eGuidelines+) or where the primary source is rendered in a JavaScript framework that cannot be crawled (the Utah eRules portal at adminrules.utah.gov). Where MEDIUM confidence applies, the page discloses the limitation and identifies the secondary aggregator used. Litigation-grade applications should obtain institutional access to verify the verbatim source.

KILLED — Investigated and Disconfirmed

The claim has been investigated against primary sources and found to be fabricated, mis-cited, or attributable only to Tier 3 sources without Tier 1 or Tier 2 support. KILLED claims are not published as stated facts but are explicitly catalogued so that future researchers do not re-introduce them. The list below catalogues every claim investigated and excluded during the foundation phase of this reference.

Investigated and Excluded Claims

The following claims have been investigated and disconfirmed. Each is paired with the disconfirming finding and primary source. This list is not exhaustive; it documents the claims most commonly circulated in vendor materials, industry publications, and prior research that have been investigated against primary sources.

Federal Regulatory Claims

• "CMS State Operations Manual Appendix A contains pest interpretive guidance." Disconfirmed. A full-document text extraction of Appendix A Rev. 238 (Issued 03-20-2026), 613 pages, 27,201 lines, returns zero matches for pest, vermin, rodent, insect, infestation, roach, cockroach, rat, mice, mouse, or "integrated pest" across the entire document. The 2016 archived version contained a single bullet under A-0749; that bullet does not appear in the current operational manual.
• "42 CFR §488.28 specifies a 10-calendar-day plan-of-correction submission requirement verbatim." Disconfirmed. §488.28 specifies a 60-day compliance expectation. The 10-day PoC submission deadline exists in CMS State Operations Manual Pub. 100-07, Exhibit 152 — sub-regulatory guidance, not codified regulation.
• "21 CFR §123.1 Applicability for Seafood HACCP." Disconfirmed. §123.1 does not exist as an enumerated section. Part 123 Subpart A begins at §123.3 Definitions. Scope is established through §123.3 definitions and §123.6's mandate. Verified via direct eCFR fetch.
• "Federal HACCP regulations apply to hospital food service." Disconfirmed. 21 CFR Parts 120 and 123 (FDA HACCP for juice and seafood), 9 CFR Parts 304, 310, and 417 (USDA-FSIS HACCP for meat and poultry) do not apply to hospital food service. Hospital food service is governed by state-adopted Food Code provisions.
• "7 CFR Part 110 federal recordkeeping requirements for restricted-use pesticides remain in effect." Disconfirmed. USDA rescinded 7 CFR Part 110 effective July 11, 2025 (Federal Register Vol. 90 No. 90, May 12, 2025, FR Doc 2025-08220). State-level recordkeeping rules now govern.

CDC HICPAC Claims

• "CDC HICPAC issued a formal 2019 update to the Environmental Infection Control Guidelines adding water management and construction sections." Disconfirmed. CDC's own update log shows no 2019 substantive update to the 2003 guideline. The 2003 guideline remains the active document. The "July 2019" entry on CDC's updates page is an unrelated Interim Measles Infection Control Recommendations document. Water management for healthcare buildings is governed by separate documents (ASHRAE Standard 188; CMS QSO-17-30).
• "HICPAC Section E.VI contains the pest control recommendations." Disconfirmed. Pest Control recommendations are at Section E.V. (NOT E.VI). Section E.VI contains Special Pathogens recommendations (MRSA/VRE, C. difficile, CJD). Verified via direct CDC MMWR primary source fetch.
• "HICPAC Section E.V. background narrative names specific cockroach, rodent, and ant species and discusses operating rooms, ICUs, and protective environments." Disconfirmed. The species-name narrative and OR/ICU/PE discussion does not appear in Section E.V. of Part II. Part II is the recommendations document; species detail may exist in Part I (a separate document) but was attributed to E.V. without verification.
• "All four HICPAC Section E.V. recommendations are Category II." Disconfirmed. E.V.2 (window screening) is Category IB. E.V.1, E.V.3, and E.V.4 are Category II. Verified verbatim against CDC MMWR Recomm Rep 2003;52(RR-10).

Joint Commission Claims

• "Joint Commission Perspectives July 2019 announced an EC.02.06.01 revision removing Integrated Pest Management language." Could not be verified. No primary or secondary source surfaces a July 2019 Perspectives announcement matching this description. The EC.02.06.01 standard's published text does not contain explicit IPM language before or after 2019.
• "The Joint Commission SAFER Matrix launch was announced in Perspectives Vol. 36 No. 11, November 2016." Disconfirmed. The SAFER Matrix announcement was the May 2016 Perspectives. SAFER became effective for psych-deemed hospitals on June 6, 2016 and for all other accreditation programs on January 1, 2017.
• "Joint Commission Immediate Threat to Life findings must be corrected within 45 calendar days of survey close." Disconfirmed. The actual ITL framework is 72 hours initial identification with up to 23 days maximum for full resolution. The 45-day timeline is the Evidence of Standards Compliance submission deadline for Preliminary Denial of Accreditation situations, not the ITL correction deadline.

Cost and Litigation Claims

• "Average hospital-acquired infection cost is $50,000." Disconfirmed as unsourced. Per-event HAI costs vary across nearly two orders of magnitude per Zimlichman et al. 2013 (JAMA Internal Medicine 173[22]:2039-2046), from $896 (CAUTI) to $58,614 (MRSA central line- associated bloodstream infection).
• "Average hospital pest litigation cost is $75,000 to $250,000." Disconfirmed as unsourced. No primary-source dataset exists on hospital pest litigation costs. Plaintiff firms specializing in pest litigation explicitly state there is no average. The published verdict universe is biased toward plaintiff wins, larger awards, and cases attorneys publish; hospital settlements are disproportionately under non-disclosure agreement.
• "Park La Brea $3.5 million settlement is healthcare precedent." Disconfirmed. Park La Brea (Los Angeles Superior Court, December 14, 2017, $3.5 million awarded across 16 plaintiffs in 8 multifamily housing units) was a multifamily housing case under landlord premises liability, not a healthcare case.
• "Sheele et al. 2017 was published in PNAS." Disconfirmed. Sheele et al. 2017 was published in Infection Control and Hospital Epidemiology (ICHE) 38(5):623-624. The Proceedings of the National Academy of Sciences (PNAS) published a 2019 commentary by Scarpino and Althouse that derived per-infestation figures from Sheele 2017; the PNAS commentary is a secondary citation, not the primary data publication.

AHRQ Common Formats Claim

• "AHRQ Common Formats include an 'Environment' event-type category within the Patient Safety Event reporting framework." Disconfirmed. CFER-H V2.0 (current as of 03-31-2025) modules are Anesthesia, Blood, Device, Fall, Medication, Perinatal, Pressure Injury, Surgery, and VTE. CFS-H V1.0 modules add Birth-Maternal, Birth-Neonatal, Hospital-Acquired Infection, and Other. No "Environment" or equivalently-named event-type category exists.

State Citation Claims

• "Utah school IPM rule is codified at R392-200-7(12)." Disconfirmed. The Utah school IPM rule is at R392-200-18 "Pest Management."

BCE Credential Claims

• "BCE is a graduate-level credential." Disconfirmed. BCE requires a bachelor's-level degree in a biological or life science with at least four entomology courses. Advanced degrees satisfy the educational requirement but are not required.

Verification Discipline

Foundation content for this reference was produced through seven research threads followed by five validation rounds. Each validation round targeted specific factual claims from prior research and re-verified them against primary sources via live web fetch where the primary source was publicly accessible, or via cross-referenced secondary aggregators where the primary source was paywalled or rendered in JavaScript.

The validation discipline was intentionally adversarial: every claim was treated as potentially fabricated until verified, and verification required direct primary-source confirmation rather than secondary or tertiary citation. This methodology surfaced multiple fabricated claims in prior research outputs, all catalogued above and excluded from the reference.

Ongoing maintenance follows the same discipline. New authority pages are added only after primary-source verification. Existing pages are re-verified at least annually or upon any reported change to the underlying authority.
