Argus analysis
PLZ Corp (MARCS-CMS 721140, FEI 3001956890) received an FDA Warning Letter dated June 2, 2026 from the Center for Drug Evaluation and Research (CDER). The letter cites: CGMP/OTC Finished Pharmaceuticals/Adulterated. FDA posts Warning Letters to fda.gov after an internal review period; this one was made public on June 9, 2026.
Nonprescription/OTC letters typically cite the relevant OTC monograph under 21 CFR Part 330 (or the newer OTC monograph order process under the CARES Act) alongside 21 USC 352 misbranding provisions. Common findings involve active ingredients, dosing, or labeling claims that fall outside the applicable monograph's permitted conditions.
FDA Warning Letters typically specify a 15-working-day response window for the recipient to detail corrective actions. Compliance teams at peer companies in the same CGMP (Current Good Manufacturing Practice) category commonly use a newly published letter as a prompt to re-check their own procedures against the same citation, and to watch fda.gov for a close-out letter confirming the cited firm's corrective action was accepted — or, absent one, for escalation to import alert, injunction, or product seizure.
Severity context
High severity. Typically QSR / device CGMP, adulterated-drug, or significant labeling matters — usually drives a documented corrective and preventive action (CAPA) program.
Regulatory background
CGMP citations typically reference 21 CFR Part 211 (drugs) or 21 CFR Part 600 (biologics). Common subjects include identity testing of incoming components (211.84), validated cleaning procedures (211.67), and stability program design (211.166).
What peer compliance teams typically do next
Most compliance officers at peer companies use a Warning Letter against a named entity as a checklist for their own CAPA program. Common steps: pull the verbatim FDA letter; map each cited 21 CFR section against the team’s SOP library; confirm CAPA coverage; brief the QMR (Quality Management Review) on whether the cited subject matter is in scope for the next internal audit. The 15-business-day response window applies to the cited entity, not to peers — but a documented internal review against the cited subjects is what regulators expect to see if a peer is later inspected on the same topic.
Excerpt from the FDA Warning Letter (public domain, 17 USC §105)

FDA has reviewed the records you submitted in response to our September 8, 2025 request for records and other information pursuant to section 704(a)(4) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) for your facility, PLZ Corp, FEI 3001956890, at 6080 Vipond Drive, Mississauga, as well as subsequent correspondence. This warning letter summarizes significant violations of Current Good Manufacturing Practice (CGMP) regulations for finished pharmaceuticals. See Title 21 Code of Federal Regulations, parts 210 and 211 (21 CFR, parts 210 and 211). Because your methods, facilities, or controls for manufacturing, processing, packing, or holding of drugs as described in your response to our 704(a)(4) request do not conform to CGMP, your drug products are adulterated within the meaning of section 501(a)(2)(B) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 351(a)(2)(B)). Following review of records and other information provided pursuant to section 704(a)(4) of the FD&C Act, significant violations were observed including, but not limited to, the following: 1. Your firm failed to test samples of each component for identity and conformity with all appropriate written specifications for purity, strength, and quality (21 CFR 211.84(d)(1) and 21 CFR 211.84(d)(2)). Your firm manufactured (b)(4) , an OTC (b)(4) drug product labeled to contain the active drug ingredient (b)(4) . This drug product is labeled and formulated to contain the inactive ingredient talc. Both talc and asbestos are naturally occurring minerals that may be found in close proximity in the earth. Asbestos is a potential contaminant in talc and is a known human carcinogen when inhaled. 1,2 Your (b)(4) drug product, (b)(4) , is considered a higher-risk drug as it pertains to patient safety regarding asbestos contamination of talc due to the risk of inadvertent inhalation. You have not demonstrated that you appropriately tested incoming talc drug components used in the manufacture of (b)(4) drug products for identity, purity, strength, and quality. In response to our 704(a)(4) request, you originally indicated that you did not perform testing for asbestos in talc before release for use in drug product manufacturing. In subsequent correspondence, you indicated that you had tested and that your initial response was erroneous, but the data you provided only clarified that your talc compone…
