The record
Commercial Indian talc products sold over the counter were found to contain tremolite asbestos: one of five products in a first group, and six of eight in a second group.
Claim scope
Verbatim counts, by TEM/PLM/electron diffraction/X-ray analysis, that talc products marketed outside the US have tested positive for tremolite asbestos. This is the strongest peer-reviewed support for the international dimension of the story.
What this source does not establish
Does NOT name any brand, and the page must not infer one. Does NOT establish current contamination — the analysis is from a 2019 publication. Does NOT establish the source of the talc: the authors state 'The country of origin in which the talc examined was sourced for production is unknown to the authors.' Does not establish a prevalence rate for the Indian market; 13 products is a small convenience sample and the selection method is not described in the abstract.
Limitations
No risk measure (SMR/RR/OR) — this is a materials-analysis study, not an epidemiological cohort. Under house tier definitions this is peer-reviewed PubMed literature without a quantitative risk measure; if the page's Tier 1 requires a risk measure, classify it as supporting analytical evidence rather than Tier 1. Corroborating context: PMID 38515807 (Dialogues Health, 2023) calls for prohibition of talc-based products in the Indian market.
