More than 300 sites in Western Hungary were identified this year where roads and public spaces were surfaced with asbestos-contaminated crushed stone originating from Austria.

Omissions

• The 'around 300' figure published in May 2026 refers to sites the authority counts as 'potenciálisan érintett' (potentially affected) in the three western counties (Vas, Zala, Győr-Moson-Sopron), not to a definitive tally of confirmed asbestos-contaminated sites; the claim's wording 'azonosítottak' (identified) and 'more than 300' is a slight shift from the source's 'mintegy 300' (approximately 300) 'potentially affected'.
• The sources found are dated May 2026, several months before the 17 September 2026 session; the number could plausibly have grown beyond 300 by the session date, which would make the claim accurate, but no source confirming a figure above 300 was located.
• A separate and larger figure circulating in the same coverage refers to more than 250 municipalities that received crushed stone between 2015 and 2026 (a different metric from the number of affected sites).
• Only secondary (journalistic) sources citing the authorities were found; no primary official dataset or ministry publication stating the exact number of affected sites could be retrieved.
