Claim summary · not a verbatim quotation
90% of BSL-3 laboratories worldwide operate without safety guidelines.
The finding
What the evidence shows
There's a real problem here, but not the one this specific number describes. A recent academic effort to map biosafety labs worldwide found genuine gaps in oversight, especially in lower income countries, but it doesn't turn up a figure showing 90% of BSL-3 labs specifically lack safety guidelines. The claim borrows a real concern and turns it into a precise statistic that doesn't actually show up in the research.
