report
Claim 1: “A quarantine zone spanning 20km (12.4 miles) has been established around the affected farm”
MISLEADING
While a quarantine zone was established, the evidence from NBC specifies it was a 12-mile zone, not 20km (which is ~12.4 miles). However, the claim says 20km (12.4 miles), and NBC says 12 miles. These are nearly identical, but the specific '20km' metric is not explicitly corroborated in the provided snippets, though the 12-mile figure is.
