Polarization score: 2/5

The outlets show moderate framing differences but not ideological polarization. The divergence is mainly journalistic—some outlets emphasize the FDA's error while others emphasize the ongoing investigation. This reflects editorial choices about what aspect of a food safety story to lead with rather than partisan divides.

The core difference is whether outlets frame the false positive as the main story (Guardian, NBC News) or as a secondary detail within the larger narrative that Taylor Farms remains under suspicion (Politico, Axios). The Guardian and NBC lean toward the 'FDA made a mistake' angle, while Politico and Axios emphasize that the investigation's conclusions remain unchanged despite the lab error.
