How thawing on the counter is a different risk from thawing in the fridge

On the counter the surface warms into the growth band while the center is still ice.

From the opening

Thawing on the counter is riskier than thawing in the fridge because the outside of the food warms into the bacterial growth band while the inside is still frozen. In the refrigerator the whole piece can thaw while staying in the slow-growth cold, so the surface never gets that warm interval. The opening covers heat arriving at the surface first, a warm wet layer over a frozen core, and the fridge keeping that layer cold.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
