A Scutariella identification case is not a fenbendazole protocol

The evidence library is allowed to change in public. This page preserves the revised boundary, why it moved and which guides were affected.

What changed

The health and quarantine boundary now includes an open captive N. davidi case series with live-worm morphology, visible counts and branchial-chamber eggs.

Why it changed

All 15 selected diagnostic shrimp carried morphologically identified S. japonica, but the paper measured no prevalence, transmission, host harm or treatment outcome. Its fenbendazole statement has no dose, exposure, control, efficacy, recurrence or safety data and cannot become a community treatment recipe.

Affected practical guides

A public change is not automatically a retraction. A source may be added, a scope narrowed, a gap refined or an error corrected. The current guide and registry record own the current wording.
