Shrimp are slaughtered using methods that may cause significant suffering, with ice slurry and boiling being the most common practices.
The welfare of shrimp at slaughter is uncertain but deserves precautionary consideration given the scale of production and emerging evidence for nociception. If shrimp experience something analogous to pain during slow ice chilling or boiling, the total suffering involved is vast. Developing and adopting rapid stunning methods is a low-cost welfare improvement with potentially enormous impact.
