Post-harvest shrimp handling involves live animals in variable welfare conditions. Humane handling and processing methods reduce suffering in these potentially sentient crustaceans.
Post-harvest shrimp welfare represents one of the largest-scale welfare issues in the food system given the enormous quantities processed annually. If shrimp experience any capacity for suffering, the current scale of welfare-compromising handling practices affects staggering numbers of individuals. Live transport without water causes progressive oxygen deprivation. Mechanical head removal of live shrimp causes direct tissue trauma. Ice slurry chilling at appropriate temperatures provides rapid loss of responsiveness and may represent a more humane approach, though optimal parameters for shrimp remain under research. Developing and implementing humane post-harvest protocols appropriate to the scale of shrimp processing is a significant research and industry challenge.
