Study finds evidence that crabs can feel pain
The reserachers recorded brain activity in reponse to both physical and chemical stimuli.
Researchers call for more humane treatment of shellfish. 

Scientists have said that the way shellfish are killed needs to change, following a new study that suggests that shore crabs can feel pain.

Researchers from the University of Gothenburg, Sweden, used EEG-style measurements to test the response of shore crabs to different stimuli.

Although previous observational studies had suggested that crustaceans might feel pain, the researchers were the first to study the brain activity of shore crabs to test for signs that they can feel pain.

Eleftherios Kasiouras, lead author of the study, explained: “We could see that the crab has some kind of pain receptors in its soft tissues, because we recorded an increase in brain activity when we applied a potentially painful chemical, a form of vinegar, to the crab's soft tissues. The same happened when we applied external pressure to several of the crab's body parts”

Although the crabs responded to both forms of stimuli, the researchers recorded a shorter and more intense response to physical stress than chemical stress.

Shellfish are not currently covered by animal welfare legislation in the EU despite being widely used in science and
aquaculture. In the UK, decapod crustaceans such as lobsters, octopuses and crabs were recognised in 2021 as sentient beings under the Animal Welfare (Sentience) Bill.

Lynne Sneddon, zoophysiologist at the University of Gothenburg, said: “We need to find less painful ways to kill shellfish if we are to continue eating them. Because now we have scientific evidence that they both experience and react to pain.”

The study has been published in the journal Biology.

Prof Joanne Webster elected as Fellow of the Royal Society

News Story 1
 Joanne Webster, a professor of parasitic diseases at the RVC, has been elected as a Fellow of the Royal Society (FRS).

An infectious disease expert, Prof Webster is known for promoting a One Health approach to disease control.

She completed her doctoral research in zoonotic disease and parasite-host interactions, and has since earned widespread recognition for contributions to parasitology and global health.

Prof Webster said: "I am truly honoured, and somewhat stunned, to be recognised alongside such an exceptional group of scientists."

Germany FMD import restrictions eased

The UK government has lifted the import restrictions placed on FMD-susceptible commodities from Germany.

The decision comes after the country was recognised as foot-and-mouth disease free without vaccination on 14 May.

Imports of FMD-susceptible animals and their by-products from Germany were originally banned, after the country reported a case of FMD near Brandenburg in January. In March, the UK government permitted imports from outside of the outbreak zone.

Germany will now be able to import FMD-susceptible animals and their by-products into the UK, providing they meet other import conditions.

The decision follows rigorous technical assessment of measures in Germany. Defra says it will not hesitate respond to FMD outbreaks.
