Italian blue crabs are becoming increasingly infected with parasites

An invasive species of blue crabs from the Atlantic Ocean is causing concern in Italy due to a parasitic infection that poses a threat to the ecological environment and fisheries. The parasite, Hematodinium, spreads among crustaceans, making the crab meat bitter and difficult to consume. The infection rate among blue crabs in Emilia-Romagna is particularly high at 97%. The parasite does not affect human health but can lead to health risks if blue crabs are eaten raw or undercooked. Researchers are still investigating the potential wider impact of this parasitic infection in blue crabs.
