Africa-Press – Burkina Faso. <\/strong><\/span>Les preuves s’accumulent concernant la sensibilite\u0301 des crustace\u0301s a\u0300 la douleur. Avec pour conse\u0301quence directe que des pays tels que la Norve\u0300ge, la Nouvelle-Ze\u0301lande et l’Autriche ont interdit de les cuire vivants. L’industrie re\u0301fle\u0301chit aussi de son co\u0302te\u0301 a\u0300 un moyen de cuire ces animaux tout en limitant leur douleur. L’une des pistes e\u0301voque\u0301es est le choc e\u0301lectrique, afin de leur e\u0301tourdir pre\u0301alablement.<\/p>\n

Une nouvelle e\u0301tude publie\u0301e le 13 avril 2026 dans la revue Scientific Reports de\u0301montre que la me\u0301thode peut se re\u0301ve\u0301ler tre\u0300s douloureuse pour les langoustines communes. En effet, des chercheurs de l’universite\u0301 sue\u0301doise de Go\u0308teborg ont notamment observe\u0301 que lors d’un choc e\u0301lectrique de\u0301livre\u0301 dans l’eau, ces crustace\u0301s agitent fre\u0301ne\u0301tiquement leur queue, signe qu’ils tentent d’e\u0301chapper a\u0300 un danger.<\/p>\n

L’aspirine et la lidocai\u0308ne efficaces<\/b><\/p>\n

Cependant, les scientifiques ont aussi de\u0301couvert un moyen de limiter cette douleur. En effet, ils ont remarque\u0301 que des traitements antalgiques normalement utilise\u0301s en me\u0301decine humaine, permettaient, lorsqu’ils e\u0301taient de\u0301livre\u0301s avant le choc e\u0301lectrique, de diminuer ensuite les mouvements de la queue. Plus pre\u0301cise\u0301ment, ils ont teste\u0301 l’aspirine – un antalgique – et la lidocai\u0308ne, un anesthe\u0301sique local ayant des proprie\u0301te\u0301s analge\u0301siques.<\/p>\n

L’injection du premier traitement a conduit les langoustines a\u0300 toiletter leurs pattes et leurs griffes, ce qui signifie que l’animal est stresse\u0301. Cependant, les mouvements de la queue e\u0301taient beaucoup moins nombreux qu’auparavant lors du choc e\u0301lectrique. Quant a\u0300 la lidocai\u0308ne, dissoute dans l’eau, elle a e\u0301galement re\u0301duit les mouvements de la queue et ne semblait pas conduire a\u0300 des effets secondaires, ce qui fait d’elle une candidate particulie\u0300rement inte\u0301ressante.<\/p>\n

\u00ab\u00a0Notre fonctionnement est similaire\u00a0\u00bb<\/b><\/p>\n

Pour les chercheurs de l’Universite\u0301 de Go\u0308teborg, cette de\u0301couverte illustre une nouvelle fois la sensibilite\u0301 de ces crustace\u0301s a\u0300 des stimuli douloureux. \u00ab\u00a0Le fait que les analge\u0301siques mis au point pour les humains fonctionnent e\u0301galement sur les langoustines montre a\u0300 quel point notre fonctionnement est similaire, remarque dans un communique\u0301 la professeure Lynne Sneddon. C\u2019est pourquoi il est important de se soucier de la fac\u0327on dont nous traitons et tuons les crustace\u0301s, tout comme nous le faisons pour les poulets et les vaches\u00a0\u00bb.<\/p>\n

Selon la chercheuse, cette e\u0301tude ne devrait pas uniquement servir l’industrie. Le traitement de la douleur des crustace\u0301s est aussi a\u0300 prendre en compte dans la recherche, lors de proce\u0301dures invasives. \u00ab\u00a0Cette e\u0301tude peut contribuer a\u0300 rendre les expe\u0301riences plus douces pour les animaux gra\u0302ce a\u0300 l\u2019utilisation d\u2019analge\u0301siques\u00a0\u00bb, remarque-t-elle.<\/p>\n
