The usage of horseshoe crabs in endotoxin testing engages a fancy selection of stakeholder Views and includes several ‘epistemic communities’ Each and every with their own individual shared beliefs, Performing procedures, and standards for assessing validity that guide them to kind unique understandings. Conversations about possibilities to horseshoe crab derived reagents entail significant uncertainties and diverse views, with discussions turning out to be significantly polarized (Visitor, 2019). Krisfalusi-Gannon et al. (2018, p. ten) propose that the motorists for horseshoe crab safety ‘are both environmental and financial.’ This can be true, but They're also social and cultural.
