A truck hauling 21 rhesus macaques overturned on a Mississippi interstate, killing five animals and leaving three at large, authorities said. Tulane University said the monkeys had been housed at its National Biomedical Research Center but declined to identify the owner or shipping company. The incident exposed gaps in transparency around the transport, ownership and research uses of nonhuman primates. Local searchers in protective gear recovered crates and conducted field searches; early sheriff statements referenced disease concerns that Tulane later said were unfounded. Animal‑welfare advocates and legal experts pressed for disclosure of the transporter, destination and research purpose, arguing communities have a right to know public‑safety and biosecurity risks. The crash stresses compliance and oversight issues for institutions that rely on animal models: universities and private contractors must balance transparency with proprietary research relationships, while state regulators, institutional animal care and use committees (IACUCs), and transporters face scrutiny over containment, labeling and emergency response procedures.
