The emergence of otter attacks in Singapore: A case series and strategies for management

Abstract

Singapore is experiencing an unprecedented increase in the number of smooth-coated otters (Lutrogale perspicillata). Since 2017, the local otter population has more than doubled to at least 170. This has led to an increase in the number of otter-human attacks since 2021.1,2 While common animal attacks like dog bites are well documented with established management, there is a lack of literature studying the outcomes and management of the increasingly common otter attacks in Singapore. To date, there has only been 1 published case report, which documented an attack by local river otters (Lontra canadensis) in Quebec, Canada.3 This letter aims to evaluate 3 relatively recent cases of otter attacks presented at Tan Tock Seng Hospital, Singapore and propose key management strategies in addressing future attacks.
