Among the workers in a rubber plantation in South India, ingestion of formic acid either accidentally or with suicidal intention is a common problem. Formic acid is diluted and used for coagulation of rubber latex. Easy availability makes formic acid a common poison. The aim of this article is to study the case of formic acid poisoning, its complications and management. Patient was managed symptomatically. Antidote was not used and no nasogastric aspiration was done. Patient had dysphagia; nutrition was maintained with open gastrostomy done on day 5 and subsequent enteral feeding. Measures to prevent anticipated complications were undertaken. Stricture of the esophagus is a common complication leading to long-term morbidity. After initial management, all patients should be on follow-up for prevention and management of strictures. Workers should be educated on complications of formic acid poisoning and easy availability should be curtailed by enforcing remedial measures.
