Abstract

Two birds from a zoological collection suffered fatal intestinal obstruction after each ingested single particles of polyacrylamide gel. Polyacrylamide gel, used in soils for gardening and agriculture, exists as small granules in the dehydrated state but expands markedly upon exposure to water. Polyacrylamide gel might, therefore, be an unrecognized hazard for captive and wild birds and other small animals if consumed.
