Abstract: Photosensitiiation in New Zealand cattle is of considerable economic Importance, largely because of the incidence of facial eczema. A detailed consideration of facial eczema is outside the scope of this review but several general articles and reviews of aspects of facial eczema are available. More general or detailed accounts of photosensitivity diseases and mechanisims are also available. Known causes of photosensitization in New Zealand cattle other than facial eczema are few and of minor importance. However, each year a considerable number of cases of photosensitization of unknown cause occur, especially in the spring season. The purpose of this review is to describe the general photosensitization phenomenon and its mechanism, to discuss known causes of bovine photosensitization in New Zealand, to list other possible causes and to provide a guide to the investigation of bovine photosensitization under New Zealand conditions.
