Abstract
In the course of an investigation into the distribution of immune cells in the porcine cornea, a band-like lesion on the cornea of two-thirds of the eyes acquired from the local abattoir was noted. Histological investigations revealed an area of corneal epithelium debridement with no obvious other pathological changes. Discussions with abattoir staff soon revealed the cause of the lesions to be the scalding process that all pig carcasses undergo immediately post-mortem that serves to remove unwanted hair and reduce skin-dwelling bacterial contamination. We concluded that the band-like opacity was the result of thermal injury to the anterior surface of the cornea between the open eyelids. It is hoped that this short communication will act as a cautionary note to other investigators who currently use or are considering using porcine eyes in research or as a model in surgical training and who may be unaware of the conventional handling procedures in pig abattoirs.
