The lesions in rumens of goats with soft foreign bodies (SFB), namely plastics, and its prevalence in Jordan are investigated. In cases where hard masses of plastics were seen, congestion, erosions, focally denuded areas and focal thickening of nodularand proliferative-type were seen in the mucosal wall of the rumen. Shortening and stunting of the papillae with irregular distribution, and in some cases thinning of the walls were also observed. Histopathologic examination revealed the presence of rumenitis and prolonged rete pegs with a papillary or frond-like downward growths. This hyperplastic growth also took the shape of numerous epithelial islands of variable thickness, approaching the muscularis mucosae. These revealed differentiated stratified squamous epithelium with intercellular bridges, keratin formation and with several mitotic figures as seen under a high-power field (40x). In cases where floating plastic was found, the changes were less prominent. These findings suggest that plastics play an important role in the pathogenesis of rumenitis and ruminai hyperplasia. This could be the consequence of partial degradation and/or chronic irritation of plastics. Out of 347 rumens examined in the summer of 1996, 39 (11%); 10/136 (7%) rumens at Ajloun and 29/311 (7%) at Irbid slaughterhouses contained plastics. Out of the 888 goats brought to the Veterinary Health Centre (VHC) from January 1993 to September 1997 for treatment of different conditions, 32 (3.6%) had plastic impaction and were treated by rumenotomy of which 32/722 (4.5%) were older than one year. Out of 28 goats brought dead to VHC for routine necropsy examinations, three goats had plastic impaction. No significant differences were found in the prevalence of plastic among Shami, local and mixed-breed goats. These results suggest that subclinical cases exceed clinical ones. The prevalence, although when compared with our previous results in sheep, is low, yet it is still considered quite high and public awareness and anti-littering laws and a clean-up of the environment would substantially reduce this problem in Jordan.
