Due to their unselective feeding habits, cattle may injest a variety of foreign bodies. Heavier metallic objects consumed can become lodged in the [[The Reticulum - Anatomy & Physiology|reticulum]], and may penetrate the reticular wall under the influence of the continuous [[The Reticulum - Anatomy & Physiology#Ruminoreticular contraction|reticular movements]] and forces caused by pregnancy and parturition.

Pathological changes depend on the direction of penetration; this is usually in an anterior-ventral direction. Pyogenic bacteria escape from the [[The Reticulum - Anatomy & Physiology|reticulum]], causing localised peritonitis and local fibrinous adhesions.

Penetration of the diaphragm and pericardium results in [[Pericarditis|pericarditis]]. Penetration of the heart itself results in myocarditis and endocarditis. Penetration of the lungs and pleura can occur resulting in pneumonia and pleurisy.

Penetration of the [[Heart - Anatomy & Physiology|heart]] itself results in [[Myocarditis|myocarditis]] and [[Endocarditis|endocarditis]]. Penetration of the [[Lungs - Anatomy & Physiology|lungs]] and pleura can occur resulting in pneumonia and pleurisy.

Liver and splenic abscesses also occasionally occur following penetration of either organ.
