i. Cracked Seam. This end seam defect is apparent as a fracture in the double
seam (end seam). Foreign material present in the double seam causes the fracture. It
is a critical defect.
During external examination of the can, the veterinary food inspection specialist
a. Pitted Rust. A can which has rust, not removable by wiping with a cloth, is
called pitted rust. It is a major defect. The rusty areas should be examined closely to
be sure the contents of the can are not leaking. When rusty cans start leaking, it is a
critical defect.
b. Dirty Can (Not Clean). A dirty or unclean can is not clean when there is
visible, adhering dirt, filth, grease, or food particles. Cans with a very thin film or grease
that is discernible to the touch but not visible to the eye are considered clean.
