How to choose your canned food?
|
|
Choose your canned food with care:
Avoid buying
cans that bulge or swell at one or both ends - this is due to food contamination (Photograph A)
cans dented at seams - this may lead to small leaks and contamination (Photograph B)
cans that show signs of leaking eg stained labels (Photograph C)
rusty cans and cans with rust stained labels - these may be due to pinhole leaks and contamination (Photograph D)
