Both cans are same lot code but one has galvanized looking interior and has a smell I would associate with canned fish. The mango puree itself smells and tastes normal. Even the can that doesn't smell off looks a bit iffy at the seam.
There is another brand with the same issue plus visible corrosion on the rim, and the only other one I've seen is likely worse since the can exteriors are all sticky and dented.
Update: I have emailed what I assume to be the importer. I also found a different brand with the same problem. This one has some of the golen colour at the seam but the galv look plus some darker corroded looking spots elsewhere.
The smell I said I would associate with fish is more of a nasal stinging metallic smell, but the only other thing I have detected that smell in was canned fish. I could be misidentifying it though seeing as I have worked with a multitude of metals in the past and I can't put the name of any specific metals to the smell. I drank some of the mango lassi before rinsing the can and noticing the issue but the metallic smell lingers as an aftertaste for quite some time, becoming more noticable as the mango and yogurt taste fades.
