Alert: Pineapples and pineapple "packed in it's own juice"?

As is well known, Pineapples do have insects in the crown and in the brown parts of the skin peel.

Some Pineapples were found to have have mealybugs  past the brown area as well, it must be checked by experts in infestation.

Now it was discovered another insect issue with canned pineapple. "Packed-in-its-own-juice". The canned pineapple is raw not cooked, how do they get the "Packed-in-its-own-juice"?

They take the skin / peel, etc with all of the inherent insects and cook it to obtain the pineapple-juice.

Is the somewhat viscous juice filtered? If yes, with what size filter?
We asked some of the heimish certifiers and they refuse to respond.
