I don't have any sources for this, I cant remember where I read it, but Health Canada has an upper limit to the amount of insect matter that is allowed in fruit products such as orange juice.
In other words, trace amounts of insect body parts are probably found in most fruit products. This makes perfect sense since it would be next to impossible to make sure that absolutely no insects are on/in the fruit before it gets processed.
And on a similar note, many red colored drinks (such as fruitopia) are colored using
Cochineal dye which comes from the insect of the same name.
