White slime in PRIME LEMON LIME

While drinking Prime (the green one), I felt something weird in my mouth. When I spit it out, there was some disgusting, slime-like substance.

Feeling unsettled, I checked inside the bottle, and I found this nasty stuff floating around... It’s absolutely revolting.

I bought this in India (I’m currently working here as an expatriate). This Prime was imported into India.
