Batch pathogen

I bought super m milkshakes and out of the six pack all were fine this evening i opened one and i had a sip and immediately began vomiting and not long after inspected it to find it was greyish green the expiry is 2027 and i have since needed to seel medical attention i am unaware if it is an isolated batch incident or factory sealing faliure please be careful buying super m chocolate milkshake
