Elderflower birthday help

[talltom]

Have just run off a batch of elderflower cordial as the non-alcoholic option (to go with alcoholic ginger beer and cider) for a birthday party.

I'm only a week in and have noticed blackcurrant sized, pale, frondy patches floating in the liquid. They are present in all my bottles. The taste is still fine.
I'm guessing this may be a bacterial infection as no sterilisation of the actual elderflowers took place and they were added to a cold mix of sugar, lemons, oranges and citrate (as per recipe).

I'm wondering if this sounds like the case and if a couple of campden tablets after a good seive might be the cure.

Other than offering the drivers water any ideas would be appreciated.

Sounds like bacteria or fungus, but could be natural yeast. Any pressure appearing in the bottles? Might indicate yeast.

Campden sounds good, but can't vouch for how safe gassed mico-beasties are.

its more likely to be yeast ive had this when priming cider after about a week in the fridge it will settle to the bottom
