Well I will be surprised if there has been a post like this before - but according to the cabin crew this morning this has happened a number of times.... Hmm...

We have just returned from our first First trip, and come back on the overnight flight from Rio.

My wife ordered the peach & passionfruit smoothie with her breakfast this morning.... and a glass allegedly containing this was swiftly delivered.

She took one gulp of this and nearly vomited. Passed it to me and I took one closer look and we both clicked that this was a glass of what we thought was raw eggs.

Instantly called the crew over, who inspected, and apologised profusely saying that it is because the cartons that are loaded on containing the egg mixture is the same as that of the smoothies. They then explained that in fact this is a pasteurised egg mixture and therefore hopefully shouldn't make my wife ill.

Suffice to say we did not want to eat our breakfasts due to feeling quite nauseous, which is still on-going for my wife (after a connecting flight and now arriving back home).

Speaking at length with the crew more than one of them gave the impression that this is almost a regular occurrence, due to the cartons being so similar... Something that I am shocked and concerned about.

The CSM was very apologetic about this incident, and initially offered us a bottle of champagne to take off with us - since we were connecting we couldn't do this anyway. He then said he was logging everything on his iPad and would see what compensation he could offer - he came back to say he could offer us a £75 voucher or 17k avios.

After a lengthy chat about the health implications of this we agreed that this was not satisfactory, and he was sending all the details to customer services to see where we go.

Suffice to say this completely ruined our First experience on the return, and my wife is feeling very nauseous still now. Hopefully she will not develop gastroenteritis or anything more sinister, but even if she does now, I would like to know what the FT community think about this incident.... Surely this cannot be a regular occurrence?! And what would be an acceptable compensation do people think?

Thanks
