At the same time, the 15,000 litre claim also averages out the blue water part, which, as Tim said earlier, can range from less than 100 litres to many thousands.
The average is about 500 litres, but that hides the bit that potentially matters most in terms of the impact on water supplies.
All of which means you can't use the global water footprint to say that beef is bad.
And when Mesfin sees his numbers used like that, it makes him uncomfortable.
That's it for this week.
Thanks to Mesfin Meekinen, Mark Mulligan and Tim Hess.
If you've seen a number you think we should take a look at, email us on moreorless at bbc.co.uk.
Until next time, goodbye.
We're the programme that looks at the numbers in the news, in life and in surveys.
Yeah, often they're from surveys.
I'm Charlotte MacDonald.
Vaccine policy in the US is something of an ideological battleground.
Health Secretary Robert F. Kennedy Jr.
is a vaccine sceptic.
And since taking office, he has attempted to remake US vaccine policy.
In March, a judge blocked his proposal to cut the number of jabs that are recommended for kids.
At the same time, last year saw the worst measles outbreak in the US in decades.
There were more than 2,000 cases last year and three people died.
There have been more than 1,500 cases so far in 2026.
There's a lot going on, so it's possible the public's views on vaccination are shifting.
