Heinz let a domain name expire, whereupon the URL fell into new ownership and the link printed on ketchup bottles began sending customers to porn.
A shocked [customer] Daniel promptly turned to Heinz's Facebook page to point out the mixup, writing that "Your ketchup really isn't for under-age people."
"Even if the bottle was a leftover, it's still in lots of households," he went on.
"It's incomprehensible that you didn't reserve the domain [web address] for one or two years. It really doesn't cost the Earth."
Heinz's social media team were instantly apologetic, replying that "we really regret the event very much and we're happy to take your suggestions for how we implement future campaigns on board."
