Airlines often boast about offering fresh gourmet meals, but one meat dish being served up in business class on British Airways is so fresh, they warn it may contain fragments of ammunition.
Passenger Dr Michael Brown posted a photo of the menu on Twitter in disbelief.
"You've got to be kidding me. From the British Airways in-flight menu from London to Chicago," he tweeted.
His tweet got mixed responses, some seeing the funny side.
Jan Steuart said the chef was "just adding iron", while others used the incident to make a political statements about gun control.
"Looks like British Airways will go the extra mile to make their American customers feel at home," said one Twitter user.
Speaking to The Sun, a spokesperson for British Airways said the warnings are commonplace.
"These warnings are there as a precaution. We source the best British ingredients for our in-flight menu and this is no exception."
Mr Brown decided against ordering the venison stew with rosemary dumplings, roasted chestnuts and wilted kale, opting instead for something of a different caliber.
