Spectators will not be allowed to carry reusable water bottles into World Cup venues owing to safety concerns, Fifa has said, after a last-minute change to its stadium code of conduct.

The governing body had earlier permitted empty, transparent, reusable plastic bottles inside stadiums but said the updated code prohibited that. Other items such as bottles, cups, jars and cans are also banned to prevent the risk of injury if thrown.

“Fifa is committed to protecting the health and safety of all players, referees, fans, volunteers, and staff,” it said. “Fifa made the decision to prohibit bottles to prevent risk and injury to players and attendees.

“Outside bottles are already prohibited at several of these venues for safety considerations and Fifa is applying this consideration across its tournament stadiums.”

The move has raised concerns among supporters about coping with heat, with temperatures at a few venues expected to range between 26C and 28C, and access to drinking water inside stadiums.

Fifa said measures would be in place to deal with the conditions. “Fifa works closely with each host city committee and local authorities on heat mitigation factors for fans travelling to the stadium, which can include resources such as misting stations, fans, hydration stations, cooling tents and more around the stadium footprint,” it said.

“Inside the stadium footprint, pricing for water bottles for the Fifa World Cup 2026 will remain consistent with other events held at each stadium.”

The Free Lions England fans’ group posted on X: “What next? Sun cream banned and fans forced to buy it in stadiums? For all of the effort they are going to with ‘drinks breaks’ for the players, this is such a strange, late change.

“In all of our discussions, free water availability in stadiums was a key one and we were assured by Fifa that this would be the case and that fans will have the ability to bring their own water bottle.

“Naturally, the immediate thought from supporters is this is just the latest money-grab. For how hot the stadiums will be, many in open air, just let fans bring a bottle if they want to. We hope the water fountains in stadiums will still be free, hopefully you aren’t charged in the queue!”

The 48-team World Cup, co-hosted by the US, Canada, and Mexico, will run from 11 June to 19 July.
