West Ham manager Sam Allardyce has said any fans caught making racist or anti-Semitic chants should be banned for life.
Allardyce was reluctant to condemn supporters after Sunday's game at Tottenham as he had not heard the chants himself but, having seen the footage, he has backed his club's zero tolerance stance.
"I did not agree or disagree with what went on on Sunday, let me make that clear," he told Sky Sports News.
"I was doing a press conference after the game and I had no idea what had happened at the time because I had not heard or seen it as I was concentrating on the game.
"Since the game, it is obviously very disappointing to hear what has been said and done by a very small minority of fans.
"The good thing is with security cameras and CCTV cameras, it's difficult for
them to get away with it. Hopefully we can pick out those people and punish them in the right way.
"Nobody can condone that sort of behaviour and there is zero tolerance of it at this club. The club, Tottenham and the authorities will deal with it accordingly."
Police arrested two fans during the match for making Nazi-style salutes, which officers described as a 'racially aggravated public order offence'.
One of those individuals has been identified by West Ham as a season ticket-holder and has been banned by the club.
"Any other individuals identified can expect a similar swift and robust response," a West Ham spokesman added.
Their defeat against Notts County at the weekend was the Robins' second successive 1-0 loss, leaving them eighth in the League One table.
Paolo Di Canio's side have failed to win any of the 11 games in which they have fallen behind this campaign, and Foderingham admits his teammates need take more of their chances.
He told the Swindon Advertiser: "I can't criticise them too much but we do need the boys to chip in with a few more.
"When they get in the position to score they have to put it in the back of the net.
"We're all down a bit. We need to find a way to turn these chances into goals."
