"The Three Little Pigs" depicts the Big Bad Wolf disguised as a Jewish beggar, complete with a long nose, beard and caftan, as he tries to gain entry to one of the pigs' homes.
The Austria Press Agency says it was seen last week on one of the network's children's programs.
Program director Wolfgang Lorenz expressed his "great" regrets Tuesday that the cartoon was broadcast. He spoke of a slip-up that evaded the "strictest quality criteria," and said he would make sure that "such a mistake ... will not occur again."
Criticism was first voiced by the weekly "Falter" magazine.
