What does "muscles" mean in this case where an Irish restaurant owner is talking about his restaurant?

Is it a typo of "mussels" or does it mean "workers/labor"?

"We use over 20 different producers here from the craft beers, to the whiskey, to the muscles, to the vegetables, to the meats, the lambs."

"We use over 20 different producers here from the craft beers, to the whiskey, to the muscles, to the vegetables, to the meats, the lambs."

Answer

It appears to be a typo. Since the owner is referring to food in the sentence, I assume the word should be "mussels."
