Imagine what the laws are like

That's what they say, you know: The two things you never want to watch being made are laws and sausages.

“Cervelas is the Swiss national sausage,” said Mr. Büttiker....

The name cervelas — Switzerland’s jumble of languages yields other spellings, including cervelat, zervelat and servelat — is derived from cerebellum, Latin for brain, since the sausage originally consisted of pork and pigs’ brain. Today, it is made of beef, bacon and pork rind, mixed with ice to cool it during mincing; it is lightly smoked and briefly boiled.

The use of zebu intestine as a casing is actually a child of mass retailing and the need of supermarkets for cervelas that were alike in color, size and flavor. But it was also a result of the rising cost of cattle intestines in Switzerland, where farmers were increasingly unwilling to clean the innards of their slaughtered cattle for the sausage industry.

They do taste good though so that's something, anyway.
