00:00This cheese is not for the faint of heart.

00:04That's because casu marzu is laced with maggots.

00:11I like it with lots of maggots in it, but also with few.

00:14The more maggots, the more intense.

00:18The cheese is as strong as the people who live here.

00:21Strong as granite.

00:25Casu marzu can actually be harmful to your health.

00:28If the maggots are still alive, they can damage the digestive tract.

00:32But that won't stop its fans from indulging in it.

00:36There's nothing dangerous about it.

00:38Nothing at all.

00:39It's a completely natural product.

00:43Still, the sale of casu marzu is strictly forbidden.

00:47So, who produces it and why?

00:51We're on the Italian island of Sardinia,

00:54which is known for upholding all kinds of old traditions.

01:00Farming here revolves mainly around sheep,

01:03which provide milk for the island's trademark cheese, pecorino.

01:08We'll see how pecorino becomes casu marzu in a moment.

01:14There are around three million sheep on Sardinia,

01:17mostly Pecora sarda, a breed that produces a lot of milk.

01:24It's tradition, our culture.

01:27There are a few cows in Sardinia,

01:29but it's the sheep that really belong here.

01:35At Fattoria Istentales, a small cheese dairy,

01:39cheeses are still handmade every day in keeping with tradition.

01:44First, the milk is heated to 36 degrees Celsius.

01:48Then, rennet is added,

01:50which provides the enzymes needed to turn milk into cheese.

01:56It's a hard and exhausting job that is slowly dying out.

02:01Young people, well, they would prefer to do something else.

02:08The first thing I always do is make a cross. It's tradition.

02:12After about an hour, the curd is ready.

02:15It is then heated again and filled into molds,

02:18followed by a few squeezes to remove any excess whey.

02:23It's a process that requires skill and a great deal of care.

02:28Finally, the fresh cheese is placed in a salt bath.

02:33After six to seven hours,

02:35I can take it out and put it on the shelf to mature.

02:38This is what the pecorino looks like after maturing.

02:41But how does it become casu marzu?

02:46There's a fly that makes the cheese.

02:48It's a small fly, not the kind that flies around your house,

02:51but a cheese fly.

02:55And all it takes is a small crack in the cheese.

02:59The fly goes in, lays its eggs,

03:01and soon the house will be full of cheese.

03:05The fly goes in, lays its eggs,

03:07and soon the hatched maggots eat their way through the inside.

03:13Casu marzu literally means spoiled cheese,

03:15which was once thrown away.

03:17Now it's a Sardinian delicacy.

03:20The maggots out here are already dead.

03:25But to know if the cheese is ready, we have to open it.

03:35Well, it's not quite there yet,

03:37but in here it's already proper casu marzu.

03:42The maggots' hard work digesting

03:44has made the cheese creamier and changed its consistency.

03:53You eat it with the Sardinian bread, pane carasau.

03:57The cheese is spread on top, and now we eat.

04:01Wonderful.

04:03This one is really strong and spicy.

04:06But what's it like if you're not from Sardinia?

04:09Our reporter dared to find out.

04:13Have courage. Relax. It's delicious.

04:20Quite spicy.

04:24It's a little spicy.

04:27Quite spicy.

04:36Some wine with it?

04:40It really has a very strong taste.

04:43I mean, it still tastes like cheese,

04:46but like a very, very strong one.

04:48And I think I should forget about what happened in this cheese,

04:52or I will never eat it again.

04:55For those with a milder palate,

04:57pecorino will be more up your alley.

04:59But for the bold and brave,

05:01casu marzu is a must-try if you get the chance.

05:05It's unmatched.

05:07It's only made in Sardinia

05:09and doesn't exist in any other part of the world.

05:11So you either eat it here or not at all.
