Prosciutto: Nutrition, Sodium and What Prosciutto di Parma Means

Prosciutto is an Italian salt-preserved leg of pork, aged for months and eaten uncooked in paper-thin slices. USDA’s food database has no entry for prosciutto itself, so this guide uses the closest labeled entry, an uncooked, dry-salted country-style ham. It covers what prosciutto is, what the Prosciutto di Parma rules require, its nutrition, what WHO says about processed meat, nitrite labels and food safety.

Peptide Labs does not sell prosciutto or any meat products. This article is general nutrition information, not medical advice.

What is prosciutto?

Prosciutto is the Italian word for ham, and in English it usually means prosciutto crudo: a whole leg of pork that is salted, rested and air-dried for many months, then sliced very thin and served raw. The long, slow drying gives prosciutto its silky texture and deep pink color.

That makes it quite different from the cooked ham sold for sandwiches and holiday dinners. Our ham guide covers those products, and our bacon guide and pork guide cover the rest of the pig. A similar American product is country ham, which federal rules (9 CFR 319.106) describe as uncooked and made by the dry application of salt.

Prosciutto di Parma: what the PDO label requires

Prosciutto di Parma is a protected designation of origin (PDO) under European Union rules. The Parma Ham Consortium says it was one of the first meat products to receive that status, in 1996, and that the only ingredients its production specification allows are pork and salt. The current specification, consolidated in May 2025, sets out the main rules:

• Origin of the pigs: the pigs must be born, bred and slaughtered in one of 11 Italian regions named in the specification, including Emilia-Romagna, Lombardia, Veneto and Piemonte, and be at least nine months old.
• Production area: under the specification, salting, ageing, slicing and packaging must take place in a defined part of the province of Parma, south of the Via Emilia, bounded by the Enza and Stirone rivers and below 900 metres of altitude.
• Salt only: the specification says salting is done exclusively with sea salt, that no chemicals, preservatives or other additives are used, and that the legs are not smoked.
• Ageing: the specification’s minimum ageing time is 14 months.
• The crown: after inspection, each ham is fire-branded with the five-pointed ducal crown logo; under the specification, a ham without it cannot be sold as Prosciutto di Parma.

The specification reserves the name exclusively for hams that meet these rules, so a product labeled simply prosciutto, including one made in the United States, is not Prosciutto di Parma.

Prosciutto nutrition (USDA SR Legacy)

USDA SR Legacy has no entry named prosciutto. The nearest labeled entry is raw country-style ham, center slice, lean only (FDC 168282), an uncooked, dry-salted ham. Because it is lean only, its fat is likely lower than a prosciutto slice eaten with its rim of fat. The table shows that entry per USDA ounce and per 100 g, next to regular unheated ham with lean and fat (FDC 167875) for comparison. Percent Daily Values (%DV) use FDA reference amounts.

In this USDA entry, one ounce of dry-salted ham supplies 16% of the Daily Value for protein, with almost no carbohydrate, along with thiamin and selenium. USDA pork entries list notable amounts of thiamin; our thiamin foods guide shows how it compares with other foods.

The number that stands out is sodium. The same ounce lists 764 milligrams of sodium, 33% of the Daily Value, and 100 g lists more than a full day’s Daily Value. FDA explains that 20% DV or more of sodium per serving is considered high and that over 70% of dietary sodium comes from packaged and prepared foods. For Prosciutto di Parma, the specification itself sets an accepted salt range of 4.2% to 6.0% in the lean meat it tests. Our low-sodium foods guide explains how to read sodium on labels.

Is prosciutto healthy? What WHO says about processed meat

Whether prosciutto is healthy depends partly on how it fits with the rest of what you eat, but two official statements apply directly. First, WHO defines processed meat as meat that has been transformed through salting, curing, fermentation, smoking or other processes to enhance flavor or improve preservation, and prosciutto is made by salting and air-drying.

WHO’s cancer agency, IARC, classified processed meat in Group 1, carcinogenic to humans, in 2015. WHO explains that Group 1 is used when there is sufficient evidence of carcinogenicity in humans, and that for processed meat the evidence shows it causes colorectal cancer and suggests a link with stomach cancer. Group 1 describes how strong the evidence is, not how large the risk is for any one person; IARC said in 2015 that the individual risk remains small but increases with the amount eaten. WHO says the data did not allow a conclusion about whether a safe level exists, and that it is developing a guideline that will include recommendations on red and processed meat.

The Dietary Guidelines for Americans 2025-2030 advise eating meat with no or limited added sugars, refined carbohydrates or starches, or chemical additives, and state that highly processed foods high in sodium should be avoided. They also say saturated fat should generally not exceed 10% of total daily calories. A doctor or registered dietitian can help you apply them to your own diet.

Nitrite, nitrate and uncured labels

Under federal rules (9 CFR 317.17), any curing substance, such as salt, sugar, sodium nitrate or sodium nitrite, must be listed in the ingredients statement. 9 CFR 424.21 lists nitrite as an ingredient used to fix color, caps it in finished products, and does not allow it in baby, junior or toddler foods.

A product made without nitrate or nitrite may be labeled uncured, and it must then also say No Nitrate or Nitrite Added. That wording can include products made with natural nitrite sources such as celery powder; USDA’s Food Safety and Inspection Service (FSIS) said in a 2020 letter that it intends to propose changing those claims for such products. Prosciutto di Parma is a separate case: its specification allows only pork and sea salt. For any other prosciutto, the ingredient list on the label is the place to check.

Listeria and who should heat prosciutto first

Prosciutto is eaten without cooking, so CDC’s Listeria guidance applies. CDC lists four groups at higher risk of serious Listeria illness: people who are pregnant, newborns, adults 65 or older and people with a weakened immune system. CDC advises these groups to avoid unheated deli meat and cold cuts and to eat them only when reheated to 165 F or until steaming hot. FDA notes that pregnant women are about 10 times more likely to get listeriosis than other healthy adults. Our deli meat guide covers this advice in detail.

For prosciutto, heating it as CDC describes usually means crisping it: bake slices on a tray until they are sizzling and crisp, or cook them into pasta, eggs or a pizza until steaming hot.

Allergy notes

• Major allergens: pork is not one of the nine major food allergens that US labels must declare, although any food can cause a reaction in some people.
• Alpha-gal syndrome: CDC describes alpha-gal syndrome as a serious, potentially life-threatening allergy linked to tick bites, most often the lone star tick in the United States, and says people with it may need to avoid red meat, including pork.

How to serve prosciutto

• Slice thin: prosciutto is meant to be nearly translucent; have it sliced fresh at the counter or choose presliced sealed packs.
• Serve near room temperature: take it out of the refrigerator shortly before serving so the fat softens and the flavor opens up.
• Classic pairings: wrap it around melon such as cantaloupe, fresh figs or breadsticks, or serve it with Parmesan.
• Cooked uses: crisp it in the oven as a topping for salads and soups, or add it to pasta and roasted vegetables.
• On pizza: lay it on after baking for a silky texture, or before baking for a crisp one.
• Store: keep it refrigerated and wrapped tightly, and follow the package date.
