🥓 Cured meats & charcuterie

Cured meats & charcuterie (М'ясні делікатеси; also cured meats, charcuterie, salumi) are meat products that keep for a long time thanks to salt, drying and sometimes fermentation: hams, dry-cured sausages, salo. Under EU law a «meat product» is processed meat whose cut surface no longer shows the traits of fresh meat (Regulation 853/2004, Annex I, point 7.1).

Pork was being salted in Spain as far back as Roman times: the oldest written references date to the late 2nd century BC (EU Official Journal C 371/1998). According to FAO, dry sausages have been made for centuries in moderate climates, usually in the cold season, and before refrigerators they served as a protein reserve. Parma ham has had legal protection since 1970, and the name Prosciutto di Parma has been protected in the EU since 1996.

This theme covers only what keeps well: either shelf-stable at room temperature, or good for more than 7 days chilled. Cooked sausages and frankfurters are left out. Spanish law draws a similar line: «curado-madurado» products are stable at room temperature, while «oreados» (air-cured) ones generally need refrigeration (Real Decreto 474/2014).

So why does salt make meat keep? It hardly kills bacteria at all; it binds water. Once water activity drops below 0.91, roughly 15 % salt in the product, microbes stop growing (FAO). Nobody could eat that much salt, so it works together with drying, acidity and nitrite. Processed meat usually holds 1.5–3 % salt, a finished dry sausage 3–4.5 %. Salt and nitrite are covered in Curing of meat.

The raw material is mostly pork and beef, less often other red meat, poultry or offal (IARC). For raw fermented sausages FAO also allows horse, sheep and goat, and the fat is mostly firm pork back fat. In the end, the animal behind most of it is the pig.

FAO sorts meat products into six technology groups, and three of them belong here: cured-raw cuts, raw fermented sausages and dried meat. A ham is cured with salt that is 99.5 % table salt plus 0.5 % sodium nitrite, applied dry, as brine, or both. Dry salting runs at 0 to +4 °C, brine holds 15–20 % salt, and the biggest piece needs about 2 days per kilogram. Then the ham dries and matures, usually for 3–6 months, some kinds for up to 24. That is how you get Dry-cured hams and shoulders, Jamón, Prosciutto crudo, Prosciutto di Parma, Jabugo.

Sausages take another road. Lean meat and fat are chopped, 2.6–3.0 % salt, sugar and a starter culture go in, and the mix is stuffed into a casing. In 5–6 days lactic fermentation brings the pH down to 4.9–5.4, then the sausage dries: most are ready in 3–4 weeks, the thickest take up to 90 days. Less than 35 % water remains, and the product counts as stable even at higher temperatures. See Dry-cured sausages and Salami. Salo stands apart: pig subcutaneous fat salted for 14–16 days at +2 to +4 °C.

Cooked sausages, frankfurters and mortadella are heated; cured raw products never are, and you eat them raw. Dried meat (jerky, biltong) is simply dehydrated, with no fermentation. Semi-dry sausages (summer sausage, cervelat) are moister: at least 40 % water, a shelf life of up to a month, and storage below 18 °C is advised.

On the shelf a protected name is easy to spot by its PDO, PGI or TSG logo. The eAmbrosia register lists 211 names in the class «meat products (cooked, salted, smoked, etc.)»: 37 PDO and 174 PGI, most of them in Italy (45), Portugal (42), France (26), Germany (20) and Spain (19). In the ingredients look for salt and nitrite (E250) or nitrate (E252); some products use salt alone, like Prosciutto di Parma: pork and sea salt. And a grey or white powdery coat on a dry sausage is usually noble mould.

FAO treats a whole, unopened dry product as stable at room temperature. Industrial makers hold dry sausages below 20 °C at 75 % humidity and recommend keeping semi-dry ones below 18 °C or chilled. Bear in mind these are production norms, not kitchen rules.

Why does this matter to you? IARC (WHO) classes processed meat in Group 1, carcinogenic to humans: each 50 g eaten daily raises colorectal cancer risk by about 18 %. For an individual the risk stays small and grows with the amount eaten. Once you know how a product is made, the label starts to make sense: salt, nitrite, ageing time, protected name.
