Meat from Germany

Teewurst / Rügenwalder TeewurstTeewurst

Teewurst is a spreadable raw sausage of finely cut pork, sometimes with beef, cured and stuffed into casing, then ripened only briefly; many are also cold-smoked. It is reddened by curing but barely dried, so it stays soft and is not meant for long keeping. Made in 4 steps over 2 days. The longest step, ripen briefly, takes 2 days (Hulánková R 2025). Lactobacillus curvatus does most of the fermenting.

Recipe

No fixed amounts recordedThe German food code fixes the meat types and minimum protein levels but not the salt or spice amounts.
Pork low in fat and sinew, coarsely defatted pork, lean beef · Rindswurst uses only lean beef and fat[leitsaetze]
Fatty tissue · Fat released from the cut fat coats the meat and makes it spreadable[leitsaetze]
Nitrite curing salt and spices[leitsaetze][mueller2016]

What makes this one different

Teewurst is a spreadable raw sausage, so unlike salami it is only slightly dried. The German food code requires at least 10 % connective-tissue-free meat protein in fine teewurst and 11 % in coarse teewurst.

Variants

  • Teewurst Rügenwalder ArtNamed in the German food code; recipes vary by maker.
  • Grobe TeewurstCoarse-grained; at least 11 % connective-tissue-free meat protein.
  • RindswurstOnly lean beef and fat.

Safety

Teewurst is eaten raw with a pH around 5.3–5.5 and high water activity, so the main hurdles are nitrite and acidity. In a challenge test, STEC O26:H11 fell by only 0.5 log in 28 days in teewurst, far less than in salami. Lab work shows L. monocytogenes could not multiply at pH 6.0 and below with 200 mg/l sodium nitrite.

Hazards the sources name: Shiga toxin-producing Escherichia coli O26:H11 (fell only 0.5 log in 28 days in a challenge test); Listeria monocytogenes, Salmonella Typhimurium, E. coli O157:H7 (challenge tests); Yersinia pseudotuberculosis (survived 2-day ripening in a challenge test).

History and sources

Every number is labelled with how it is known. How this atlas is made

The sausage is tied to Rügenwalde in Pomerania (now Darłowo, Poland). The German food code lists "Teewurst, Rügenwalder Art" among spreadable raw sausages.
