African fermented foods, drinks and preservation
From sour breads and milk to savoury seeds, cassava staples and living beers, African fermentation follows the crop, the community and the work of transformation.
Mindeshi
Mendeshi
Mindeshi (also Mendeshi) is a Sudanese fermented paste made from small fish, pounded and sometimes dried. Sources disagree about how it relates to Terkin and do not establish one validated process or safety control.
A small-fish paste from Sudan
Mindeshi, also spelled Mendeshi, is a fermented fish paste associated with Sudan. Dirar describes small fish pounded into a paste, fermented and sometimes dried later. His account separates Mindeshi from fessiekh, whole salted fish; kejeik, split or dried fish; and terkin/meluha, a fermented fish sauce or paste. Sources vary on the relationship between Mindeshi and Terkin, so the names should not be treated as interchangeable.
A 1992 FAO survey associates the preparation with south-western Sudan. A later study collected a Mendeshi sample in the Khartoum area, but sampling there does not show that the product originated there or is made only in that area.
Partial and overlapping process accounts
Dirar's short description gives pounding, fermentation and optional later drying, but no complete batch or control schedule. FAO gives a longer procedure under a combined Terkeen/Mindeshi heading: fish is washed and salted in layers in an earthenware pot or barrel; pepper or other spices may be used; the vessel is then warmed in the sun or near a fireplace and stirred until the fish forms a paste. Because the account groups two products, it is evidence for a reported Sudanese process family, not proof that every Mindeshi uses that exact method.
The sources do not establish whether the fish are gutted, the fish-to-salt amount for Mindeshi, time and temperature controls, acidity, water activity, the role of drying or a safe storage method. The recorded durations and amounts in overlapping accounts are observations, not safety limits.
Fish identity and safety evidence
Dirar describes Sudanese fish ferments as made from freshwater Nile fish. The 2020 study reports Mendeshi from Synodontis spp. and cites Dirar for Mormyrus spp. as another possible fish; FAO's grouped Terkeen/Mindeshi list gives tilapia, Nile perch and Alestes spp. These reports differ in scope and should not be collapsed into a single definitive species list.
The 2022 study sampled Mendeshi among 44 Sudanese fermented foods and reports harmful bacteria and fungi across the sampled foods, without naming Mendeshi-specific organisms or prevalence. FDA guidance identifies hazards in preserved fish including C. botulinum toxin formation and inadequate drying. FDA's examples of illness from uneviscerated fish are general hazard context, not evidence of a Mindeshi outbreak. No validated process controls are supplied by the Mindeshi sources.
History
Dirar's 1992 chapter distinguishes Mindeshi from other Sudanese fermented fish products. A 2022 study includes a Mendeshi sample but does not establish a first date or origin.

Risks and precautions · High risk
Clostridium botulinum toxin
Mindeshi sources do not establish evisceration status, salt concentration, pH, water activity, time-temperature control or drying endpoint. FDA identifies botulism risk in improperly controlled preserved fish and warns that toxin may occur without outward spoilage; its uneviscerated-fish outbreak examples are not evidence of Mindeshi-specific illness.
Hazard sourceOther foodborne bacteria and fungi
A 2022 study of 44 Sudanese fermented foods, including sampled Mendeshi, reports finding harmful bacteria and fungi among the foods due to preparatory methods. Its abstract does not identify Mindeshi-specific organisms or establish prevalence or safety.
Hazard sourceFish allergen
Mindeshi is made from fish; fish is a major food allergen requiring clear identification for people with fish allergy.
Hazard sourceThe published accounts do not establish a validated home process or safe control limits for Mindeshi.
The fish's evisceration status and the fermentation's salt, pH, water-activity and time-temperature controls are not established.
FDA states that botulinum toxin may be present without visible spoilage. Smell, taste, bubbling or appearance cannot establish safety.
Do not use reported durations, salt proportions or sun/fireplace warming as safety limits. No validated drying endpoint or storage limit is available.
- This source comparison is not a validated home-preservation recipe. Mindeshi is distinct from fessiekh, the salted fermented whole-fish preparation, kejeik, the split or dried fish, and Terkin/meluha, described as sauce or paste. The sources disagree about whether or how Mindeshi relates to Terkin.
- Dirar describes Mindeshi as small fish pounded into a paste, fermented and sometimes dried later. He describes Sudanese fish ferments as products of freshwater Nile fish, but does not provide a complete Mindeshi batch method, ingredient ratios or controlled schedule.
- An FAO technical survey gives a more detailed Sudanese procedure under the combined heading “Terkeen/Mindeshi”: fish is washed and salted in layers in an earthenware pot or barrel; pepper or other spices may be added. It reports a pickling/fermentation stage followed by warming the vessel in sun or near a fireplace and daily stirring until fish muscle and bones form a paste. Because the source combines two preparations, this sequence cannot be assigned to every Mindeshi version.
- The same FAO account lists tilapia, Nile perch and Alestes spp. for the combined Terkeen/Mindeshi group. A later Sudanese study sampled Mendeshi made from Synodontis spp. at Khartoum-area fish markets; its introduction also reports Dirar's note that Mormyrus spp. may be used. Keep these as distinct, source-specific species reports rather than a universal ingredient list.
- Sources describe paste that may later be dried, but do not establish whether drying is routine, the fish are gutted, the salt level, fermentation conditions, a safe drying endpoint or a storage method. Do not combine source-specific details into an assumed safe process.
