Nététou (Senegalese fermented néré)
Nététou · netetu · néré condiment
Nététou is a Senegalese condiment of fermented African locust bean cotyledons. Casamance accounts describe staged cooking, dehulling and 48–72 hours of fermentation; these are not validated household safety limits.
A Senegalese Parkia condiment
Nététou, also written netetu, is a fermented condiment made from the seeds of African locust bean, Parkia biglobosa. The seed cotyledons are cooked, dehulled, washed, recooked and fermented. Senegalese sources describe the product as a seasoning for meals and document it in Casamance production and Dakar markets.
Nététou belongs to a wider West African family of fermented Parkia seed condiments known by names including iru, dawadawa and soumbala. Shared ingredients do not make the local preparations interchangeable. This record covers the Senegalese account; it does not apply the separate Beninese Iru process with iku-iru or the other named regional methods.

Casamance production and trade
A 1996 account describes producer groups in Kagnarou, north of Bignona in Basse Casamance, and trade from Casamance to Dakar. It reports that the work was organized largely through women's groups and that seeds could be collected locally or brought from Guinea. A 2020 study of Kagnobon and Mangagoulack separately reports household seed fermentation into condiment. These are named places and study settings, not evidence that production is restricted to them.
One account places pod collection in April–June. The 1996 market-chain source describes a production campaign from December to June, reflecting that seeds may be processed after harvest and traded. The dates refer to different stages in the chain and should not be reduced to a single national harvest calendar.
Reported process, with unresolved variation
One Senegalese process account describes boiling the seeds for 12–24 hours, pounding to loosen the coats, washing the cotyledons, cooking them again for about three hours and fermenting them for 48–72 hours. It then reports salting and partial drying. A 1999 study record describes microbial-quality sampling at eight stages; its indexed abstract summary gives a 12-hour first boil and a 48-hour fermentation. These accounts overlap but do not establish one controlled household method.
The available material does not establish a reliable household starting mass, water ratio, salt quantity, fermentation temperature, dry-matter endpoint, yield or storage life. The 48–72-hour range describes reported practice. It is not a validated safety limit. The final product is reported in ball form in Senegal; other shapes described for Mali or northern Cameroon belong to those source contexts.
Food safety and open evidence
The 1999 study focuses on microbial quality and contamination across stages of traditional production. Its full text was not available in the sources inspected here, so this record does not claim specific organism counts or a validated critical-control plan. The process reports also do not establish household critical limits for cooking, fermentation, drying, or storage.
Do not infer safety from the strong aroma, colour, ammonia odour or visible changes associated with fermentation. A validated household safety schedule and storage guidance remain open research needs; the available process descriptions should be read as historical and technical observations, not as proof that a home batch is safe.
History
Nététou is documented as a Senegalese fermented néré condiment in a 1996 account of Casamance producer groups and trade, and in a 1999 process study. These sources document the practice at those dates; they do not establish when it began.

Unvalidated spontaneous fermentation and handling
A study of the traditional process specifically assessed microbial quality and contamination at multiple process stages, while the available summaries do not establish a validated household control schedule. Long cooking and a reported 48–72-hour fermentation are process descriptions, not proof of safety.
Hazard sourceThe reported times are descriptions of studied or documented practice, not validated critical limits. The sources reviewed do not establish household controls for temperature, pH, water activity, drying or storage.
Do not use smell, taste, colour, ammonia odour or visible fermentation as proof that a batch is safe.
A 1999 process study is available here through its bibliographic record and summary, not its full text; its detailed findings and any proposed critical control points remain unverified.
- Collect mature néré pods and separate the seeds. A Senegal account reports pod collection from April to June; a separate 1996 market-chain account describes a production campaign from December to June using stored or traded seed. These calendars describe different stages and local accounts.
- Boil the seeds in water to soften their tough coats. One process account gives 12–24 hours; an indexed 1999 study summary reports a 12-hour initial boil. These are reported process observations, not validated safety limits.
- Dehull the softened seeds by pounding, then wash and separate the cotyledons from loosened coats and any abrasive material. A Casamance account describes hand pounding with sand used as an abrasive; it reports this as laborious and followed by washing.
- Cook the cleaned cotyledons again. One account gives about three hours; exact household equipment, vessel geometry, fuel use and starting batch mass are not sufficiently established here.
- Drain and ferment the cooked cotyledons in sacks or other described containers. Reports give 48–72 hours in one account and 48 hours in the indexed 1999 process summary. This range records historical reports; it is not a safe endpoint.
- Salt and partially dry the fermented product as described in one account. Nététou is reported in Senegal in ball forms, and sources also describe partially dried or market forms. The amount of salt, drying endpoint and storage duration are not established.
