Abstract

Attieke is a traditional fermented cassava-based food widely consumed in West Africa, particularly in the Republic of Guinea, where it represents an important component of the daily diet. Its microbiological quality is strongly influenced by artisanal processing methods, post-fermentation handling practices, storage conditions, and marketing environments, which may affect product safety. This study aimed to evaluate the microbiological quality of attieke sold in the urban municipality of Macenta, Guinea. Sixteen samples were randomly collected from different retail outlets and analyzed using standard microbiological methods. The parameters investigated included total aerobic mesophilic flora, total and thermotolerant coliforms, Staphylococcus aureus, yeasts and molds, and Salmonella spp. The results showed total aerobic mesophilic counts ranging from 15 to 1,000 CFU/g. Total coliforms were detected in 62.5% of samples, while thermotolerant coliforms were present in 50%, indicating inadequate hygienic conditions during processing and distribution. Staphylococcus aureus and yeasts and molds were detected in 81.3% of samples, with maximum counts of 44 CFU/g and 310 CFU/g, respectively. Salmonella spp. was not detected in any sample (absence in 25 g). Overall, microbial loads were within acceptable limits for ready-to-eat foods. However, the presence of hygiene indicator microorganisms highlights the need to strengthen good hygiene practices throughout the production and distribution chain in order to improve food safety.

1. Introduction
Attieke is a traditional fermented cassava-based food produced from Manihot esculenta Crantz, originating from Côte d’Ivoire and widely consumed in West Africa, particularly in the Republic of Guinea. Appreciated for its high energy value, affordability, ease of preparation, and granular texture similar to couscous, attieke is an essential ready-to-eat food in the daily diet of many populations in both urban and rural areas .
Attieke production is based on a predominantly artisanal process involving several successive steps, including fermen-tation, pressing, granulation, and steaming . Fermentation plays a central role from both technological and sanitary perspectives, contributing to the reduction of cyanogenic compounds naturally present in cassava and to the improvement of the product’s organoleptic properties .
However, the artisanal nature of processing, combined with often poorly controlled handling, packaging, and marketing conditions, exposes attieke to risks of microbiological contamination, particularly during post-fermentation stages . Several studies conducted in West Africa have reported the presence of hygiene indicator microorganisms, such as total coliforms, reflecting inadequate hygienic conditions, and Staphylococcus aureus, generally associated with human-origin contamination. More rarely, major regulated pathogens such as Salmonella spp have also been detected in attieke sold on local markets . In this context, assessing the microbiological quality of ready-to-eat foods, especially those produced through artisanal value chains, is of critical importance in developing countries, where sanitary control and microbiological surveillance systems often remain limited.
In the Republic of Guinea, particularly in the urban municipality of Macenta, attieke is widely produced, marketed, and consumed in local markets. However, unlike other countries in the sub-region such as Côte d’Ivoire or Burkina Faso, scientific data on the microbiological quality of attieke in this locality are scarce or nonexistent. Therefore, the present study aims to evaluate the microbiological quality of attieke marketed in Macenta by determining the levels and prevalence of major hygiene indicator and pathogenic microorganisms, and by comparing the results with recommended microbiological criteria for ready-to-eat foods. This study seeks to provide baseline data to support improvements in hygienic practices, sanitary risk management, and food safety at the local level.
2. Materials and Methods
2.1. Study Area
The present study was conducted in the urban municipality of Macenta, located in the administrative region of Nzerekore in Forest Guinea (Figure 1). This area was selected due to its central role in the production, marketing, and distribution of attieke at the local level. Its economic and nutritional importance makes it a relevant setting for assessing the micro-biological quality of this widely consumed food product among local populations.

2.2. Sampling
Sixteen (16) attieke samples were collected from sixteen (16) vendors selected based on the high customer traffic at their selling points in the market of the urban municipality of Macenta in October 2025 (Figure 2). Each sample, weighing 1,000 g, was obtained from a different vendor, aseptically packaged, and transported in an insulated cooler to the laboratory of the National Quality Control Office (ONCQ) in Conakry for analysis.

2.3. Microbiological Analyses
Total aerobic mesophilic flora (TAMF) were enumerated by the plate count method following decimal dilutions and incubation at 30°C for 48 h . Total and thermotolerant coliforms were enumerated on Compass ECC agar after incubation at 37°C and 44°C for 24 h, respectively . Staphylococcus aureus was enumerated in accordance with ISO 6888-1: 2021 using Baird-Parker agar, with incubation at 37°C for 48 h . Yeasts and molds were enumerated according to the NF ISO 6611 standard using Sabouraud and potato dextrose agar (PDA) media . The detection of Salmonella spp, was performed in accordance with ISO 6579-1: 2017 .

2.4. Statistical Analysis
Data were analyzed using STATA software (version 15.1) with descriptive statistical methods. Inferential statistical analyses were also performed to compare microbial loads among samples. A one-way analysis of variance (ANOVA) was used to assess significant differences between groups, followed, where appropriate, by Tukey’s post hoc test for pairwise comparisons. A significance level of p < 0.05 was adopted. In addition, the obtained results were compared with the relevant sanitary standards in order to identify any potential non-compliance.
3. Results
The Figure 4 presents the distribution of microbial loads of the analyzed attieke samples according to six (6) microbio-logical parameters. The Figure highlights a marked inter-sample variability, reflecting the heterogeneity of processing, handling, and marketing conditions of attieke within the single market of the urban municipality of Macenta.
The observed microbiological loads showed inter-sample variability. Total aerobic mesophilic flora ranged from 10 to 10³ CFU/g, with maximum values remaining below the acceptable limits for ready-to-eat foods. Total and thermotoler-ant coliforms were detected at moderate levels. Staphylococcus aureus counts ranged between 10 and 10² CFU/g. Yeasts and molds reached levels of up to 10³ CFU/g in some samples. No Salmonella was detected in any of the analyzed samples.

4. Discussion
The total aerobic mesophilic flora counts observed in the present study were generally lower than those reported in previous studies. For example, a microbial load of 4.8 × 10⁶ CFU/g was reported in garba, a street food widely consumed in Côte d’Ivoire Anoman, A. T., et al., (2019) . Similarly, a microbial concentration of 1.7 × 10⁶ CFU/kg was found in a study investigating residual hydrocyanic acid content and the microbiological quality of attiéké in the Abidjan region Koffi, L., et al., (2009) . Furthermore, a study conducted in Burkina Faso on artisanal attieke produced in Dedougou at the local processing unit “Burkina Journalier” reported microbial loads ranging from 3.73 to 4.52 log CFU/g, which were also higher than those measured in the present study Dembele, R., et al., (2018) . In the same vein, higher total aerobic mesophilic flora counts (8.2 × 10⁷ CFU/g) were reported in a study on the characterization of the microflora of attieke during traditional small-scale preparation Coulin, P., et al., (2006) .
These differences may be attributed to variations in processing conditions, handling practices, storage methods, and production environments specific to each study area. Additionally, differences in the application of hygienic practices during post-fermentation stages may have contributed to the lower microbial loads observed in attieke samples analyzed in Macenta.
The results of the present study highlight total coliform loads that were generally lower than those reported in several similar studies conducted in West Africa. Thus, Kouassi, K. B., et al., (2025) , in their study on the quality characteristics of attieke produced in the lagoon areas of Côte d’Ivoire, did not detect any total coliforms in samples collected from different production sites, in contrast to the findings from Macenta, where a moderate presence of coliforms was observed in some samples. Conversely, Kouadio-Yapo C. G., et al., (2018) reported markedly higher contamination levels, with microbial loads reaching 8.6 × 10⁷ CFU/g in samples collected in Lobia, indicating a significantly higher degree of contamination than that measured in the present study. The total coliform colony counts observed in this study were lower than those reported by Flibert G., et al., (2021) , who investigated the lactic acid bacteria and yeasts involved in cassava fermentation for attieke production in Burkina Faso and their technological properties, reporting a microbial load of 0.98 log CFU/g. These discrepancies may be attributed to differences in processing conditions, handling practices, and storage methods specific to each production area.
The thermotolerant coliform counts observed in the present study were lower than those reported by Koffi, L., et al., (2009) , who highlighted an average concentration of 1.6 × 10³ CFU/g in their analysis of residual hydrocyanic acid levels and the microbiological quality of attieke produced in the Abidjan region. The thermotolerant coliform counts observed in this study were lower than those reported by Assanvo JB., et al., (2006) in their study on the microflora of traditional cassava starter used for attieke production in Dabou, Côte d’Ivoire, which were 8.0 × 10³ CFU/g. These differences may be explained by variations in production conditions, hygienic practices, as well as the analytical protocols employed.
The yeast and mold counts observed in the present study were markedly lower than those reported by Kouadio-Yapo C. G., et al., (2018) , who, in their investigation on the identification of yeast species present in attiéké marketed in Abidjan markets, recorded an average concentration of 1.01 × 10⁶ CFU/g. In an assessment of the microbiological quality of attiéké (steamed cassava) sold in Côte d’Ivoire, a microbial load of 2.7 × 10⁶ CFU/g was reported by Nazo Edith K-K et al. (2020) . These differences may be explained by variations in processing conditions, hygienic practices, storage methods, and marketing channels specific to the geographical areas studied.
The Staphylococcus aureus counts observed in the present study were lower than those reported by Alfred, K. K., et al., (2019) , who assessed the microbiological and chemical risks associated with commercial attieke produced in southern Côte d’Ivoire. In that study, microbial concentrations ranged from (1.8 ± 0.4) × 10² CFU/g in Jacqueville to (4.3 ± 1.8) × 10³ CFU/g in Abidjan. The Staphylococcus aureus load enumerated in the present study is comparable to that reported by Akmel, D. C., et al., (2017) , who also observed values below 10² CFU/g across all the zones or cities studied, in the context of the quantitative assessment of microbiological risk associated with the consumption of attieke in Côte d’Ivoire. These discrepancies may be attributed to regional variations in production, handling, and storage conditions, as well as differences in hygienic practices, which directly influence microbial loads and, consequently, the sanitary quality of the product.
The results regarding Salmonella spp in the present study are consistent with those reported by Alfred, K. K., et al., (2019) , who demonstrated the absence of Salmonella in all analyzed samples during their evaluation of microbiological and chemical risks associated with commercial attieke produced in southern Côte d’Ivoire. Similarly, Krabi Ekona, R., et al., (2015) , in their study on the production of attieke (fermented cassava couscous) in Abidjan, also reported the absence of Salmonella, regardless of the cassava variety used. These convergent findings suggest that, despite the artisanal nature of processing, certain production practices effectively contribute to limiting contamination by this pathogen.
5. Conclusions
The present study assessed the microbiological quality of attieke marketed in the urban municipality of Macenta, Republic of Guinea. Overall, the results indicate that the measured microbial loads were largely compliant with the recommended microbiological criteria for ready-to-eat foods, reflecting a generally satisfactory sanitary quality of the analyzed product. The absence of Salmonella in all samples constitutes a reassuring indicator from a food safety perspective. However, the detection of total and thermotolerant coliforms, as well as the relatively frequent presence of Staphylococcus aureus, highlights hygiene deficiencies that may occur during post-fermentation stages, particularly during handling, packaging, and marketing. In addition, yeast and mold counts, although characteristic of traditional fermented products, may contribute to product deterioration and reduced shelf life when present at high levels. These findings underscore the need to strengthen the implementation of good hygiene and manufacturing practices through-out the attieke production chain. Actions such as training of stakeholders, improvement of handling and selling conditions, and the establishment of regular microbiological monitoring could contribute to sustainably enhancing the sanitary quality of the product. Finally, further studies involving a larger number of samples and the evaluation of physicochemical parameters would help deepen the understanding of factors influencing the microbiological quality of attieke and better guide improvement strategies.
