TABLE 5.
The table summary of microbiological characterization of dried meat and meat products from various processing conditions, storage, packaging, and localities.
Dried meat/Meat products | Tested microorganisms | Conditions | Finding | References |
Beef, kudu, and springbok Biltong, dried, cured meat | L. monocytogenes, S. aureus, and S. pasteuri. | - Dry biltong’ (moisture content: 21.5–25.3 g/100 g; aw: 0.65–0.68) - “Moist biltong” (moisture content: 35.1–42.8 g/100 g; aw: 0.85–0.89) |
Distinct low TPC, high level of LAB and D-lactic acid was observed in “dry biltong” as compared to “moist biltong” group. Only S. aureus was periodically detected (2.6 log cfu/g), while L. monocytogenes and Salmonella were not detected. |

Tinko dried meat | Bacteria: S. aureus, Micrococcus luteus, Neisseria sp., and Acinetobacter sp. Fungi: Aspergillus niger, Penicillium sp., Rhizopus sp., and Aspergillus flavus |
Storage (rainy season) Cupboard Refrigerator |
Almost all except for Neisseria sp. bacterial isolates showed potentially resistance to antibiotics used. Increased bacterial counts were observed in the cupboard-stored (2.5 × 107–3.3 × 107 cfu/ml) samples as compared to refrigerated-stored (2.0 × 107–1.4 × 107 cfu/ml). |

Spanish cured meat | Mesophilic aerobic bacteria and psychrotrophic bacteria Enterobacteriaceae, S. aureus Salmonella spp., and L. monocytogenes |
Commercial packaging of variety cured meat products | Non-significant detection of Enterobacteriaceae was observed, while Salmonella spp. and L. monocytogenes were non-detected before enrichment S. aureus was detected in all samples (range 3.91–4.57 log cfu/g) in considerably safe level for food safety quality |
(91) |
Kitoza meat | Lactic acid bacteria and coagulase-negative staphylococci L. monocytogenes, S. aureus |
Different local manufacturer for sun-dried and/or smoked Kitoza | No Salmonella spp. were detected, on 1 sample contaminated with L. monocytogenes. B. cereus and C. perfringens under the detection threshold (2 and 1 log cfu/g, respectively). S. aureus has been observed to be significantly different for dried and smoke kitoza (P ≤ 0.001); S. aureus counts in dried kitoza (3.4 ± 1.0 log cfu/g) and smoked kitoza (2.3 ± 0.7 log cfu/g). |

El-Guedid dried meat | LAB and coagulase negative staphylococci L. mesenteroides, L. sakei, and S. saprophyticus S. aureus |
Raw meat from different origins and downstream processes (365 days storage) |
Enterobacteria counts were observed about 2.0 ± 1.0 log cfu/g throughout the storage. Listeria, Salmonella, and anaerobic sulfite-reducing bacteria (SRA) were not detected in this study. S. aureus was only detected in few samples and became below the detection threshold after (<10 log cfu/g). Yeasts and molds contaminated all samples of sliced fresh meat at average level of 3.0 ± 0.7 log cfu/g and across the storage period, it became under the detection threshold. |
