Semidry sausages usually contain an important proportion of beef. Their shelf life is surprisingly good due to low water activity, accumulation of acids and smoke compounds, counteracting the effect of lactic acid bacteria on spoilage microorganisms, etc. A high level of hygiene and the ability to perform dexterously all operations in the manufacturing process are basic prerequisites for the good keeping quality of semidry sausages. Semidry sausages have improved stability if stored in the chiller, protected from humidity rather than at room temperature.
