Fig. 2.

Frequency of missed positive carcasses at meat inspection at varying sensitivity using the artificial digestion test. At larval abundance above 1000 Trichinella muscle larvae per 100 g of diaphragm (LP100G) (d, e), the frequency of missed positive carcasses decreased to zero at maximum relative test sensitivity (1.0). At lower infection levels per 100 g diaphragm (a, b, c), the frequency of missed positive carcasses decreased with increasing test sensitivity. However, due to a test sensitivity limit of 1 LPG (100 LP100G) of the artificial digestion test at meat inspection, not all positive carcasses will be detected.
