Summary
Toxoplasma gondii is one of the most common parasitic
infections of humans and other warm-blooded animals.
In most adults it does not cause serious illness, but
severe disease may result from infection of fetuses and
immuno-compromised people. Consumption of raw or
undercooked meats has been consistently identified as
an important source of exposure to T. gondii. Several
studies indicate the potential failure to inactivate T. gon-
dii in the processes of cured meat products, referred to
as smallgoods in Australia.
This publication presents a qualitative risk-based assess-
ment of the processing of ready-to-eat smallgoods. The
raw meat ingredients are rated with respect to their likeli-
hood of containing T. gondii cysts and an adjustment is
made based on whether all the meat from a particular
source is frozen. Next the effectiveness of common
processing steps to inactivate T. gondii cysts are assessed,
including addition of spices, nitrates, nitrites and salt, use
of fermentation, smoking and heat treatment, and the
time and temperature during maturation. It is concluded
that processing steps which may be effective in the inacti-
vation of T. gondii cysts include freezing, heat treatment
and cooking, and the interaction between salt concentra-
tion, maturation time and temperature. The assessment is
the illustrated using a Microsoft Excel based software tool
which was developed to facilitate the easy assessment of
four hypothetical smallgoods products.
