Cereal-based dry foods such as pasta, flour, cakes, rice and others
may be subject to insect infestations. The attack to packaged foods
can occur during the production phases or in the following steps of
the distribution, such as transportation and storage in warehouses
or in retail stores. In any case, consumers frequently blame the manufacturers
for any occurring insect contamination, independently
from their real involvement, and the consequences on the image of
the company can be severe (Hou, Field, & Taylor, 2004).
