The investigative approach to data collection was adopted in
combination with desk research (secondary data collection) and
other strategies. The main abattoir in Tamale was selected for this
study. Data on the number of ruminants (cattle, goats and sheep)
slaughtered daily was collected (through participant observation)
between April and June, 2013. This was backed with data obtained
from records on abattoir operations. Additional information was
collected through questionnaire administered to butchers and
interviews with key informants (veterinary experts and meat
inspectors) using interview schedule. Waste materials generated
from abattoir operations was estimated based on calculations by
Aniebo et al. (2009) (Table 1). The computations were done using
average data on body weight for the respective ruminants and
carcass weight per 1,000 kg.
