Summary
Introduction
Meat processing is an important industry in
• Amounts
and types of offal
• Geographic
distribution of offal
• Seasonal
trends of production
• Current
methods of offal disposal
No historical data is available, as a survey of this type has never been
attempted in
Materials and Methods
A list of all state-and federally-inspected slaughter plants was
obtained from the State Meat Inspection Program of the North Dakota Department
of Agriculture. The project consisted of physically visiting each plant and
completing an offal production survey.
In 2004,
The one-page survey, which was completed on site with the processors,
included the following main
categories:
• Slaughter
data on cattle, hogs, deer and other animals
• Current
offal disposal methods
• Current
storage methods
• Frequency
of offal pickup and length of time offal is on site
• Current
cost of offal disposal
• Current
method of hide disposal
All 125 contacts completed the survey. Information was collected for
this report, as well as additional data to be used in future cost analysis
work.
Results
This report does not provide data from the major hog processor in the
state (Cloverdale Foods Inc.), nor does it provide data from the major bison
processor in the state (North American Bison Cooperative). These firms were
surveyed, but data from those surveys will not be disclosed to protect
confidentiality. Table 1 shows pounds per species, with the number of head
listed under pounds.

The southeast region of the state leads in the production of offal,
followed by the southwest, northwest and northeast (Table 2). The southern part
of the state produces more offal – 8.49 million pounds vs. 6.46 million pounds,
or 57% vs. 43%, of the total offal produced. However, if the state is divided
into east and west, the difference in offal production is quite small (7.68
million pounds in the west versus 7.26 million pounds in the east, or 51% vs.
49%).

The balance of the renderable offal is collected and processed in
When the major hog and bison processors are removed from the data set,
only 56% of the offal that the remaining 115 plants produce is rendered and 44%
is deposited in municipal and private landfills (Table 3). This totals 7.24
million pounds annually.
