Food
safety is a critical component of every phase of BPI's operations,
beginning with procurement of raw materials, through customer
education on the best methods for incorporating BPI products
into their own production to ensure maximum benefit from
BPI technologies.
Raw materials are purchased only from suppliers
who have validated CCP's in place for pathogen elimination
or reduction. Those raw materials are transported to BPI
and stored in a manner to minimize any potential bacterial
growth. Those raw materials are then subjected to up to
four processing steps, each of which independently produces
microbiological reductions. When all of those processing
steps are combined, as with the production of BPI®
Boneless Lean Beef Trimmings (blocks), the microbiological
reductions are truly impressive.
In two independent process validation studies
conducted by Iowa State University and National Food Laboratory,
Inc., the BPI process1 eliminated
all E.coliO157:H7 in the inoculated product, as well
as producing significant reductions of Salmonella and Listeria
monocytogenes. The Iowa State study has been accepted for
publication in the Journal of Food Protection. The
chart below summarizes the resutls of those two studies:

from each processing step.
Not only is the quality of BPI's product ensured,
but BPI customers have reported significant microbiological
improvements reductions in bacteria in their
finished products resulting from the use/blending of BPI®
Boneless Lean Beef Trimmings. In inoculated product studies,
blending BPI® Boneless Lean
Beef Trimmings at a 15% blend rate with inoculated ground
beef resulted in E.coli O157:H7 reductions of nearly
.25 Log10. This reduction exceeds the most probable
number of organisms associated with the large3
notable outbreak in 1992/93 in the western USA at quick
service restaurant chain. As noted in the Iowa State study,
"the reduction in populations of pathogenic bacteria
reported in this study would provide a significant margin
of safety."

pH enhancement, freeze/stressing, block compression, and
customer frozen block grinding (1/4 inch preferred).

reduction potential for E.coli O157:H7 was > 8.50
log.
