5. Proximate analysis 6. Presence of contaminates


If positive microbial tests indicate the presence of pathogens, the following steps should be taken (1):


1. Retest (use outside, reliable commercial labs) 2. Identify/isolate suspect product (include previous and subsequent lots)


3. Report as required to regulatory agency (within 24 hours) 4. Take appropriate action to protect public health (stop release – initiate recall)


5. Investigate cause/source of contamination 6. Dispose of product 7. Update feed safety programs


a) Review GMP and HACCP programs b) Re-evaluate current sampling/testing protocols c) Label all products with lot/date codes d) Participate in educational programs and regulatory processes


In summary, the way forward in pet food safety includes the following steps:


1. Supplier quality assurance programs 2. Plant and equipment design 3. Identify hazards and then establish and validate Critical Control


Points in the process 4. Implement Food/Feed Safety Management Systems (GMP’s and HACCP)


5. Finished product testing (traceability and rapid methods) References

INNOVATION DISTINGUISHES BETWEEN A LEADER AND A FOLLOWER. —Steve Jobs


Are you ready to run with the big dogs?


New products. New specifications. Maybe a new niche - or even just a new marketing direction. Any of these scenarios can create a serious need for new petfood processing initiatives. As the recognized leader in extrusion, Wenger is addressing these and other challenges with ground-breaking approaches for petfood production. Consider these recent Wenger innovations: the Thermal Twin Screw Extruder, with four times more steam injection, permits high percentages of fresh meat and high moisture ingredients, optimizes energy use; and the High Intensity Preconditioner (HIP), with adjustable mixing intensity, addresses recipe challenges - especially those with varying content of fats, starch and fiber. And the list goes on.
