Trimming, Hot Water, & Organic Acids

Summary:

This is a report that was created to give recommendations on a variety of intervention processes used in beef carcass slaughter. The authors also listed a variety of references for the intervention processes and the reduction in microbial growth in table format. The purpose of this report was to give general information on microbiological growth and to offer assistance to plants looking to create or reassess their HACCP plans.

Dry Aging, Hot Water Spray, Acetic Acid, & Fresh Bloom™

Summary:

The following peer-reviewed research paper supports a variety of beef slaughter intervention treatments commonly used by small plants. Processors who use one of the following beef slaughter intervention treatments:  dry-aging, low-pressure hot-water spray, high-pressure hot water spray, 2.5% acetic acid spray or Fresh Bloom™ may be able to use this paper as Supporting Documentation. The Critical Limit summaries below highlight aspects of the published work.

Spray Treatments

Summary:

Pennsylvania State University, along with Washington State University and Texas Tech University, has developed a video for small plants that describes antimicrobial spray treatments (water and acid washes) that many small plants may find effective.

Soak Treatments for Chickens Slaughtered in Mobile Slaughter Operations

Summary:

The following peer-reviewed research paper supports the use of a 3-minute soak in an ambient-temperature solution of 2% lactic acid to reduce incidence and levels of Salmonella in chickens slaughtered in mobile slaughter operations.  Each carcass was immersed in 15.1 liters of the lactic acid solution for 3 minutes.  The acid solution was changed at least once per 60 birds, when a high level of feathers, blood, or other debris had accumulated. Processors who wish to use this treatment may be able to use this paper as Supporting Documentation.
