Abstract
The present invention provides compositions and methods for sanitization or sterilization of, or reduction or elimination of microbes from, PFR material, in particular material for use as an animal bedding. In another aspect, the invention provides sanitized or sterilized material, and especially animal bedding material, prepared using the described compositions and methods.
Claims21
A bedding material composition, produced by the process comprising:
- combining a PFR material with a germinant and water to produce a PFR material mix, wherein said germinant is effective to promote germination of bacterial endospores;
- exposing said PFR material mix to a heat-shock comprising 65° to 90° C. for 10 to 30 minutes;
- incubating the PFR material mix at between about 35° and about 45° C. for 20 to 35 minutes;
- and
- heating the PFR material mix at between 115 and 177° C. for approximately 15 to 40 minutes;
- wherein the PFR material mix contains 10 or less CFU/g of viable microbes in the PFR material;
- and
- wherein said PFR material mix contains less than 20% moisture content after said heating step.

A PFR material produced by the method comprising:
- wetting the PFR material with water and a germinant, wherein PFR material is completely coated with said water and germinant and wherein said germinant is effective to promote germination of bacterial endospores;
- exposing said PFR material to a heat-shock comprising 65° to 90° C. for 10 to 30 minutes;
- incubating the PFR material at between about 35° and about 45° C. for 20 to 35 minutes;
- and
- heating the PFR material at least between 115 and 177° C. for approximately 15 to 40 minutes;
- wherein said process is performed in one day or less;
- and
- wherein the PFR material contains 10 or less CFU/g of viable microbes in the PFR material;
- and
- wherein said PFR material contains less than 20% moisture content after said heating.
