applying a pre-rinse with wash water to the product prior to applying the short-term wash treatment solution; and

disposing of the wash water directly after applying the pre-rinse.

8. The method of claim 3 , wherein the short-term wash treatment solution provides at least one or more from a group consisting of antimicrobial properties, potentiating properties for antimicrobial action of the wash device and the wash treatment, and controlling properties for controlling lachrymator release from the product.

9. The method of claim 3 , wherein:

the acidulant is one selected from a group consisting of phosphoric acid, lactic acid, acetic acid, and bisulfide acid;

the acidulant is between 0.1% to 10% by weight of the short-term wash treatment solution;

the polyol is one selected from a group consisting of a glycerin and a propylene glycol; and

the polyol is from 0.1% to 10% by weight of the short-term wash treatment solution.

10. The method of claim 9 , wherein the wash treatment comprises:

free active chlorine from 2 to 40 ppm by weight of the wash treatment;

a compatible acidulant selected from a group consisting of phosphoric acid, citric acid, and lactic acid, wherein the compatible acidulant is from 10 to 1000 ppm by weight of the wash treatment; and

a polyol selected from a group consisting of a glycerin and a propylene glycol, wherein the polyol is from 2 to 500 ppm by weight of the wash treatment.

11. The method of claim 3 , further comprising determining at least one of product overload, inadequate chlorine in a flotation tank, and incomplete pH control with respect to the short-term wash treatment solution or the short-term wash device.

12. The method of claim 3 , wherein the short-term wash treatment solution provides a supplemental wash lethality of greater than 1 log against microbes found on the product as compared to the lethality of the wash treatment in the wash device alone.

13. The method of claim 3 , wherein:

the short-term wash device comprises at least one from a group consisting of a rotating drum short-term wash device, an air column short-term wash device, a slicer/dicer short-term wash device, a spray curtain, a shaker, and a timing belt; and

applying the short-term wash treatment solution comprises spraying, with a spray device integrated with the at least one from the group, the short-term wash treatment solution on the product.

14. The method of claim 3 , wherein applying the short-term wash treatment solution to the product comprises:

submersing the product into the short-term wash treatment solution; and

sifting the product out of the short-term wash treatment solution.

15. The method of claim 3 , wherein applying the short-term wash treatment solution comprises spraying the short-term wash treatment solution on the product.

16. The method of claim 3 , wherein the wash treatment comprises:

a compatible acidulant selected from a group consisting of phosphoric acid, citric acid, and lactic acid with the compatible acidulant from 10 to 1000 ppm by weight of the wash treatment;

a polyol selected from a group consisting of glycerin and propylene glycol with the polyol from 1 to 500 ppm by weight of the wash treatment;
