A decontamination tank for treating and reducing microbial contamination of a food product, the decontamination tank comprising:

• a first chamber for holding a first antimicrobial bearing liquid for reducing a microbial contamination on a surface of the food product;
• a second chamber for holding a second antimicrobial bearing liquid of different content than the first antimicrobial bearing liquid in the first chamber, for further reducing the microbial contamination on the surface of the food product;
• a first unloader configured to remove the food product from the first antimicrobial bearing liquid in the first chamber and to deposit the food product toward the second chamber;
• and
• a second unloader configured to remove the food product from the second antimicrobial bearing liquid in the second chamber,
• wherein the first chamber and the second chamber are separated from each other by at least a chamber wall extending to a bottom of the tank and that does not allow for the first antimicrobial bearing liquid or the second antimicrobial bearing liquid to intermix through the chamber wall.
