Project description: Nothing worse than a listeria outbreak at a food processing plant. This is a concern for everyone in the industry! J BAR B FOODS is an industry leader in preventing them. One of the challenges they face at their sausage plants in Texas is condensation between rooms and chiller rooms. The condensation is a hotbed for listeria and other bacteria growth. The seams in the insulated metal panels and the porosity of block wall are breading grounds if not treated properly.
