Refreezing. Once food is thawed in the refrigerator, it is safe to refreeze it without cooking, although there may be a loss of quality due to the moisture lost through thawing. After cooking raw foods which were previously frozen, it is safe to freeze the cooked foods.o not refreeze any foods left outside the refrigerator longer than 2 hours; 1 hour in temperatures above 90 Â°F. If you purchase previously frozen meat, poultry or fish at a retail store, you can refreeze if it has been handled properly.

Basic concrete slab cost. I'll base my price on what my actual estimate would be to install a 6 thick concrete slab for one of my customers. Base cost for a 6 thick concrete slab -- $4.00 dollars per square foot --. Take the length of the concrete slab x the width of the slab to get the.total square footage. Multiply the total square footage by 4 (dollars) to get the total price. concrete slab is poured right on a gravel pad and the edges are formed with 2x4's, 2x6's, 2x8's etc. A concrete floor is poured inside a concrete foundation, ICF walls, cement block walls, I think you get the idea.
