Don't be fooled when buying poultry, meat or seafood. Arizona law requires these items be sold by weight unless they are sold in a standard package.   What's the difference?   A standard package is part of a lot, shipment or delivery of packages of the same commodity with identical net contents declarations. If sold by count, each item must be of equal weight. A random package is a package that is one of a lot, shipment or delivery of packages that do not have a set pattern of weights.   To check the weight of the products you're buying and to make sure you're not paying for the packaging, follow these simple guidelines:   Step 1) Take the package to a deli or meat scale. If the scale has a "Not Legal For Trade" notice on it, it is an estimating scale and may not record the product weight accurately.   Step 2) Place the package on the scale. Make sure the scale weight is more than the net weight shown on the label. If the package weighs the same or less than the net weight, YOU ARE PAYING TOO MUCH and you should have the store reweigh the contents. Note: If you want to sound really official, tell them to take out the tare weight (that's the packaging material weight.   You should never pay for packaging).   To learn more about how the Department conducts packaging inspections, see NIST Handbook 133.   To learn more about meat, seafood and poultry legal method of sale requirements see NIST Handbook 130 1.5.
