Regulation of the Day 65: Weighing Animals

If you sell poultry or livestock, it’s a good idea to weigh them first. Makes it easier for buyer and seller to agree on a fair price.

For some reason, seven sections of the Code of Federal Regulations (see here, here, here, here, here, here, and here) deal with the use and maintenance of the scales used to weigh the animals, the people operating them, proper procedure, and finally, weighing the animals again.

Is this really a federal matter? If so, what isn’t?
