I have had animal shows all over the country...
I have a USDA Exib. B Licence..
Most USDA inspections do NOT allow any food to be kept in a rubber or plastic cont. They must be in an allum. trash can/or type of, either in the bag or not, and a tight fitting cover so that no rodents can get into it.
Plastic water bowls or rubber were not allowed because bacteria can easily grow in the "scratches" of the bowls, only metal, and must be disinfected reg.
For those who don't know... and yes, I thought when I first started training, doing animal shows...that the USDA was involved. Yes, they do the investigations and evaluations for animal shows all over the country as well as the "beef"...lol.
You would be amazed at the acutal animals they are "regulated" to do evals....hopefully soon, they will be able to do more.
No worries for me, my shows always got a great score! But, I just wanted to share the above.
