wheres the FDA

thousand of co2 containers are refilled and reshipped out to retailers. How many households are they in, how many diseases are on these containers? HIV, hepatitis, meningitis, flu, germs. the containers are not cleaned before they arrive at a retailer. How many hands have touched that container before you? what can you contract from touching it? did you ever think of that? where is the FDA for this? If the co2 is supposed to be food grade what controls are out there for sterile containers of that? what can you catch, who touched it last , how many touched it before you, where did it come from, if you buy a bottle of soda , once it is used you throw it out, limited germs, when you buy co2 it could have been in 100 homes before you, it could have been touched by a thousand people, and yet was it ever cleaned or sterilized externally ? NOPE. did you ever? will you buy this now? how are you effecting your household? yourself,your spouse, your children?
