But a home garden wouldn't be: a "food establishment" that stores, holds, or transports food products prior to delivery for retail sale.
You need to look at how the bill defines "food establishment"
(13) FOOD ESTABLISHMENT-
(A) IN GENERAL- The term food establishment' means a slaughterhouse (except those regulated under the Federal Meat Inspection Act or the Poultry Products Inspection Act), factory, warehouse, or facility owned or operated by a person located in any State that processes food or a facility that holds, stores, or transports food or food ingredients.
(B) EXCLUSIONS- For the purposes of registration, the term food establishment' does not include a food production facility as defined in paragraph (14), restaurant, other retail food establishment, nonprofit food establishment in which food is prepared for or served directly to the consumer, or fishing vessel (other than a fishing vessel engaged in processing, as that term is defined in section 123.3 of title 21, Code of Federal Regulations).
Paragraph (14) FOOD PRODUCTION FACILITY- The term food production facility' means any farm, ranch, orchard, vineyard, aquaculture facility, or confined animal-feeding operation.
Putting them together it reads like this:
(B) EXCLUSIONS- For the purposes of registration, the term food establishment' does not include any farm, ranch, orchard, vineyard, aquaculture facility, or confined animal-feeding operation, restaurant, other retail food establishment, nonprofit food establishment in which food is prepared for or served directly to the consumer, or fishing vessel (other than a fishing vessel engaged in processing, as that term is defined in section 123.3 of title 21, Code of Federal Regulations).
IMHO, it would be quite a stretch to come after home gardeners or farmer's market vendors under the definitions and exclusions. It just seems completely contrary given the language of the bill.
