You mean you couldn't care less?

Exactly.
I travel with a dog, and always have a quantity of kibble-type dog food with me that, being a meat product, I always declare at the kiosk. The agent at the customs exit sends me over to Agriculture where they deal with it and then send me on my way (chances that the kibble gets confiscated are slim, btw. In 17 entries , it got taken exactly once). I was never subjected to secondary /had my bags searched/asked about other things than the dog food.
The agents at the agricultural inspection are also CBP. At least they wear CBP uniforms.

Funny Story about Dog Treats and the Agriculture Beagle.

My Wife and I brought a long a few doggie treats that our dog loves to give her Parents two dogs while we were staying at their place. We thought that we used them all while over there and upon arrival back in the USA, the Beagle hit on our bag and sat down.

My Wife started to laugh and she said to the Agent I think I know what he hit on and the Agent said, Oh you do?". My Wife opened the bag and took out the doggie treats and the Beagle was getting very very excited, the Agent smiled and said that was his/her (cannot remember the Gender of the Dog) favorite treat. My Wife offered the Agent the few remainder treats in case she wanted to give the Beagle them later when he/she was off duty. The Agent said that she cannot accept them, but that not too worry about the doggie treats and wished us a nice day, but the Beagle was not done just yet. He/She really wanted a treat and kept looking at the treats licking his/her lip and then looking at his/her handler.

Was a really cute and funny experience, but we were lucky to have a cool Agent and I guess a hungry dog, had we had a militant Agent might have gone differently.

Interesting fact re food. My son used a kiosk and in his question he was asked re specific foods like meat and in my question it was meat and etc, but inside that question there was also a word "food". So I did declare my candies just in case and be didn't declare his.

Attempt at departure declaration and guidance on GE
 

I went to Customs at SFO today to see if it was possible to make a departure declaration for prescription meds. I'm departing tomorrow in the early AM for a connection to HEL via JFK. The old Customs Office open to the landside of SFO next to the escalators between Terminal 3 and the International terminal is gone. They do all carnets and declarations inside the customs Hall (I don't know where you go for GE). I went to one of the private security guards standing at the doors outside customs, and One of them escorted me to one of the agents at the baggage inspection desk in the customs hall. They had never heard of declaring prescription meds prior to departure, had never done it, and had no procedure for it. The senior customs officer came over and said the same thing. I showed them the printout from the DEA of 21 CFR 1301.26. They didn't know anything about it. I asked if I could get a form 4457. They said no, because my meds don't have serial numbers. I asked if they could write prescription numbers on it. They said, "Well what if you empty them out and put other pills in?" I pointed out that if I try to come in with more pills than are on the label, they'd have a point, but the 4457 would at least show that I had left with them, and wasn't net importing meds. Everybody was very pleasant, but the consensus was that if you're not bringing in controlled-substance meds purchased overseas, and the meds you havem have the labels from your U.S. pharmacy, you're OK. They weren't even vaguely interested in the non-controlled substance prescription meds. Everyone was very pleasant about it.

I asked about coming back in with Global Entry. I was told I could go to the kiosk on re-entry, and just declare my meds to either the agent in the baggage hall, or the secondary screener. No need to get in the crew or regular line. It would be OK *provided that* I have my meds on original containers with legible labels and/or a written prescription from the doctor. Direct quote: "We're not going to penalize you for that."

YMMV.

Thanks for checking on that!

I was picking my Wife up at DFW, arrived early, so decided to speak with CBP and find out about declaring USA prescribed meds and if they had any idea of the procedure.

The two people at CBP I spoke with were both very nice and wanting to be helpful, one even commented that he was impressed a citizen was really trying to do the right thing to the T.

However, just like the person a few comments up from mine, essentially they had no idea of any process and furthermore said that nobody would be penalized for USA prescribed and fulfilled meds, nor non-scheduled meds prescribed and fulfilled overseas.

I asked what I should do if I did have medication with me, they both said declare it to the nearest CBP Officer in the Customs Halls or any Secondary Inspection Area, but there was no need to wait in line at Immigration and either way Medication legally prescribed in its original bottle with the prescription on it would never be an issue, in fact one of the Officers said to me he had a man just the other day who had samples from his Doctor along with a prescription and that was more than enough to prove that the man was supposed to have the meds.

I asked about Dexilant (Dexlansoprazole) a non-scheduled, non-narcotic PPI I am prescribed for heart burn visa vie Global Entry and the Supervisor said look at it this way, that he was unfamiliar with Dexilant but that unless I had narcotics than I really should not worry and if I did have narcotics just make sure that are from the USA, that they are in their original bottle with a prescription label and worse comes to worse I might have to wait while they check on the prescription, but that 9/10 as long as things check visually it really wouldn't be a problem.

Take it with a grain of salt, in my experience the rules are the rules depending on who you speak with, not simply that the rules are the rules.

I call the syndrome the "rule de jour." It is on the "menu" of every customs service in the world.
