Update: I think I can, I think I can...

I finally got a reply from my letter to Seneca Foods. I'm not very satisfied with it; it seems there's some confusion regarding to whom it should be addressed--I sent my e-mail to consumer_affairs@senecafoods.com, so I'm a bit confused by the response:

Thank you for your comments on the vegetable cans. Seneca Foods makes their own cans. Your comments will be forwarded to the correct department. Seneca Foods sold the Juice Division in Dec. 1998.

Seneca Foods Consumer Affairs

Anyway...at least my voice was heard....

I'll try to keep everyone posted.
