Certain Transactions Disclosure [Text Block]	16. Certain Transactions A small percentage (less than 1% in fiscal 2014, 2013 and 2012) of vegetables supplied to the Company's New York packaging plants are grown by a director of Seneca Foods Corporation, which supplied the Company approximately $1.1 million, $1.2 million, and $0.8 million pursuant to a raw vegetable grower contract in fiscal 2014, 2013 and 2012, respectively. The Chairman of the Audit Committee reviewed the relationship and determined that the contract was negotiated at arm's length and on no more favorable terms than to other growers in the marketplace.
