If, on the date of the notice issued pursuant to Section 62582, a producer has a contract with the handler which is on file with the secretary, and that producer has received payment from a handler whose milk purchases have been declared ineligible, shipments by that producer which occur more than five days from the date of the notice of ineligibility issued by the secretary will not be considered in determining any claim the producer may make against the fund, unless the secretary reestablishes eligibility for future shipments to be covered by the fund.
