Disclosed are packaging systems and methods useful in extending the storage-life of foodstuff such as fresh fish. The packaging systems and methods can be used to transport or store the foodstuff for an extended period of time. The packaging systems preferably use a fuel cell to maintain a reduced oxygen level in the environment surrounding the foodstuff.

1. A sealed tote useful during transporting and/or storing of oxidatively-degradable foodstuffs which comprises: a) a tote comprising a flexible, collapsible or expandable material which does not puncture when collapsing or expanding, wherein the material has an oxygen transmission rate of less than 10 cubic centimeters/100 square inch/24 hours/atm, and wherein the tote comprises a sealable opening; andb) a fuel cell comprising an anode and a cathode which is capable of converting hydrogen and oxygen into water wherein the anode of the fuel cell is in communication with a hydrogen source and wherein the fuel cell is in gaseous communication with the tote. 2. The tote of claim 1, wherein the material is capable of maintaining its structural integrity up to a pressure differential between an outside pressure and an inside pressure of up to about 0.5 atm. 3. The tote of claim 1, wherein the fuel cell is maintained internal to the tote. 4. The tote of claim 1, wherein the fuel cell is maintained external to the tote. 5. The tote of claim 1 further comprising a carbon dioxide remover in communication with the fuel cell anode. 6. The tote of claim 5, wherein the carbon dioxide remover comprises hydrated lime. 7. The tote of claim 6, wherein the initial period of time is between about 0.5 and 50 hours. 8. The tote of claim 1, wherein the fuel cell is disconnected with the tote after an initial period of time that is sufficient to allow a natural minimization or cessation of gaseous exchange. 9. The tote of claim 1, wherein the fuel cell is disconnected from the tote when the oxygen level reaches and is maintained below a predetermined level. 10. The tote of claim 9, wherein the predetermined level of oxygen is below 5% oxygen v/v. 11. The tote of claim 9, wherein the predetermined level of oxygen is below 1% oxygen v/v. 12. A packaging module useful in transporting and/or storing of oxidatively-degradable foodstuffs which comprises: a) a sealed tote comprising a flexible, collapsible or expandable material which does not puncture when collapsing or expanding, wherein the material has an oxygen transmission rate of less than 10 cubic centimeters/100 square inch/24 hours/atm, and wherein the tote comprises a sealable opening;b) an oxidatively-degradable foodstuff;c) a fuel cell comprising a cathode and an anode which is capable of converting hydrogen and oxygen into water, wherein the anode of the fuel cell is in communication with a hydrogen source and wherein the fuel cell is in gaseous communication with the tote. 13. The packaging module of claim 12 wherein the fuel cell is maintained internal to the tote. 14. The packaging module of claim 12, wherein the fuel cell is maintained external to the tote. 15. The packaging module of claim 12, wherein the fuel cell is disconnected with the tote after an initial period of time that is sufficient to allow a natural minimization or cessation of gaseous exchange. 16. The packaging module of claim 15, wherein the initial period of time is between about 0.5 and 50 hours. 17. The packaging module of claim 12, wherein the fuel cell is disconnected from the tote when the oxygen level reaches and is maintained below a predetermined level. 18. The packaging module of claim 17, wherein the predetermined level of oxygen is below 5% oxygen v/v. 19. The packaging module of claim 17, wherein the predetermined level of oxygen is below 1% oxygen v/v.
