Résumé

Channel catfish were inoculated with 3 to 4 log spores/gramme of a mixed pool of four strains of C. botulinum type E and were packaged with an oxygen-permeable overwrap, in an oxygen-barrier bag with a modified atmosphere of CO2-N2(80:20) or in a master bag with the same modified atmosphere. Packaged fish were stored at either 4 deg C and sampled at intervals over 12 days. An additional master bag treatment in which overwrap-packaged catfish was stored first at 4 deg C, then removed from the master bags and stored at 10 deg C, was sampled at intervals over 18 days. Toxin production was evaluated using the mouse bioassay. Aerobic psychrotrophic and anaerobic populations were enumerated, and product spoilage characteristics were noted. Results are given.
