A mathematical model was developed to characterize the interaction of fruit O_{2} uptake, steady-state O_{2} partial pressures in modified-atmosphere (MA) packages ([O_{2}]_{pkg}), and film permeability to O_{2} (Po
_{2}) from previously published data for highbush blueberry *(Vaccinium corymbosum* L. `Bluecrop') fruit held between 0 and 25C. O_{2} uptake in nonlimiting O_{2} (Ro

^{max,T}) and the [O_{2}]_{pkg} at which O_{2} uptake was half-maximal (K_{½}
^{T}) were both exponentially related to temperature. The activation energy of 0_{2} uptake was less at lower [O_{2}]_{pkg} and temperature. The predicted activation energy for permeation of O_{2} through the film (

kJ·mol^{-1}) required to maintain close-to-optimum [O_{2}]_{pkg} across the range of temperatures between 0 and 25C was ≈ 60 kJ·mol^{-1}. Packages in which diffusion was mediated through polypropylene or polyethylene would have values

of ≈ 50 and 40 kJ·mol^{-1}, respectively, and would have correspondingly greater tendencies for [O_{2}]_{pkg} to decrease to excessively low levels with an increase in temperature. Packages that depend on pores for permeation would have an

of <5 kJ·mol^{-1}. Our procedure predicted that, if allowed to attain steady-state conditions, packages with pores and optimized to 2 kPa O_{2} at 0C would become anaerobic with as little as a 5C increase in temperature. The results are discussed in relation to the risk of temperature abuse during handling and marketing of MA packaged fruit and strategies to avoid induction of anaerobiosis.
