A vacuum-packed fish fillet is labeled to keep frozen until use. Why does the label warn against thawing it inside the package?
a.The sealed package has no oxygen, which favors botulism toxin
b.The sealed package traps moisture, which always softens the fillet
c.The sealed package blocks the walk-in cooler's cold air circulation
d.The sealed package hides the fillet's original harvest date
解析
Reduced-oxygen packaging removes the oxygen that normally keeps Clostridium botulinum in check, so the fish must be removed from the package before or immediately as it thaws under refrigeration. Texture, air flow, and labeling are quality and record concerns, not the reason for the warning.
