76. Brown avocado is usually safe if it still smells and tastes normal.
77. Extensive browning can signal age and flavor decline.
78. Oxidation changes appearance faster than it changes food safety.
79. Fresh guacamole should still be refrigerated.
80. The pit gets far too much credit for a job actually being done by oxygen barriers and acidity.
