Like many naturally grown foods, pecans are susceptible to pests, fungi, and damage from harvesting and handling. To enjoy the best pecans, keep these factors in mind:

Shell shape:

 As pecans grow, they form inside the husk as nutrients travel through the husk and shell.

Dry weather, low-nutrient soil, and insect damage are all possible interruptions to this growing process. When a pecan hasn’t grown properly, it tapers towards the tip end, so look out for this visual sign if a pecan is bad.


High-quality pecans should exhibit a smooth, uniform color. For these striped varieties, look for a clear definition between the color of the stripe — black or very dark — and the light tan color of the pecan’s shell. Consistent color and definitive stripes are both excellent indicators of quality pecans.
