Almonds are a popular snack and ingredient in different recipes across the globe. They are not only delicious, but they are also nutritious. They contain healthy fats, fiber, protein, vitamins, and minerals that help promote good health.

However, like any other food, almonds are prone to contamination by harmful microorganisms that can cause infection and illness in humans. Here are some signs to look out for to know when to discard almonds with signs of infection.

Sour or Musty Smell

One of the ways to know that your almonds are infected is by their smell. Fresh almonds should have a sweet and nutty aroma. But if you notice a sour or musty smell, it is a sign that the almonds are contaminated with mold or bacteria.

Mold can cause respiratory problems in susceptible individuals like those with allergies and asthma. Bacteria can cause food poisoning symptoms like stomach upset, diarrhea, and vomiting.

Discolored or Slimy Appearance

Another way to know that your almonds are contaminated is by their appearance. Healthy almonds have a brownish skin color and a dry texture.

But if you notice that the almonds are discolored, that is, they have a green, black, or white mold on them, it is a sign of contamination. Also, if the almonds are slimy, they are likely spoiled and should be discarded. Spoilage can occur when the almonds are stored improperly, and high moisture content encourages the growth of spoilage microorganisms.

Presence of Weevils or Other Insects

Almonds are susceptible to infestation by insects like weevils, beetles, moths, and mites. Weevils are small, dark-brown insects that infest the nuts.

They lay their eggs on the nut’s surface, and when the egg hatches, the larvae feed on the nut’s kernel. Beetles, moths, and mites also feed on the almonds and can cause contamination. If you notice any weevils or insects in your almonds, it is a sign of contamination and should be discarded.

Stale or Rancid Taste

Almonds that have gone stale or rancid have an unpleasant taste. When the almonds are stale, they lose their crunchiness and become soft and chewy. Rancid almonds have a bitter or sour taste due to oxidation of the healthy fats in them.

Stale and rancid almonds can cause digestive upset and should be discarded.

Expired Date

Almonds, like any other food product, have a shelf life. They can go bad if not stored properly or if kept past their expiration date. Almonds that are past their expiration date may be contaminated with harmful bacteria or mold.

It is advisable to check the expiration date on the almonds’ packaging before purchasing them and to store them in an airtight container away from moisture and heat to prolong their shelf life.

Cross-Contamination

Cross-contamination can occur when the almonds come into contact with contaminated surfaces or prepared with contaminated utensils.

For example, If you use the same cutting board and knife used for cutting raw chicken to chop almonds, you can contaminate the nuts with harmful bacteria. It is essential to use clean utensils, cutting boards, and surfaces when preparing almonds to avoid cross-contamination.

Conclusion

Almonds are a delicious and healthy snack, but they are susceptible to contamination by harmful microorganisms. It is essential to know the signs of contamination to avoid consuming contaminated almonds that can cause illness and infection.

Discard almonds with a sour or musty smell, discolored or slimy appearance, presence of weevils or other insects, stale or rancid taste, expired date, and cross-contamination.
