Oats Pest Prevention

Oats, a common cereal found in many households, are prone to being invaded by various pests during both storage and transportation. These pests include the granary weevil (Sitophilus granarius), cadelle beetle (Tenebroides mauretanicus), rust-red grain beetle (Cryptolestes ferrugineus), saw-toothed grain beetle (Oryzaephilus surinamensis), European grain moth (Nemapogon granellus), and Angoumois cereal moth (Sitotroga cerealella). The presence of these pests poses a significant risk to the quality and safety of stored oats.

The damage caused by these pests, through chewing, not only compromises the integrity of the oats but also results in increased respiration in the cereal, leading to the formation of hot spots. This, combined with the pests' metabolic activity, initiates the generation of heat and moisture within the stored oats. These conditions create an ideal environment for mold growth, and excessive moisture levels can facilitate bacterial proliferation.

The consequences of insect infestation go beyond physical damage, as self-heating can occur, causing the depreciation of oats and, ultimately, complete loss. The primary breeding grounds for these pests are poorly cleaned warehouses, holds, and containers. Addressing this fundamental issue is crucial in preventing infestations and preserving the quality of stored oats.

Additionally, oats face additional threats from rodents like rats and mice, which can act as disease vectors and introduce contamination to the cereal. To mitigate these risks, thorough inspections by independent inspectors are necessary before loading oats into holds or containers. Obtaining certification that confirms the absence of pest infestations becomes a critical step in ensuring the safety and quality of the stored oats.

In conclusion, combating contamination by oats weevils involves understanding the various pests that pose a threat, addressing the root causes of infestation, and implementing rigorous inspection procedures before storage and transport. By adopting these preventive measures, we can protect oats from the harmful effects of insect damage and contamination, preserving their nutritional value and overall quality for consumption.

High quality oats grain for processing

Common white oats, Avena sativa, are by far the most widely grown species. Oats are traditionally grown in moist, temperate regions.

Oat grain serves dual use as both a human food, chiefly as oatmeal or a component of breakfast cereal products, and as a high quality feed for horses and other livestock.

It has higher protein level among the cereal with 12 to 20% protein in the dehulled kernel and 9 to 15% in the whole grain, depending on genotype and environmental growth conditions.

Oats to be milled for human consumption should be plump, sound and free from heat damage, foreign odors, wild onion seed, smut, must and molds. Good quality oats are free form dust and are not dull colored.

Usually only grade 1 or grade 2 oats are accepted for food processing. Plumpness contributes to a good yield and desirable texture in the finished oatmeal. Grain plumpness and uniformity reducing the portion of small grains also improved milling productivity.

Heat or mold damage, or the presence of foreign materials, leads to off-color particles and off-flavors.

Oats weevil contamination

Oats weevil contamination
Oats may be infested by the following cereal pests during storage and transport:
granary weevil (Sitophilus granarius)
cadelle beetle (Tenebroides mauretanicus)
rust-red grain beetle (Cryptolestes ferrugineus)
sawtoothed grain beetle (Oryzaephilus surinamensis)
European grain moth (Nemapogon granellus)
Angoumois cereal moth (Sitotroga cerealella)


The chewing damage caused by the cereal pests brings about increased respiration in the cereal (hot spots) and this, associated with the metabolic activity of the pests themselves, promotes evolution of heat and moisture, which in turn provide favorable living conditions for molds and subsequently, at very high moisture levels, for bacterial growth.

Insect infestation may result in self-heating which ultimately gives rise to depreciation and finally total loss.Inadequately cleaned warehouses, holds and containers are generally the root cause of insect infestation.

Cereal is also at risk from rats and mice, which can act as disease vectors and contaminate the cereal.Before loading, holds/containers should be examined by an independent inspector for infestation by pests of any kind and an appropriate certificate obtained.
