Screenings - Chapter 23 | Official Grain Grading Guide

Grading factors

Ergot (ERG)

Ergot (ERG)

Ergot is a disease that attacks cereal grains and results in a fungus growth in place of the kernel of grain. The disease produces elongated fungal bodies that have a purplish-black exterior, a purplish-white to off white interior, and a relatively smooth surface texture.

Excreta (EXCR)

Excreta (EXCR)

Excrement from any animal including mammals, birds and insects.

Important:

Wear gloves and a mask to handle any samples that you suspect may contain excreta.

Heated, fireburnt and odour (HTD, FBNT, ODOR)

Heated, fireburnt and odour (HTD, FBNT, ODOR)

Screenings that are not sweet are graded according to their composition with the condition included in the grade name.

Heated, fireburnt and odour for screenings.
If odour is the grade determinant and there is . . . Then the grade is . . .
An excessive objectionable odour not associated with the quality of the grain, but not heated or fireburnt Screenings, (Grade Name) Account Odour
An excessive heated odour Screenings, (Grade Name) Account Heated
An excessive fireburnt odour Screenings, (Grade Name) Account Fireburnt
Injurious seeds

Injurious seeds

The following seeds are designated by the Feeds Regulations as detrimental to animal health:

  • bird rape
  • cockle, cow
  • cockle, purple
  • darnel
  • false flax, flat-seeded
  • false flax, small-seeded
  • false flax, western (large seeded)
  • mustard, black
  • mustard, Indian
  • mustard, hare's-ear
  • mustard, tumble
  • mustard, wild
  • mustard, wormseed
  • stinkweed
Knuckles and straw, (KNKLS&STRAW)

Knuckles and straw, (KNKLS&STRAW)

Knuckles include empty wheat heads, nodes of stems and short pieces of straw up to approximately 2.5 cm in length.

Mustard seed (MUS)

Mustard seed (MUS)

Common wild mustard and hare's ear mustard seed are designated as injurious in the Canada Feed Regulations.

Other domestic grains

Other domestic grains

Other domestic grains are any grains other than wheat, rye, barley, oats, triticale, flaxseed, solin, rapeseed, canola, domestic mustard seed and pulses.

Other large seeds (OLSDS)

Other large seeds (OLSDS)

Other large seeds are seeds not designated as injurious in the Canada Feed Regulations. They include lady's thumb and pale smartweed.

Sclerotinia sclerotiorum (SCL)

Sclerotinia sclerotiorum (SCL)

Sclerotinia sclerotiorum is a fungus producing hard masses of fungal tissue, called sclerotia. The sclerotia vary in size and shape, have a coarse surface texture, vary in exterior color from dark black to gray to white and have a pure white interior.

Soft earth pellets (SEP)

Soft earth pellets (SEP)

Soft earth pellets include soft fertilizer pellets and any other non-toxic material of a similar consistency.

Stones (STNS)

Stones (STNS)

Stones include hard shale, coal, hard earth pellets, fertilizer pellets and other non-toxic materials of similar consistency.

Other factors

Other factors

By-products of a manufacturing process

By-products of a manufacturing process are materials such as malt sprouts, oat hulls, ground and pelleted material. They do not qualify as grain screenings.

If inspection is requested on material that is wholly or partly processed grain screenings, it is graded Sample according to the dominant product, for example, Sample Malt Sprouts, Sample Screenings, Ground; Sample Oat Hulls.

Pelleted screenings

When official weighing or inspection of pellets made from Canadian grain screenings is requested, the official description is Canadian ground and pelleted screenings.

At the request of a shipper, you may show the prime source of screenings in parentheses following the description, for example, Canadian ground and pelleted screenings (flaxseed).

If you are in doubt about the source, you may request a letter of certification from the shipper certifying the source of the screenings. Shippers may also request to have the word grain included in the description of the pellets, for example, Canadian ground and pelleted grain screenings.

Pellets received into terminal elevators made from processing residues of agricultural products are described as simply as possible, for example, Canadian canola extraction pellets, Canadian wheat bran pellets, Canadian beet pulp pellets. You must be reasonably certain of the source or country of origin.
