R.C.S.A. § 22-33-A1
Connecticut standard grades (Repealed)
Cite as Conn. Agencies Regs. § 22-33-A1
The Connecticut standard grades for potatoes shall be the following, which are identical
with the standards established by the United States department of agriculture under
authority of the congress of the United States:
(a) General.
(1) Numbers and letters in parentheses following grade terms indicate where such terms
are defined under definitions.
(2) All percentages shall be calculated on the basis of weight.
(3) The tolerances for the standards are on a container basis. However, individual packages
in any lot may vary from the specified tolerance as stated below, provided the averages
for the entire lot, based on sample inspection, are within the tolerances specified.
(4) When the tolerance specified is ten per cent or more, individual packages in any lot
may contain not more than one and one-half times the tolerance specified, except that
at least one defective and one off-size specimen shall be permitted in a package.
(5) When the tolerance specified is less than ten per cent, individual packages in any
lot may contain not more than double the tolerance specified except that for frozen
potatoes, or those affected by soft rot or wet breakdown, not more than one-tenth
of the packages may contain more than double the tolerance but not more than four
times the tolerance specified, and except that at least one defective and one offsize
specimen shall be permitted in a package.
(b) Grades.
(1) Conn. Fancy shall consist of potatoes of one variety or similar varietal characteristics
which are firm, mature (1), bright (2), well shaped (3), not frozen; which are free
from freezing injury, blackheart, late blight, southern bacterial wilt, ring rot,
shriveling, sprouting, soft rot or wet breakdown (4), hollow heart, and internal discoloration
(5), and free from injury (6) caused by dirt or other foreign matter, sunburn, second
growth, growth cracks, air cracks, cuts, external discoloration, scab, dry rot, rhizoctonia,
other disease, wireworm, other insects or other means (6).
(2) The diameter (7) of each potato shall be not less than two inches.
(3) For long varieties such as Burbank, Russet Burbank, Early Ohio, White Rose, or other
similar varieties, not less than forty per cent of the potatoes in any lot shall be
six ounces or more in weight.

(5) The size of the potatoes may be stated in terms of minimum diameter or minimum weight,
or of range in diameter or weight, or of a certain percentage over a certain size,
following the grade name, but in no case shall the potatoes be below the sizes specified
for this grade. (See Tolerance for Size, (C-7).)
(6) In order to allow for variations other than size, incident to proper grading and handling,
not more than a total of six per cent of the potatoes in any lot may fail to meet

less than one-half, or thirty per cent, shall be two and three-quarters inches, or
larger in diameter.
(9) In order to allow for variations other than size, hollow heart, and internal discoloration,
incident to proper grading and handling, not more than a total of six per cent of
the potatoes in any lot may fail to meet the requirements of the grade, but not more
than three per cent shall be allowed for potatoes affected by southern bacterial wilt,

the potatoes in any lot may fail to meet the requirements of the grade, but not more
than three per cent shall be allowed for potatoes affected by southern bacterial wilt,
ring rot or late blight, and including not more than one per cent for potatoes which
are frozen, or affected by soft rot or wet breakdown. In addition, not more than five
per cent may be seriously damaged by hollow heart and internal discoloration.
(c) Size classification for all grades except Conn. Fancy.
(1) When the potatoes are designated as "Conn. No. 1," "Conn. Commercial" or "Conn. No.
2" without specifying a size classification, it is understood that the potatoes meet
the minimum size specified in the grade but that no definite percentage of the potatoes
is required to be larger than this minimum size.
(2) When potatoes meet the requirements of Size A or Size B as described below, the size
classification may be specified in connection with any of the Conn. grades except
Conn. Fancy, as: "Conn. No. 1, Size A"; "Conn. Extra No. 1, Size A"; "Conn. Commercial,
Size B"; "Conn. No. 1, Size B"; "Conn. No. 2, Size A"; or "Conn. No. 2, Size B"; in
accordance with the facts. When Size A or Size B is used in connection with the grade,
it is not permissible to specify any smaller sizes than those specified under these
designations.
(3) Size A. For long varieties such as Burbank, Russet Burbank, Early Ohio, White Rose,
or other similar varieties, the diameter of each potato shall be not less than one
and seven-eighths inches and not less than forty per cent of the potatoes in the lot
shall be six ounces or more in weight.
(4) For round or intermediate shaped varieties such as Irish Cobbler, Katahdin, Bliss
Triumph, Green Mountain, or other similar varieties, the diameter of each potato shall
be not less than one and seven-eighths inches and not less than sixty per cent of
the potatoes in the lot shall be two and one-quarter inches or larger in diameter.
(5) Size B. For all varieties the size shall be from one and one-half inches to not more
than two inches in diameter.
(6) Other sizes. When any of the above size designations are not used in connection with
Conn. Extra No. 1, Conn. No. 1, Conn. Commercial, or Conn. No. 2 grades, it is permissible
to specify any other minimum size such as "1½ inches minimum," "2 inches minimum,"
or both a minimum and a maximum size as "1⅞ inches to 3 inches," "6 to 10 ounces";
or to specify a certain percentage over a certain size as "25 per cent or more 2¼
inches and larger," "50 per cent or more 5 ounces and larger."
(7) In order to allow for variations incident to proper sizing, not more than three per
cent of the potatoes in any lot may fail to meet the specified minimum size except
that a tolerance of five per cent shall be allowed for potatoes packed to meet a minimum
size of two and one-quarter inches or more in diameter, or six ounces or larger in
weight. In addition, not more than fifteen per cent may fail to meet any specified
maximum size.
(8) When a percentage of the potatoes is specified to be of a certain size and larger,
no part of any tolerance shall be used to reduce such a percentage for the lot as
a whole, but individual containers may have not more than fifteen per cent less than
the percentage required or specified, provided that the entire lot averages within
the percentage specified. For example, a lot specified as twenty-five per cent two
and one-half inches and larger may have containers with not less than ten per cent
two and one-half inches and larger provided the lot as a whole averages twenty-five
per cent two and one-half inches and larger.
(d) Skinning classification.
(1) The following optional skinning classifications are provided as a basis for classifying
lots of potatoes as to the degree of skinning.
(2) "Practically no skinning" means that not more than five per cent of the potatoes in
any lot have more than one-tenth of the skin missing or "feathered."
(3) "Slightly skinned" means that not more than ten per cent of the potatoes in any lot
have more than one-fourth of the skin missing or "feathered."
(4) "Moderately skinned" means that not more than ten per cent of the potatoes in any
lot have more than one-half of the skin missing or "feathered."
(5) "Badly skinned" means that more than ten per cent of the potatoes in any lot have
more than one-half of the skin missing or "feathered."
(e) Unclassified.
(1) Unclassified shall consist of potatoes which have not been classified in accordance
with any of the foregoing grades. The term "unclassified" is not a grade within the
meaning of these standards but is provided as a designation to show that no definite
grade has been applied to the lot.
(f) Definitions. As used in these standards:
(1) "Mature" means that the outer skin (epidermis) does not loosen or "feather" readily
during the ordinary handling and that practically no skin has been removed from the
potatoes.
(2) "Bright" means practically free from dirt or other foreign matter, and that the outer
skin (epidermis) has the attractive color normal for the variety.
(3) "Well shaped" means the normal shape for the variety and that the potato is not pointed,
dumbbell-shaped, excessively elongated, or otherwise ill-formed.
(4) "Soft rot or wet breakdown" means any soft, mushy, or leaky condition of the tissue
such as slimy soft rot, leak, or wet breakdown following freezing injury or sunscald.
(5) "Internal discoloration" means discoloration such as is caused by net necrosis or
any other type of necrosis, stem-end browning, internal brown spot, or other similar
types of discoloration not visible externally, except blackheart.
(6) "Injury" means any defect which more than slightly affects the edible or shipping
quality, or the appearance of the individual potato or the general appearance of the
potatoes in the container, or which cannot be removed without a loss of more than
two per cent of the total weight of the potato including peel covering defective area.
(7) "Diameter" means the greatest dimension at right angles to the longitudinal axis.
The long axis shall be used without regard to the position of the stem (rhizome).
(8) "Fairly well shaped" means that the appearance of the individual potato or the general
appearance of the potatoes in the container is not materially injured by pointed,
dumbbell-shaped or otherwise ill-formed potatoes.
(9) "Fairly clean" means that, from the viewpoint of general appearance, the potatoes
in the container are reasonably free from dirt or other foreign matter and that individual
potatoes are not materially caked with dirt or materially stained.
(10) "Damage" means any injury or defect which materially injures the edible or shipping
quality, or the appearance of the individual potato or the general appearance of the
potatoes in the container, or which cannot be removed without a loss of more than
five per cent of the total weight of the potato including peel covering defective
area. Any one of the following defects or any combination of defects the seriousness
of which exceeds the maximum allowed for any one defect shall be considered as damage:
(A) Second growth or growth cracks which have developed to such an extent as to materially
injure the appearance of the individual potato or the general appearance of the potatoes
in the container. (B) Air cracks which are deep, or shallow air cracks which materially
injure the appearance of the individual potato or the general appearance of the potatoes
in the container. (C) External discoloration, when skinned areas on individual potatoes
are materially affected by dark discoloration, or when the general appearance of the
lot is materially affected by discoloration. (D) Shriveling, when the potato is more
than moderately shriveled, spongy or flabby. (E) Sprouting, when more than ten per
cent of the potatoes have sprouts over three-fourths of an inch long. (F) Surface
scab which covers an area of more than five per cent of the surface of the potato
in the aggregate. (G) Pitted scab which affects the appearance of the potato to a
greater extent than the amount of surface scab permitted or causes a loss of more
than five per cent of the total weight of the potato, including peel covering defective
area. (H) Rhizoctonia, when the general appearance of the potatoes in the container
is materially injured or when individual potatoes are badly infected. (I) Wireworm,
grass root or similar injury, when any hole, on potatoes ranging in size from six
to eight ounces, is longer than three-quarters inch or when the aggregate length of
all holes is more than one and one-quarter inches. Smaller potatoes shall have lesser
amounts and larger potatoes may have greater amounts, provided the removal of the
injury by proper trimming does not cause the appearance of such potatoes to be injured
to a greater extent than that caused by the proper trimming of such injury permitted
on a six to eight ounce potato. (J) Dirt, when the general appearance of the potatoes
in the container is more than slightly dirty or stained, or when individual potatoes
are badly caked with dirt or badly stained; or other foreign matter which materially
affects the appearance of the potatoes.
(11) "Serious damage" means any injury or defect which seriously injures the edible or
shipping quality, or the appearance of the individual potato or the general appearance
of the potatoes in the container, or which cannot be removed without a loss of more
than ten per cent of the total weight of the potato, including peel covering defective
area. Any one of the following defects or any combination of defects the seriousness
of which exceeds the defects or any combination of defects the seriousness of which
exceeds the maximum allowed for any one defect shall be considered as serious damage:
(A) Dirt, when the general appearance of the potatoes in the container is seriously
affected by tubers badly caked with dirt; or other foreign matter which seriously
affects the appearance of the potatoes. (B) External discoloration, when skinned areas
on individual potatoes are seriously affected by very dark discoloration, or when
the general appearance of the lot is seriously affected by discoloration. (C) Fairly
smooth cuts such as are made by the digger or by a knife to remove injury, when both
ends are clipped, or when more than an estimated one-fourth of the potato is cut away,
or, in the case of long varieties, when the remaining portion of the clipped potato
weighs less than six ounces. Irregular types of cuts which seriously affect the appearance
of the individual potato, or which cannot be removed without a loss of more than ten
per cent of the total weight of the potato, including peel covering defective area.
(D) Shriveling, when the potato is excessively shriveled, spongy, or flabby. (E) Surface
scab which covers an area of more than fifty per cent of the surface of the potato
in the aggregate. (F) Pitted scab which affects the appearance of the potato to a
greater extent than the amount of surface scab permitted or causes a loss of more
than ten per cent of the total weight of the potato including peel covering defective
area. (G) Wireworm, grass root or similar injury, when any hole, on potatoes ranging
in size from six to eight ounces, is longer than one and one-quarter inches or when
the aggregate length of all holes is more than two inches. Smaller potatoes shall
have lesser amounts and larger potatoes may have greater amounts, provided the removal
of the injury by proper trimming does not cause the appearance of such potatoes to
be injured to a greater extent than that caused by the proper trimming of such injury
permitted on a six to eight ounce potato.
