SS8 - IMPORTS - COFFEE, DATES AND DATE MATERIAL
1. Coffee - Wharf Examination - Note: Wharf Examine a minimum of six bags
of coffee beans regardless of lot size. If a significant number of defective
beans or significant contamination is found during the examination of these six
bags, continue the examination using the following schedule, which applies for
both Wharf Examination and samples for laboratory analysis:
LOT SIZE |
NO. BAGS TO BE SAMPLED |
100 or less |
6 bags |
101 - 200 |
10 bags |
201 - 1000 |
15 bags |
over 1000 |
20 bags |
Sample each bag with a trier, collecting 1/2 pt. of beans from the top and
1/2 pt. from the bottom of the bag. The total quantity of beans taken from each
bag must be the same, since both wharf and laboratory examinations are to be
performed on a composite sample of all beans collected. Shake each sub on a #8
sieve nested in a pan. Dump the sifted beans from each sub into a bag of
sufficient size to hold and permit mixing all of the subs collected from the
lot. Composite the subs. Do not maintain individually.
- Macroscopic Filth Examine the siftings for macroscopic filth (live and dead
whole insects, excreta pellets, extraneous material and sweepings), reporting
findings for each sub separately. See IOM 427.04.
Transfer macroscopic filth, including all sifted material to a second bag and
submit to the laboratory for confirmation. If live insect infestation is
encountered, freeze
the filth
portion containing the insects and the composite coffee bean sample. The lot
will be detained if a live insect infestation is encountered, however, proceed
with the defect bean examination since the reconditioning process will depend on
the results.
- Defect Bean Examination Thoroughly mix the composite sample of coffee beans
and remove three-hundred beans at random. Examine each individual bean visually
(or at a 5X magnification) for insect tunneling and mold damage. Count as moldy
only those beans with 1/4 or more of the surface being moldy. Note: Each
district office has examples of the various types of reject beans.
- Accept the lot if twenty or less rejects are found and discard the sample.
Report your wharf examination into FACTS
or OASIS, depending on your assignment; no Sample Collection Report is
necessary.
- If twenty-one or more rejects are detected, return beans examined to the
composite and submit to the laboratory. You may discontinue the examination when
twenty-one rejects are detected. When a sample is submitted to the laboratory,
all wharf examination time is reported as a field exam in FACTS and the sample
collection time is reported as an import sample collection. All necessary
documents for an import sample collection must be completed.
2. Dates & Date Material - Filth
In the laboratory, dates, like
in-shell nuts are sampled in accordance with a sequential sampling program, i.e.
all subsamples are composited, and 100 dates are sampled at a time,
repetitively, until such time they either exceed or fall under certain reject
numbers. It is not uncommon to have to examine 3 to 6 (100 date) repetitions. It
is therefore important for each subsample to contain at least 200-300 dates or 2
lbs of date material. Sample according to the following schedule:
NUMBER OF SUBSAMPLES REQUIRED

* Schedule is based upon unit containers
weighing between twenty and one-hundred pounds. For containers exceeding
one-hundred pounds each, consider as two or more containers. For example, a
one-hundred and fifty pound container is considered as two containers; a
three-hundred pound container as three containers, etc.
- Identify each subsample separately.
- Each lot will be a separate sample.
Reconditioning, if possible, will be based on lot numbers.
- Do not sample jujubes as dates. These are usually labeled as Chinese Red
Dates, Dried Red Dates, or Honey Dates. Jujubes are not considered to be
misbranded when called Chinese Red Dates, etc., because of the long standing use
of these names. Sample jujubes following the above schedule.
- If live insects are noted, include these as part of the sample collected and
report on the C.R. which subs contained the insects and how many insects, adult
or larvae, were noted. If live infestation is noted, place all subs from the lot sampled in large
plastic whirlpak bags and freeze or place in a cooler on dry ice.
