This is the ninth article in a series dedicated to preparing
a farm food safety plan. Remember you may not need a third party audit; it depends on who is purchasing
your produce. However, everyone should
have a food safety plan.
The farm review is an overview of how you minimize the
chance of contamination through irrigation waters, wild animals and past land
use. This can be as simple as three
paragraphs, one focusing on irrigation waters, the next on wild animal activity
on the farm and the last on the previous use of the land. The following items should be included:
Irrigation waters
-
What is the source(s) of irrigation water used
on the farm?
-
How do you irrigate your crops with these
waters?
-
How often, when and what, do you test irrigation
waters for to determine possible contaminants?
-
If barriers are used around the water areas
indicate what is used.
-
Is there a septic system, and if so where is it
located and does it pose a contamination risk?
-
Are there any off farm sewage areas that might
pose a potential contamination risk to the farm?
-
Are there any animal production facilities on
the farm, or on adjacent properties? If
so how close are they to your production areas?
-
Are manures or municipal biosolids (note we do
not recommend the use of biosolids in vegetable production)used as a soil
amendment? If so document how and when they
are received, stored, and applied.
-
How are pets and wild animals excluded from
growing areas?
-
If hunting is allowed, indicate the timing and
that a predation permit is obtained for out of season hunting.
-
When and how are fields monitored for animal
activity prior to harvest?
-
What is done if animal activity is found in the
fields?
-
Does the farm have manure storage? If so where are they and what measures are
taken to prevent leaking, overflow and runoff?
-
If livestock is kept on the farm what are the
measures taken to prevent access to irrigation water sources and equipment?
Manure and Municipal
Biosolids
-
Is raw manure used on the farm? If so:
o Keep
application records showing that the raw manure is incorporated at least 2
weeks prior to planting, and a minimum of 120 days prior to harvest.
-
Is treated manure used on the farm? If so:
o The
treated manure should be properly treated, composted or exposed to
environmental conditions that would lower the pathogen levels.
-
Is composted manure used on the farm? If so:
o The
composted manure should be properly treated, composted or exposed to
environmental conditions that would lower the pathogen level.
-
Is there evidence of any imminent risk of
contamination of the soil during any previous use of the land?
-
How was the land previously used?
-
Is the land subject to flooding? If so when and how.
Lastly you should indicate here that each field is given a
unique code/number so that traceability can be ensured.
