A brief Synopsis of
PPECB Food Safety Criteria & A Checklist
Intended for companies engaged in transporting
products of plant origin for export
Management
-
Establish a register of all vehicles
including the registration and
chassis numbers.
-
Create a register of all chemicals
used to clean vehicles including
the supplier's specification.
-
Water used for cleaning must be
potable (see specification as
published).
-
Temperature monitoring
equipment to be calibrated every
six months.
-
Drivers to be trained in how to
manage temperature monitoring
equipment and the fridge unit.
-
Drivers to be equipped with a
communication means in case of
breakdown or malfunction.
-
Transport of mixed loads must
take into account compatibility,
storage and handling.
-
Vehicles and equipment must be
subjected to appropriate regular
maintenance to ensure effective
and continuous functionality and
minimise breakdowns.
-
Make sure you have all of the
above information in respect of
any sub contractor you may
engage and their vehicles.
Traceability
• A record of each load must be
maintained. The following must
be included:
-
Truck and trailer identification
numbers.
-
Driver's name.
- Where was the product loaded?
- Temperature and condition of
the product when loaded.
Person in charge at the loading
point to sign off.
- Product type.
- Date and time of departure
from loading point.
- Date and time of arrival at
destination.
- Date and time of off-loading at
destination.
- Temperature during off-loading
at destination.
- Acceptance of load in good
condition by receiving points.
- Name and address of offloading
point.
- A document showing a hazard
analysis of the transport
element including biological,
chemical and physical hazards.
Vehicle Spot Checks
-
Look for signs of de-lamination,
damaged insulation, holes, cracks
and dirt.
-
Is the fridge unit clean?
-
Do the door seals ensure an
airtight seal? Are all rubbers in
good repair?
-
Are the trucks and/or trailers
clean, free from taint, odour, dry
and grease-free?
Scope for Improvement
Based on International Institute of
Refrigeration (IIR)
Recommendations
Priorities
-
Provide consumers with safe,
wholesome foods.
-
Comply with all rules governing
hygiene.
-
Make best use of high
performance energy-efficient
equipment.
-
Raise awareness among end-users
regarding longterm economic and
environmental benefits of energyefficient
equipment.
-
Major energy savings can be
achieved in the refrigerated
transport of chilled products.
Keys
to improving cold chain and food safety standards
-
Airflow - speed control over fridge
unit - evaporator/condenser.
Control over temperatures to
transport chilled products is more
sensitive than transporting frozen
products. If it is too cold, products
are damaged. If too high, product
life is shortened.
-
Insulation - no substitute for high
efficiency. Panel, roof and floor
thickness, door seals etc.
-
Logistics - establish efficient load
modules.
-
Refrigeration power - responsible
choice over equipment; energyefficient
fridge motors is essential.
-
Temperature control - close
monitoring of air temperature.
Influence of air guidance devices
(airflow ducting), impact of
stowage (pallet stacking and
packaging) on air and temperature
distribution. Define the
relationship between air and cargo
temperatures.
Point to Ponder
The IIR estimates diesel power
requirements for refrigerated trucks
are 11 kW for a typical rigid van to
23 kW for a trailer unit, giving an
overall figure of around 0.05 kW/hr
per ton/km. This high power is
necessary to obtain a fast temperature
pull down and fast recovery with
many door openings.
