5.6. Control Measures for Critical Points
[Regeling vervallen per 01-01-2006]
Based on the hazards and risk evaluation and the determination of the critical points
in the production process, the supplier determines which control measures are necessary
to eliminate the identified risks or to control them to an acceptable level. These
control measures must be documented.
Especially when artificial drying, steam injection, technical or technological aid
agents, or mycotoxins are critical points, control measures have to be made clear.
Examples of relevant (generic) control measures:
[Regeling vervallen per 01-01-2006]
Cultivation and Harvesting
[Regeling vervallen per 01-01-2006]
Cultivation and harvest instructions are necessary to guarantee the quality of the
feed material.It concerns for example preventing feed materials getting wet, preventing
of fungus growth, prevention of presence of contamination (for example residues of
pesticides).
Mycotoxins at cultivation, harvesting and/or storage
[Regeling vervallen per 01-01-2006]
Control measures for feed materials or animal feed which are sensitive to mycotoxins,
must in all stages of cultivation, harvesting and storage of the basic products and
storage of the processed feed materials be aimed at making the development of mould
growth asunfavourable as possible (for example choice of race of crop, way of manufacturing,
way of storage). Existing control measures are:
Cultivation
-
● Choose for less sensitive breeds
-
● Apply full crop rotation, without maize before other cereals
-
● Apply a turning up side down soil tillage
Storage
Control of Non-Conforming Products
[Regeling vervallen per 01-01-2006]
The supplier must also ensure that non-conforming feed material are clearly identified
and segregated from both waste and conforming products in a manner that prevents inadvertent
or accidental use, at all stages.
All incidences of non-conforming feed materials shall be recorded and decisions regarding
actions to be taken shall only be made by nominated members of staff.
Non-conforming feed materials or product in process would normally be dealt with in
one of the following ways:
Requirements for reprocessing non-conforming feed materials shall be documented and
any affected feed material be re-evaluated on completion to ensure that the batch
concerned meets specified requirements. Feed materials that do not fully meet a customer
specification shall only be supplied if the customer is notified of the problem in
writing and is prepared to accept them.
Site, Building and Process Equipment Requirements
[Regeling vervallen per 01-01-2006]
It may be necessary to (re)design, (re)construct and maintain buildings such that
conditions within the building are suitable and do not adversely affect the quality,
safety or integrity ofany feed materials either processed or kept in the building.
The production, storage, transport and shipping used by the supplier shall be secure
and prevent unauthorised access.
All equipment (such as sieves, screens, filters, separators, etc) used for processing,
storing and transporting feed materials shall be fit for the purpose for which it
is used.
Such equipment shall be subject to a program me of planned maintenance that ensures
equipment is maintained in safe and hygienic working condition.
The supplier shall keep records of maintenance carried out on all critical equipment.
Intake & Loading Facilities
[Regeling vervallen per 01-01-2006]
The supplier shall ensure that all intake and loading facilities are designed and
constructed in a manner that maintains the quality and safety of feed materials.
Neither discharge nor loading shall be carried out in conditions such that inclement
weather or risks of contamination may affect the raw materials or feed materials being
handled. Intake and loading facilities shall be designed to ensure that access by
birds and other pests is kept to an absolute minimum.
In the case of flat stores, facilities shall be organised to ensure that mud, snow
and other potential contaminants carried by vehicles cannot adversely affect stored
raw materials or feed materials. There shall be sufficient hardstanding (e.g. concreted
area) at store entrances tolimit the tracking of water and mud into the store.
Conveyors and Handling Equipment
[Regeling vervallen per 01-01-2006]
All conveying systems and handling equipment shall be maintained in a sufficiently
clean and hygienic condition to avoid adversely affecting the feed materials they
contact. Risk assessment procedures shall be used to identify and control any hazards
that may arise. Records shall be kept detailing the time and nature of any cleaning
undertaken.
Storage
[Regeling vervallen per 01-01-2006]
Feed materials and products must be stored in such a way that they can be identified
easily and that confusion with other damaging products is prevented. The way in which
these items have to be treated by the supplier, must be included in an instruction.
During storage, rain and stained water must be prevented from entering. Even whilst
they are empty, storage and loading compartments must be covered to prevent rain-entry
and pollution through bird-droppings. The thereby deployed tarpaulins must be clean
and dry. Prior to loading of feeds, the exterior of the vehicle, including chassis,
must be cleared of all visible residues of the preceding load.
Transport
[Regeling vervallen per 01-01-2006]
For transport of feed materials in general it applies that before loading, load compartments
must be empty, clean, dry and free from any remnants and odours of previous cargoes,
in order to prevent load contamination. This includes:
-
● Free of possible "agribulk-unfriendly elements", such as residues of preceding cargo
and/orcleansing activities.
-
● Free of vermin, in the broadest sense of the word (insects and vermin, dead or alive).
In order to comply with this, it may be necessary to clean the load compartment (before
loadingof the feed materials). If cleaning is necessary, this must be done in a way
that is adequate inrelation to the nature of the previous cargoes. Depending on this
nature of the previous cargoes, this can implicate dry cleaning (e.g. with broom)
or - if necessary - cleaning with waterand possibly cleansing agents or even disinfections.
After this cleansing, the load compartmentmust be inspected for cleanness.
For road transport this (cleansing and) inspection may be carried out by the transporter
/road haulage company (truck driver).
In case of ocean, river and rail freight an inspection of the cleanness of the load
compartments(LCI = Load Compartment Inspection) has to be carried out before loading
commences. Furthermore, the loading process has to be monitored/safeguarded, in order
to maintain feed and food safety. This inspection and monitoring may be carried out
by:
-
a) an inspection company at the EN 45000 level, specialised in and accredited for feed/grainsor
liquid agri-bulk, and internationally operating on a certified guarantee system such
asISO 9000 or equivalent;
-
b) a company inspector of the chartering party or, at his request, of the supplying party,
whois included in the company's own quality system as a qualified loading inspector
and whose person, function and ability have been guaranteed.
Furthermore, the load compartment must be adequately shielded to protect the transported
cargo against influence from other transported goods and be provided with resources
to cover the cargo during transport.
In general, hygienic conditions must constantly be preserved during transport. Pollution
with undesired materials and products must be prevented. This includes that mingling
with other products must be prevented. A specific point of attention is that, to obliterate
the spread of BSE(Mad Cow Disease), all possible and necessary preventive measures
must be taken to preclude contamination of feed materials through proteins, forbidden
for ruminants.
For deliveries to GMP-certified companies the road transport must be certified according
toGMP07
Hygienically working
[Regeling vervallen per 01-01-2006]
During all cultivation, harvest, storage and processing steps operations must be performed
hygienically to make sure that the production environment and the personnel can not
contribute to contamination of feed materials. It concerns instructions for personal
hygiene, industrial clothing, treatment of chemicals, general company rules concerning
this, etc. The methods of hygienic working must be documented.
Cleaning
[Regeling vervallen per 01-01-2006]
A supplier must set and perform such measures, that adequate company hygiene is assured.The
cleaning program must include company equipment where applicable, (company) areas
and facilities, installations and (internal) transport systems. Cleaning programs
must be documented, cleaning frequency and used cleaning agents must be registered,
etc.
Any materials considered to be 'waste' shall be visually identified as such and promptly
segregated in a manner that will eliminate the likelihood of accidental or inadvertent
use. Waste material may not be collected or stored in any container that may be used
for finished feed materials. In order to discourage pests and vermin, containers used
to store waste materials shall be covered. They shall also be stored away from feed
material storage or production areas and removed from site as frequently as practical.
All waste shall be disposed of legally.
Pest Control Program
[Regeling vervallen per 01-01-2006]
A supplier must take measures for the exclusion of vermin and to determine and document
a pest control program. It concerns barring out vermin during the cultivation and
harvesting process as well as fighting vermin during storage of feed materials. When
executing pest control programs, acceptable pest control methods and means must be
used.
Identification and traceability of feed materials
[Regeling vervallen per 01-01-2006]
It is of importance in case of problems or questions afterwards, that products in
the chain can be identified and traced. Therefore it is necessary that the grower,
trader and manufacturer keep a detailed administration. In this administration the
relevant data for effective tracing offeed materials is included.
Contamination with specific contaminants
[Regeling vervallen per 01-01-2006]
Contamination or pollution of feed materials and products must be prevented where
possible.Contamination can happen anywhere. Controls shall be in place to protect
feed materials from contamination by foreign bodies.
In particular, intake points, processing equipment, conveying systems and storage
facilities shall be designed and operated to minimise the possibility of ingress.
Operatives, drivers and maintenance personnel shall all be trained and supervised
so as to ensure that the risk of foreign materials ingress is kept to an absolute
minimum.
Wherever possible, process and storage facilities shall be enclosed to avoid contact
with potential contaminants as well as access for pests and vermin. Where this is
not possible, appropriate controls shall be in place to ensure minimal risk to feed
material integrity.
Especially adequate control measures must be taken and documented regarding the following
fields:
Contamination during (artificial) drying in direct contact with combustion gases.
[Regeling vervallen per 01-01-2006]
Important is the quality of the fuel. Control measures could be taken for example
in the form of forbidding unsuitable fuels and prevention of uncontrolled combustion.
It is important to make clear in which way the quality of the fuels and the adjustment
of the drying installation are guaranteed. Extensive control measures are
-
● Specification of the fuel quality and appointments with the supplier, based on risk
evaluation Use only mineral fuels (gas, coal, petroleum) which are suitable according
to the specification of the supplier.
-
● Specification of control measure to avoid contamination of fuels during storage and
transport
-
● Specification of the checks of the fuel's quality
-
● Specification of the adjustment of the burner and dryer installation to avoid incomplete
combustion
Technical and technological aid agents
[Regeling vervallen per 01-01-2006]
The supplier who adds technical and technological aid agents to the feed materials
must apply certain control measures to prevent contamination of the feed materials
Steam injection
[Regeling vervallen per 01-01-2006]
The supplier who uses steam in the production process of the feed materials must be
sure that the feed materials are not contaminated due to the poor quality of the water
he uses. It is important that there are specifications of:
-
● the quality of the water, which is used for steam injection and the technical aid
agents like corrosion preventing agents
-
● the quality control of the water and the technical aid agents
