activities and projects with GMO in contention.
Sole Paragraph. The main technician is responsible for
fulfilling the biosafety norms in accordance with CIBio's
recommendations, and with CTNBio's Normative Resolutions of
CTNBio, and should ensure that the technical and support
teams involved in the activities with GMO and its
derivatives receive appropriate training in biosafety and

reports of the corrective actions already taken and the
names of the people and authorities that have been
notified, within five days from the date of the event.
Paragraph 2 – The communication to CTNBio and to its
pertinent registration and inspection organs and entities
does not exempt CIBio from any other obligation it may have

CHAPTER IV
RISK CLASSIFICATION
Art. 7. GMOs will be classified in four risk classes,
adopting as criteria the pathogenic potential of the donor
and receptor organisms, the transferred nucleotide
sequences, their expressions in the receptor organism, the
resulting GMO, and its adverse effects to human and
animal's health, to vegetables and to the environment.
Paragraph 1. For genes that codify products that are
harmful to human and animal health, to vegetables and to
the environment, the vector used shall have limited
capacity to survive outside the contention environment.
Paragraph 2. Every genetically modified organism should
have a marker capable of identifying it amongst a
population of the same species.
Article 8. The GMO risk classes will be defined on the
following form:
I – Risk Class 1 (low individual risk and low risk for the
community): The GMO that has DNA/RNA sequences from the
donor and receptor organism that does not cause aggravation
to human and animal's health and adverse effects to
vegetables and to the environment;
II – Risk Class 2 (moderate individual risk and low risk to
the collectivity): The GMO that has DNA/RNA sequences from
the donor or receptor organism with moderate risk of
aggravation to human and animal's health, that has low risk
of dissemination, and of causing adverse effects to
vegetables an to the environment;
III- Risk Class 3 (high individual risk and moderate risk
to the community): GMO that has DNA/RNA sequences from the
donor or receptor organism, with high risk of aggravation
to human and animal's health, that has low or moderate risk
of dissemination and of causing effects to vegetables and
to the environment;
IV- Risk Class 4 (high individual risk and high risk for
the collectivity): GMO that has DNA/RNA sequences from the
donor or receptor organism with high risk of aggravation to
human and to animal's health, which has high risk of
dissemination, and of causing adverse effects to vegetables
and to the environment.
Paragraph 1. The resulting GMO risk class shall not be
inferior to the risk class of the receptor organism, except
in cases where there is reduction of the virulence and
pathogenesis of GMO.
Paragraph 2. The GMO that has DNA/RNA sequences of
organisms or infectious agents without potential of
expression in activities and projects proposed will be
classified in the same risk class of the receptor organism.
Paragraph 3. The GMO that has DNA/RNA sequences deriving
from higher risk class organism and with potential of
expression may, at CTNBio's discretion, be classified in
the risk class of their receptor organism, as long as it is
recognized as not associated to toxicity or pathogenesis in
activities and projects proposed.
Paragraph 4. For risk classification, one should also
consider:
a) The possibility of recombination of sequences inserted
in the GMO, that take to the complete and functional
reconstitution of genomes of infectious agents;
b) Other processes that generate an infectious genome;
c) Genes that codify toxic substances to men, animals,
vegetables or that cause adverse effects to the
environment;
d) Genes resistant to antibiotics of wide clinical use.
Paragraph 5. The following are classified as risk class 2
or higher:
a) those vegetables genetically modified that are weeds or
spontaneous plants, that may cross with the latter in an
area that make such crossing possible, generating fertile
descendents with bigger capacity of invasion and damage to
the environment than the parents; and
b) Organisms genetically modified that are biological
vectors of agents that cause aggravation to human health,
animals, vegetables or to the environment.
Paragraph 6. The GMO that becomes more able to survival on
the environment than the native organisms, and that, at
CTNBio's discretion, represents a potential menace to
biodiversity, may have its risk class increased.
Paragraph 7. The following lists will be used as base for
information of infectious agents for humans and animals by
risk class: the list published by the Ministry of Health,
the list of plants quarantine by risk class, published by
the Ministry of Agriculture, Cattle Breeding and Supply and
the list of invasive plants published by the Ministry of
Environment.

II – the entrance to the installations should be kept
locked, being the access restricted to people accredited by
the institution's CIBio;

consideration the kind of genetically modified animal to be
kept and manipulated, but always taking the necessary care
to prevent it from escaping;
IV – all areas that allow ventilation (including the
entrance and exit of air conditioning) should have physical
barriers to prevent insects and other animals from passing;
V – drains and other similar devices, if there is any,
should have barriers to avoid the possibility of escaping,
or the entrance of contaminated material;
VI – animals from different species, and not involved on
the same experiment should be allocated in separate
physical areas;
VII – the installations of air curtains with flow from the
top to the bottom on the insect room access doors is
recommended;
VIII – aquiculture tanks should have water renovation in
separate system, and all the disposable water should go
through sewage tank with disinfection, before going to
pluvial net;
