2. Acrylamide in panela3. Arsenic in rice4. Mycotoxins in Cereals5. Organochlorines in meat and milk6. Mercury in fish
GROUP FOR FOOD SAFETY RISK ASSESSMENT (UERIA)National Health Institute of Colombia
• We are a technical and scientific group aimed to provide scientific support to the Sanitary and Phytosanitary authorities, who are responsible of adopt or enforce food safety measures and formulate policy-making processes.
• UERIA follows risk assessment techniques developed by relevant international organizations, such as Codex Alimentarius (FAO/WHO).
Challenges
• From its creation in 2009, UERIA group has performed several studies in hazard/food combinations, systematic reviews and scientific concepts about relevant issues for Colombian food safety.
• Through UERIA Colombian Government is working to improve food safety standards of national production aimed to face international challenges derived from current free trade agreements. (USA, Canada, EFTA, Mexico, UE, Chile, and others), as well as coming agreements (Korea, Japan, Turkey Costa Rica)
Why?
Codex International Standard of sugar cane “Panela”. The possibility of acrylamide in panela. caused by chemical reactions between the components
due to changes in temperature and pH in some foods.
Terms of reference (TOR)
1. ¿Does the presence of acrylamide in panela a risk factor for health?
2. ¿ Which are the sources of Acrylamide in Panela?
3. ¿ What is the DMU of acrylamide in food?, What are those levels?
4. ¿ What are the techniques for the determination of acrylamide in food?
Conclusions
• The presence of Acrylamide in foods is a risk factor for health and this chemical hazard is classified in Group 2A by IARC, considering a possible carcinogen.
• Acrylamide on panela, it should be noted that acrylamide is not a food additive is a product of the Maillard reaction, this being a reaction which occurs in the presence of reducing sugars and a free amino group (for example the asparagine) that may be present in raw food materials. The cane juice (raw material panela) has reported the presence of reducing sugars and asparagine in low concentrations.
Conclusions
•The term DMU can not be applied to acrylamide, it is not a food additive.•Gas chromatography coupled to mass spectrometry (GC-MS) and liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) as the most used techniques by international agencies and scientists to determine acrylamide in food research.
Recommendations• Priority is a chemical characterization of sugar cane juice and sugarcane
production region. This should be focused on the determination of reducing sugars and free amino acids.
• Sampling plan panela-producing region that includes the monitoring of acrylamide in the final product.
• Promoting research by academia or research groups to document relevant information to the presence of acrylamide in sugar.
• Encourage technological development in the laboratories of the country, especially in the actions they perform inspection, monitoring and control in food, in order to have reliable methodologies to report results of the acrylamide content in panela and other foods

Why?• Arsenic: naturally occurring mineral.• Presence in groundwater.• Inorganic arsenic (III) and (IV) IARC
carcinogen for humans.• Arsenicosis (skin, lung and kidney
cancer)• IDMT rice is 25 times higher than the
contribution from drinking water China.
• Study by INVIMA requires analyzing information and its impact on public health.
TOR
1. The levels of arsenic in Colombian rice, may even be considered as a risk for the population?
2. The possible sources of arsenic may contaminate rice (presence in soils, irrigation water or agricultural inputs)?
Scope and Limitations
• We only have total arsenic monitoring in rice
• The document not include water and fish
• Not include also poisoning associated with occupational exposure
• The study was limited to raw white rice
Prevention and Control• Water used to irrigate crops should not
exceed 0.1 mg Arsenic / liter• The rainfed crops, decrease the
bioavailability of Arsenic and its accumulation in the plant.
• Improve drainage in soils used for rice cultivation.
• No arsenical pesticides• Control of suppliers in production.• Vegetarian group associated with high
consumption of rice.• Use potable water in washing and
preparing the rice.

Mycotoxins in Cereals
Risk Assessment of Aflatoxin B1 (AFB1) in corn Risk Assessment of Aflatoxin B1 (AFB1) in corn arepa in Colombiaarepa in Colombia
Why? Corn is one of the most consumed foods
in Colombia.
Arepa is a traditional food.
Increased consumer promotion programs and production of this product.
Program managers have interested in monitoring the health status of this product.
TOR
1. What is the substrate pair (maize, wheat and rice) - mycotoxin (DON and AFB1) higher risk for the Colombian population, based on the exposure assessment?
2. Based on the selected pair in the TOR 1, What are the most consumed products in the country that can generate risk Colombian population?
3. What are the measures of prevention and control recommendations in order to reduce contamination of the selected products in the TOR 2?
Scope and objectives
Develop a qualitative risk assessment for the selected pair, identify prevention and control recommendations propose, in response to TOR 2 and TOR 3.
According to the FAO the presence of fungi and mycotoxins can be reduced mainly by the application of good agricultural practices during harvesting, drying and storage.
Preventing mycotoxins focuses on two strategies:
1.Prevent the synthesis of mycotoxins in agricultural products
2.Food decontamination by removal or destruction of mycotoxins
Prevention and control recommendationsPrevention and control recommendations
• Support and strengthening of inspection programs at ports, airports and border crossings
• Refresh the current regulations on control and levels of mycotoxins in foods.
• Expand research on mycotoxins including greater coverage in food, and in the studied mycotoxins. Also that analytical methods are quantitative.
• Strengthen the infrastructure of existing laboratories for mycotoxin analysis.

Why?• Persistent organic pollutants (POPs) are
associated with environmental damage and a variety of toxic effects in animals and humans.
• Persistence, bioconcentration and biomagnification through the food chain.
• There are prohibitions and restrictions on the use, sale and purchase of organochlorine pesticides, however, still residues of these pesticides in the environment.
• Stockholm Convention monitoring and study of the presence of POPs in food.
TOR
1. What organochlorine pesticides could be found as residues in bovine meat and milk in Colombia?
2. From predictive estimates and results of national studies of organochlorines in meat and milk in Colombia, compared with the current legislation of the country, which of organochlorine pesticides identified as residues in the TOR 1 could constitute a risk to public health?
3. Consistent with the production of bovine meat and milk, what regions or departments are likely to have residues of organochlorine pesticides identified in the TOR 1?
Scope and objectives Endosulfán
