Beta-agonists (β-agonists) are feed additives used in animal production (20–40 d before slaughter) to simultaneously reduce fat gain and increase the muscle mass of animals, but the residues may remain in the tissues of animals if the withdrawal period is not observed. This is a concern due to the potential adverse health effects to humans symptomized by increased heart rate, palpitations, vasodilation, and reflex tachycardia. This study described the potential risks associated with the consumption of pork with β-agonists to the Filipino pork-consuming population through the risk profiling process. Specifically, it consolidated the available information and determined the data gaps relevant to the risk profiling process, including available risk management options for β-agonist residues in pork. The study identified and characterized β-agonist as the hazard and pork as the concerned commodity. The risk was estimated through the evaluation of β-agonist residue concentrations in pork kidneys and pork meat from the National Veterinary Drug Residue Monitoring Program of the Philippine National Meat Inspection Service and the pork consumption data of the adult Filipino consuming population from the Department of Science and Technology–Food and Nutrition Research Institute in consideration of identified uncertainties, variabilities, and assumptions. The mean and maximum dietary exposures of the adult Filipino consuming population, with an assumed average body weight of Asian adults, to β-agonists in pork meat (0.0111 and 0.1478 μg/kg bw) and pork kidney (0.0166 and 0.4847 μg/ kg bw) were estimated to exceed 100% of the acceptable daily intake of clenbuterol (0–0.004 μg/kg bw). These results indicate that there is an appreciable risk to the health of the Filipino population when it comes to the consumption of pork contaminated with β-agonists.

The Fusarium fungus is known to produce fumonisin, a naturally occurring mycotoxin associated with chronic adverse health effects in animal liver and kidney, which is commonly found in corn (Zea mays L.), one of the major agricultural crops and staple foods in the Philippines. The objective of this study was to develop a profile of the potential risks associated with the consumption of corn contaminated with fumonisins B1 (FB1) and B2 (FB2). This study involved the determination of data gaps in the risk profiling process; identification, and characterization of fumonisin; estimation of the dietary exposure (DE) and risk based on identified uncertainties, variabilities, and assumptions; and determination of available risk management options for fumonisin in corn. Fumonisin levels of corn samples (n = 77) were all below the 4000 μg/kg maximum level (ML) set in the 2019 edition of the Codex General Standard for Contaminants and Toxins in Foods (Codex GSCTFF) for raw corn grains. At the 97.5th percentile consumption of corn [yellow, white, green (or sweet) corn; edible portions (corn kernels)], the calculated DE estimates of the Filipino adult (20–59 yr old) exceeded the provisional maximum tolerable daily intake (PMTDI) of 2 μg/kg bw (body weight)/d by 420.17% (maximum FB1), 194.30% (maximum FB2), and 189.81% (overall FB1 mean). Considering the assumptions made and the gathered data in this study, the estimated DE to fumonisin in corn showed an appreciable risk to health. The current ML of fumonisin in corn and corn products adopted from Codex GSCTFF may be in need to be revisited to ensure the protection of the adult Filipino consuming population.

Aflatoxin (AFL) is a naturally occurring mycotoxin produced by Aspergillus spp. and is commonly associated with peanuts (Arachis hypogaea L.), a major field legume in the Philippines. The major types of AFL are B1, B2, G1, and G2 – comprising the total aflatoxin (AFT). AFL exposure has been shown to cause both chronic and acute toxicity, with the liver as the main target organ. It is considered genotoxic and carcinogenic. The objective of this study is to establish the profile of the potential risks associated with the consumption of peanuts contaminated with aflatoxin to the Filipino consuming population. The study included [1] determination of data gaps in the risk profiling of AFL in the consumption of peanuts by the Filipino peanut-consuming population; [2] hazard identification and characterization; [3] estimation of dietary exposure (DE) and risk- based on uncertainties, variabilities, and assumptions; and [4] consolidation of available control measures and possible mitigation protocols for AFL in peanut. AFL was detected in 92% of all the peanut samples (n = 50) analyzed, with overall mean levels of 802.83 μg/kg AFT, 683.53 μg/kg AFB1, and 119.30 μg/kg AFB2 exceeding the maximum level (ML) of 15 μg/kg set by the Codex Alimentarius Commission for AFT. Considering the assumptions made and data gathered in this study, the estimated daily intakes (EDIs) of the Filipino adult (20–59 yr old) consuming population to AFT and to AFB1 in peanut – at 97.5th percentile consumption – were 1.22–6,527.18 ng/kg body weight (bw)/d and 1.22–5,574.90 ng/kg bw/d, respectively, which exceeded the recommended provisional maximum tolerable daily intake (PMTDI) of 1 ng/kg bw/d. The margins of exposure (MOE) were also generally estimated to be below 10,000, which indicates that it is a potential health concern and that it supports the need for further risk management actions.

Methylmercury (MeHg) is one of the most toxic forms of mercury (Hg) produced via methylation of its inorganic form from natural and anthropogenic sources. Fish that feed on phytoplankton, such as sardines, serve as the entry points of MeHg in the aquatic food web. Dietary exposure (DE) to MeHg leads to varying health risks such as ataxia, neurodevelopmental delays, and blindness in newborns and infants. The study aimed to develop a risk profile on the potential risk associated with the consumption of Philippine dried tamban (Sardinella lemuru) through 1) conceptualization of the risk profile, 2) review of related literature, 3) formulation of assumptions (i.e. identification of variabilities and establishment of uncertainties or data gaps), 4) exposure pathway assessment, and 5) risk characterization. The risk of MeHg was estimated using the total mercury (THg) concentrations in dried tamban samples collected from the major fishing grounds of sardines in the Philippines, consumption data of the adult Filipino consuming population, and the assumed average body weights of Asian adults. The estimated DEs ranged from 0.000043-0.008724 μg/kg bw (bodyweight)/wk, which is equivalent to about 0.003-0.545% of the provisional tolerable weekly intake (PTWI) of 1.6 μg/kg bw for MeHg established by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) in 2007. Our findings imply that dried tamban does not pose a major health risk to the adult Filipino consuming population. However, it is also essential to note that aside from dried tamban, there are other potential sources of MeHg in the diet such as other fish and seafood.

Soy sauce is one of the commonly consumed food items in the Philippines because of its vast applications as a regular sauce and a condiment in various food dishes. One method used to produce soy sauce is chemical hydrolysis that involves acid hydrolysis of vegetable protein under high temperatures, which may generate a chemical by-product called 3-monochloropropane-1,2-diol (3-MCPD). Exposure to 3-MCPD may potentially cause adverse health effects to humans such as kidney, liver, and reproductive organ failure, as well as infertility and carcinogenicity. Thus, this study aimed to establish a profile on the potential risk associated with the consumption of soy sauce with 3-MCPD in the Philippines. This study included risk profile conceptualization, literature review, and identification of uncertainties and variabilities to formulate assumptions, which were then used in the dietary exposure (DE) assessment and estimation of risk of the adult Filipino consuming population to 3-MCPD in soy sauce. Analysis showed that the soy sauce samples (n = 19) collected from identified supermarkets and wet markets in the Philippines contained 3-MCPD levels below the maximum level (ML) of 0.4 mg/kg set by the 2019 edition of the Codex General Standards for Contaminants and Toxins in Food and Feed. With these generated data on the hazard levels, the high consumer (97.5th) percentile soy sauce consumption data from the Philippine Department of Science and Technology–Food and Nutrition Research Institute (DOST-FNRI), and the assumed body weight of an adult Asian, the DE of the adult Filipino consuming population to 3-MCPD in soy sauce was estimated to be 0.0327–0.1636 µg/kg body weight (bw)/d, which was lower than 4 µg/kg bw – the latest provisional maximum tolerable daily intake (PMTDI) set by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) in 2016. Based on these findings, the consumption of soy sauce showed no appreciable risk to the health of the Filipino consuming population.
