Food and Drug Administration Pesticide Residue Monitoring of Foods: 1983-1986

Pesticide residues in foods are reported for the 5-year period 1978-1982 [fiscal years (FY) 78-82]. Results were compiled from the 2 complementary elements that comprise the Food and Drug Administration's (FDA) program for monitoring pesticide residues in foods. Under regulatory monitoring, which focuses on residues in raw agricultural commodities, a total of 49,877 samples (30,361 domestic and 19,516 import) that included fresh fruits and vegetables, grains, milk and dairy products, seafoods, and a variety of processed foods were analyzed. No residues were found in about 55 and 44% of the domestic and import samples, respectively. About 3% of the domestic and 7% of the import samples were classed as violative. Data from the Total Diet Study, which is conducted to determine dietary intakes of a variety of chemicals, showed that residues of 42 pesticides were found in 1044 composites of table-ready foods. Results of FDA's monitoring for FY78-82 demonstrate that pesticide residue levels in the U.S. food supply were generally well below regulatory limits, and dietary intakes were manyfold lower than the Acceptable Daily Intakes established by international agencies.

The U.S. Food and Drug Administration uses 3 approaches to monitor pesticide residues in foods: regulatory monitoring, incidence/level monitoring, and the Total Diet Study. The results of monitoring infant foods and adult foods that may be eaten by infants/children under these 3 approaches are presented. Under regulatory monitoring, which is performed to enforce tolerances set by the U.S. Environmental Protection Agency (EPA), during fiscal years 1985-1991, over 10,000 such domestic and imported food samples were collected and analyzed, and under the Total Diet Study, in which pesticide residue intakes are estimated in foods prepared for consumption, the food items in 27 market baskets were analyzed. Under incidence/level monitoring, which is complementary to regulatory monitoring, over 4000 analyses were performed on infant foods and adult foods eaten by children. Fewer than 50 of the 10,000 regulatory samples had violative residues; nearly all of those were residues for which there was no tolerance for the particular commodity/pesticide combination. Under incidence/level monitoring and the Total Diet Study, the levels of pesticide residues found in infant foods and adult foods eaten by children were well below tolerances set by EPA.

The Food and Drug Administration (FDA) is responsible for enforcing tolerances established by the Environmental Protection Agency for pesticide residues in foods shipped in interstate commerce. FDA also determines dietary intakes of pesticides through the Total Diet Study, in which foods are collected at retail nationwide, prepared for consumption, and analyzed for residues. These different but complementary approaches have provided information over the years that demonstrates the safety of the food supply when compared with safety standards established by the federal government and international organizations. In Fiscal Year 1988, no residues were found in 61% of the more than 18,000 samples analyzed, and findings from the Total Diet Study corroborate results from previous years about the low levels of pesticide residues present in foods as consumed. Important recent initiatives deal with improving residue analytical capability, intelligence in pesticide usage, and sampling approaches. Since there is some public perception that pesticide residues in foods constitute a significant health risk, attention also needs to be directed toward this issue.

Dietary risk assessment of organophosphate and carbamate pesticide residues in commonly eaten food crops.

Organophosphate (OP) pesticides are used globally today, to control a wide range of insect pest species in agriculture, homes, and gardens, as well as in veterinary practice. OP pesticide residues in crops, food and food by-products are both a health and international trade issue. At present, QuECHER, matrix solid phase dispersion (MSPD), gel permeation chromatography (GPC), SPE, GC-FPD, GC-NPD, GC-MS, HPLC-MS, and other methods are widely used to detect OP pesticides residue in food. New issues at China Agricultural University (CAU) such as molecular imprinting, matrix effects, storage stabilities and chiral separation of OP pesticides are addressed in this article.

The present report is based on data from the 2010 EFSA Report on pesticide residues in food, the Norwegian monitoring programmes 2007-2012 and data from peer reviewed literature and governmental agencies. It is a challenge to perform quantitative estimates and comparative studies of residue levels due to large variation in the measured levels, and the large number of different pesticides present in the samples. Thus, the focus is on the frequency of observed contaminations in relation to regulatory limits and to present examples to illustrate the variation in residue values and number of detected substances. 
 Pesticide residues in conventional and organic products:
 Of the 12,168 samples (plant- and animal products) in the 2010 EU-coordinated programme, 1.6% exceeded the respective maximum residue level (MRL) values, and 47.7% had measurable residues above the limit of quantification (LOQ), but below or at the MRL. Of the 1168 samples analysed in Norway in 2012 (from both imported and domestic products), 1.9% exceeded MRL and 53% contained measurable pesticide residues. Direct comparison of these values is however not possible, since they contain different types of food samples, and are analysed for a different number of pesticides.
 When organic and conventional samples from fruit, vegetables and other plant products in the 2010 EU-coordinated programme were compared, 4.2% of the conventional and 1.0% of the organic samples exceeded the MRL values, while 43.2% of the conventional and 10.8% of the organic samples had measurable residues below or at the MRL value. Most of the pesticide residues detected in organic samples are not permitted for use in organic farming. 
 Of the 624 organic samples analysed in Norway 2007 - 2012, 0.2% (one sample) had residues exceeding MRL, while measurable residues were detected in 1.8% of the samples (11 samples).
 Conventional products were often found to contain different pesticides while most organic samples were found to contain few or only one type of pesticide. 
 Lack of data on pesticide residue levels of organic samples in the EU-coordinated programme, and few Norwegian samples do not allow for a quantitative comparison of pesticide residue levels in organic and conventional samples. Comparative estimation of pesticide residues faces a number of challenges and uncertainties. However, it seems unquestionable based on available data that organic plant products contain fewer and substantially lower amounts of pesticide residues than conventional products.
 Health risk associated with pesticide residues:
 The general level of pesticide residues in both conventional and organic food is low, and well below what is likely to result in adverse health effects. This conclusion is based on the comparison of estimated dietary exposure with toxicological reference values i.e. acceptable daily intake (ADI) for chronic effects, and acute reference dose (ARfD) for acute effects. The finding of pesticide residues that exceeds established regulatory limits in a minority of tested samples is not considered to represent a health risk.
 When dietary exposure that was estimated in six different food commodities in the 2010 EUcoordinated programme was compared with their relevant reference values, EFSA concluded that for 79 of 18243 conventionally grown fruit and vegetable samples, a short-term acute consumer health risk could not be excluded. The conclusion was based on the exceeding of ARfD. None of these 79 samples were organic. It is important to also consider that the exceeding of the acute reference value only occurred in 0.4% of the samples and that the scenario used for acute intake assessment is conservative, suggesting that the toxicological implications are limited. This is also reflected in the chronic exposure assessment, where none of the samples were found to exceed the toxicological reference value ADI. 
 Dietary exposure assessments on the basis of Norwegian samples of apples, tomatoes, carrots, strawberries and lettuce did not show an exceeding of any toxicological reference value. 
 Combined exposure and cumulative risk assessment of pesticide residues:
 No generally accepted methodology is at present established for cumulative risk assessment of combined exposure to pesticide residues. Available data suggest however that combined exposure is not likely to result in increased human health risk.

RESUMOO objetivo deste estudo descritivo e exploratório, de base qualitativa, foi identificar as resoluções do MERCOSUL sobre resíduos de agrotóxicos em alimentos publicadas entre 1991 e 2022, analisando os processos de harmonização regional desses marcos e sua incorporação ao arcabouço regulatório dos Estados Partes fundadores do bloco (Argentina, Brasil, Paraguai e Uruguai). A análise identificou pontos importantes para a regulação e o monitoramento de resíduos de agrotóxicos em alimentos no MERCOSUL, como as sinonímias utilizadas na definição de agrotóxicos e a abrangência do sistema regulatório de cada país, as marcadas diferenças no alcance dos principais marcos regulatórios nacionais, a incorporação desigual de regulamentos internacionais e regionais pelos Estados Partes e os desafios para a harmonização da legislação sobre resíduos de agrotóxicos em alimentos no âmbito do MERCOSUL. Para além dos limitados avanços observados na tentativa de harmonizar a legislação pertinente dentro do bloco, observa-se a necessidade de avançar, nacional e regionalmente, nos processos regulatórios sobre resíduos de agrotóxicos em alimentos, garantindo a qualidade dos produtos e serviços ofertados à população e fortalecendo, assim, um comércio de alimentos mais seguros e produzidos a partir de processos menos prejudiciais ao ambiente no MERCOSUL.
