Which Fruits and Vegetables Have the Most Pesticide Residue?

They’re known as the “Dirty Dozen,” and they are, in order:

  • apples
  • strawberries
  • grapes
  • celery
  • peaches
  • spinach
  • sweet Bell Peppers
  • nectarines (imported)
  • cucumbers
  • cherry tomatoes
  • snap peas (imported)
  • potatoes

This year, the EWG found that every sample of imported nectarines and 99 percent of apple samples tested positive for at least one pesticide. The average potato contained more pesticides by weight than any other food. One grape sample contained 15 pesticides, while individual samples of celery, cherry tomatoes, imported snap peas, and strawberries contained 13 different pesticides apiece.

For the third year, the EWG expanded the Dirty Dozen list with an additional category, which included kale, collard greens, and hot peppers. They don’t meet the criteria to be in the Dirty Dozen, but they still contain insecticides that can be toxic to the human nervous system. (As a result, the EWG recommends that people who often eat these foods purchase organic versions.)

Why Do Apples, Strawberries, and Grapes Have the Most Residue?

Sharon Palmer, R.D., a dietitian and nutritionist from California and the author of The Plant-Powered Diet, said that some fruits and vegetables, especially those that are eaten with the outer skin on, tend to carry more residue.

Are these foods unsafe to eat? No, Palmer said. Consumers can eliminate pesticide residue by effectively washing their produce. Some people argue that the pesticides are there but aren’t harmful to the human body—a notion that other experts completely disagree with.

Which Fruits and Vegetables Have the Least Residue?

The EWG’s “Clean Fifteen” list for 2014—foods with the lowest amounts of pesticide residue—includes avocados, sweet corn, pineapples, cabbage, frozen sweet peas, onions, asparagus, mangoes, papayas, kiwis, eggplant, grapefruit, cantaloupe, cauliflower, and sweet potatoes.

How Can Eating Pesticide Residue Harm Human Health?

Palmer explained that pesticides are used to disrupt the life cycle of insects and fungi so that they do not damage food crops.

“Although the Environmental Protection Agency establishes maximum pesticide residue levels to make sure they are below safety standards, safety concerns exist,” she said, adding that the safety thresholds are based on exposure to a single pesticide, though some foods show evidence of exposure to multiple pesticides.

“Even very small doses of some pesticides may have strong effects, especially among children, pregnant women, nursing women, the elderly, and agricultural workers,” Palmer said.

Scientists are calling for more research on the effects of pesticides, which may include brain and nervous system disorders, cancer, reproductive problems, birth defects, metabolic effects, immune system disorders, and more, Palmer added.

Does My Buying Organic food Risk of Ingesting Pesticide Residue?

It does, according to Palmer.

“Eating organic foods reduces the number of pesticides you are exposed to, because most synthetic pesticides may not be used on these crops,” she added.

Jessica Fishman Levinson, a dietitian and nutrition consultant based in New York, agrees. She says she always tells people that they should purchase organic varieties of produce on the EWG’s Dirty Dozen list.

How Can I Get Rid of Pesticide Residue?

Wash your produce—and wash it well. After washing, pat it dry to remove any excess dirt.

“It’s better to eat conventional produce than to skip it altogether,” said Fishman Levinson.

4Statement on the risks for public health related to a possible increase of the maximum level of deoxynivalenol for certain semi-processed cereal products,
EFSA Journal 2013, 11(12): 3490.
The European Food Safety Authority (EFSA) has issued a statement indicating that raising the maximum level (ML) of deoxynivalenol (DON) for selected cereal products from 750 μg/kg to 1,000 μg/kg would increase the incidence of DON exposure that exceeds current health based guidance values (HBGVs).
Although the Joint FAO/WHO Expert Committee on Food Additives (JECFA) included DON’s acetyl-derivatives in these HBGVs, EFSA’s statement provides exposure estimates for the parent compound only. As EFSA noted, occurrence data on the acetyl-derivatives are scarce and neither the current nor the proposed ML includes them.
EFSA’s data on DON occurrence in food comprised the results of DON analysis of 10,757 samples collected in 21 European countries between 2007 and 2012. Because no test results from food processors’ self-monitoring programs were available, the percentage of DON levels greater than 750 μg/kg found in products that were kept off the market could not be determined. Consequently, a simulation approach was used to predict the effect of raising the ML on mean DON levels in three cereal products (barley and wheat flour and wheat semolina). This approach entailed re-sampling their data under the constraint that the proportion of noncompliant levels would remain the same after the ML increased.
EFSA analysis indicated that the higher ML would increase mean levels of DON by a factor of 1.14 to 1.16. Based on median chronic exposures in several age classes, EFSA predicted that increasing the ML would approximately double the percentage of consumers whose exposure to DON exceeds JECFA’s group provisional maximum tolerable daily intake (PMTDI) of 1 μg/kg body weight (b.w.) for DON and its 3- and 5-acetyl derivatives.
The researchers also analyzed the effects of the higher ML in a series of acute exposure scenarios. In several of these, the resulting dietary exposures exceeded the group acute reference dose (ARfD) of 8 μg/kg b.w. established by JECFA. One scenario indicated that for individuals with the highest exposure levels, the ARfD would be exceeded on up to 25.9 percent of consumption days.
EFSA noted that higher ML can be expected to increase the occurrence of not only DON but also its acetyl-derivatives. Based on their review of relevant literature, they also concluded that acetyl-derivatives can be significant contributors to total DON exposure. In light of these concerns, EFSA called for the collection of reliable data on the occurrence of DON’s acetyl-derivatives to assess their impact on the possible health risks of the proposed ML.
The complete statement can be downloaded from the following website:
4Commission Regulation (EU) No. 212/2014 amending Regulation (EC) No. 1881/2006 to include a 2 mg/kg maximum level for citrinin in red yeast rice supplements went into effect on April 1, 2014. The new regulation reflects concerns about the risk of kidney damage in consumers who take these supplements for their cholesterol-lowering effect. According to current scientific opinion, it’s necessary to consume 10 mg of monacolin K from red yeast rice preparations daily to lower cholesterol. Consumers would have to take four to six 600 mg capsules of red yeast rice to get this amount of monacolin K. Some strains of the yeast that produces monacolin K also produce citrinin. Furthermore current data on citrinin occurrence confirms high levels in certain red yeast rice preparations. Based on these facts, the European Commission concluded that taking the recommended dose of monacolin K could expose consumers to doses of citrinin that significantly exceed the level of no concern for nephrotoxicity (0.2 μg/kg b.w. per day). The Commission will review the new ML within two years, when more data on citrinin’s genotoxicity and carcinogenicity and on citrinin exposure from other foodstuffs have been collected.

4Discussions on various mycotoxin control measures took place at the Eighth Session of the Codex Alimentarius Committee on Contaminants in Food (CCCF), which met in The Hague, the Netherlands, from March 31 to April 4, 2014. The EU delegates’ comments on these talks included requests for clarification on several points in the proposed draft MLs for fumonisins in maize and maize products. In a discussion of deoxynivalenol (DON) regulations, they agreed to a 2 mg/kg maximum level for raw wheat, maize, and barley before sorting and removal of damaged kernels. However, they objected to the proposed 1 mg/kg ML for flour, semolina, meal, and flakes made from wheat, barley, or maize and stipulated that the proposed 0.2 mg/kg ML for cereal based foods for infants and young children should apply only to cereals in their dry state. The meetings also prompted the following recommendations from the EU:
 The aggregate sample weight for wheat, barley, and raw maize subject to DON testing and for maize subject to fumonisin testing should be 10 kg; 5 kg would be an acceptable compromise.
 The proposed draft annex for the prevention and reduction of aflatoxins and ochratoxin A contamination in sorghum should be forwarded to the 37th Session of Codex for adoption.
 More data on aflatoxin occurrence in rice should be collected for a discussion of possible regulations; work should begin on a code of practice for the prevention and reduction of aflatoxins in rice.
 The discussion paper on the possible revision of the Code of Practice for the Prevention and Reduction of Mycotoxin Contamination in Cereals, the proposal for new work on a code of practice for the prevention and reduction of ochratoxin A in paprika, and the discussion paper on the establishment of a maximum level for total aflatoxins in ready-to-eat peanuts and associated sampling plan should be forwarded to the 37th Session of Codex for acceptance as new work.
 Background information on the proposal for new work on the establishment of maximum levels for aflatoxins in spices and the proposal for new work on the establishment of maximum levels for aflatoxin B1 and total aflatoxins in nutmeg and associated sampling plan should be combined in a single discussion paper.
 The Committee should wait to consider extending the proposed MLs for DON to include the acetylated DON derivatives until more occurrence data are available.

The Code of Practice for the Prevention and Reduction of Ochratoxin A Contamination in Cocoa (CAC/RCP 72-2013) was adopted at the 36th Session of the Codex Alimentarius Commission (CAC) held in Rome from July 1 to July 5, 2013. The Code recommends practices for reducing contamination during the pre-harvest stage, harvest, storage of fruits and pod opening, fermentation and drying of beans, and storage and transportation of dried beans to local industries and foreign ports.

4″Development and Evaluation of Monoclonal Antibodies for the Glucoside of T-2 Toxin (T2-Glc),” Chris M. Maragos, Cletus Kurtzman, Mark Busman, et al., Toxins, 2013, 5(7): 1299–1313.
The authors developed an innovative method for simultaneously detecting T-2 toxin and its glucoside derivative, the masked mycotoxin T2-Glc. To produce antibodies for their study, the researchers injected mice with T2-Glc that had been linked to the immune potentiator keyhole limpet hemocyanin. Cells from the immunized mice were then used to develop hybridoma cell lines. Most of the monoclonal antibodies (mAbs) showed high cross-reactivity to T-2 toxin. Cross-reactivity to HT-2 toxin was somewhat lower.
The mAbs generated by these cell lines were incorporated into immunoassays that detected T2-Glc and T-2 toxin with midpoints of inhibition curves (IC50s) in the low ng/mL range. The authors concluded that the in-depth cross-reactivity and high solvent tolerance of one of the clones, mAb 2-13, would make it particularly useful for simultaneous detection of T-2 toxin and T2-Glc.

performance Liquid Chromatography/Photodiode-Array Detector and Immunoaffinity Column Cleanup,” M. Pascale, G. Panzarini, S. Powers, and A. Visconti, Food Analytical Methods, 2014, 7(3): 555–562.
This article describes the development of the first method to use UltraPerformance Liquid Chromatography (UPLC®) combined with immunoaffinity column cleanup to simultaneously determine deoxynivalenol (DON) and nivalenol (NIV) in wheat. Mean recoveries from blank wheat samples spiked with 100–2,000 μg/kg of DON and 100–2,000 μg/kg of NIV ranged from 85 to 95 percent for DON and from 81 to 88 percent for NIV with relative standard deviations less than 7 percent. The limit of detection (LOD) was 30 μg/kg for DON and 20 μg/kg for NIV (signal-to-noise ratio 3:1). The range of applicability of the method was between the LOD and 4,000 μg/kg, as a single mycotoxin or the sum of DON and NIV in wheat.

PACA Platform meeting holds October 2014 at Adis Ababa

The First Partnership for Aflatoxin Control in Africa (PACA) Partnership Platform Meeting which is scheduled to take place from 07-09 October 2014, at the headquarters of the African Union Commission in Addis Ababa, Ethiopia. This first PACA PPM is of particular importance as it is organized in the year 2014, which was declared, by the African Union Assembly of Heads of State and Government, as the “Year of Agriculture and Food Security in Africa”.

The Partnership for Aflatoxin Control in Africa (PACA) is an innovative consortium that aims to coordinating and supporting aflatoxin mitigation and management across the health, agriculture and trade sectors in Africa. The first PACA PPM will create a forum for the full array of stakeholders involved in the management of aflatoxins – including AUC, RECs, nation al governments, private sector, health organizations, regulators, civil society groups, and development partners – to:

  1. Embrace the refined PACA Mid-Term Strategic Plan as a driving instrument for attainment of results and impact;
  2. Share implementation progress, challenges and receive input from stakeholders to enhance the effectiveness of PACA’s current activities;
  3. Exchange information, share experiences and lessons in aflatoxin mitigation and management, including evidence from recent studies;
  4. Identify and deepen partnerships to create synergies and strengthen programs aligned with the PACA Strategy and Mid-Term Strategic Plan; and
  5. Engage all stakeholders to support all efforts in the fight against aflatoxins on the African continent.

We are expecting a highly interactive meeting that will help catalyze and inform actions to help achieve PACA’s vision of an Africa free from the harmful effects of aflatoxin. There are no charges to attend the Forum.

Mycotoxins and Your Meal 2

2. Ochratoxin A

Ochratoxins are a group of chemically related mycotoxins commonly found in diverse food items like grains, coffee, cocoa, tubers, dried fruits, wine, beer and animal based meals meals As mycotoxins they are poisons produced by moulds on food, particularly in unhygienic regime. Ochratoxin A or OTA is the most important and toxic member of the family. OTA was first, in 1965 isolated from Aspergillus ochraceus, a fungus. However, as a result of contemporary advances in molecular studies, this fungus from which OTA was originally isolated was later identified as Aspergillus westerdjikiae. That was in the year 2004. Another fungal species known to produce OTA is Penicillium. The importance of this mycotoxin lies in its impact on health and export. And like most mycotoxins, OTA is associated with climatic and economic challenge. Exposure to dietary OTA in animal may result in ochratoxicosis, expressing as cancer of the kidney. In fact it has been classified as group 2B carcinogen by the International Agency for Research on Cancer IARC , meaning that it is a possible carcinogen for humans .The IARC is an arm of the WHO.

The FAO/Who publication of 2001 revealed that the Joint Expert Committee on Food Additives (JECFA) established a provisional tolerable weekly intake (PTWI) of 100 ng/kg body weight based on the lower amount of the toxin that caused adverse effects to swine kidneys . J L Schaler has reported that male and female Fischer rats given oral doses of OTA had dose- related increase in kidney tumors: renal-cell adenomas, and renal-cell adeno-carcinomas. With metastasis of the renal cell tumors. It also has an adverse effect on the the body weight, feed intake, and feed conversion in broiler chicken

Humans: Balkan endemic neuropathy (BEN) associated with OTA occurs in countries like Bulgaria, Croatia, Turkey, Egypt, and Yugoslavia where OTA is relatively high in the diet. Individuals with BEN were surveyed for the presence of urinary tract tumors. The incidence of tumors in the urinary system was elevated in both men and women. The poison damages the foetus and the DNA The major source of OTA in the diet in Europe are cereals and wine. Coffee was thought to be important in this respect, but is now considered less significant. Researchers in a few Nigerian Universities and at the Cocoa Research Institute of Nigeria have worked on the incidence of ochratoxin on coffee

Like all mycotoxins, setting of standard that are allowable in meals is based on toxicological, occurrence, distribution and epidemiological data . Some European countries have set limits ranging from 2-10 microgram per kilogram in cereals ,roasted coffee, wine and grape juice. Although Nigeria now adopts EU standards for available regulated mycotoxins, enforcement on OTA limits in food and feed are fairly lax . The Standards Organization of Nigeria is saddled with setting and monitoring standards . However this mandate is expected to be carried out in complimentary ways with the efforts of the NAFDAC, Nigerian Agricultural Quarantine Service, Nigerian Export Promotion Council, and Consumer Protection Council. On the global scale, the World Trade Organisation (WTO) Agreements on Sanitary and Phytosanitary Measures (SPS) and Technical Barriers to Trade (TBT), promote greater harmonization and transparency in the establishment of food regulations that protect the consumer and facilitate trade.

It is relatively heat stable and so can survive cooking processes. Processing like roasting and baking may lead to a slight reduction in levels. On the field, ensuring that crops are harvested at a safe moisture level is a sure preventive measure. Safe moisture prevents mould growth and so OTA production. Rapid and effective drying, ruling out insect invasion and avoidance of damage resulting in wounds as well as physical separation are also effective postharvest strategies

Mycotoxins and Your Meal

1 Aflatoxins

As humanity grows on daily basis, there is another group of small creatures called fungi, which are ubiquitous and most of which cannot be seen with unaided eyes. The Nigerian climate support the growth of this group and the subsequent production of chemicals on food items in farm, transit and store. These chemicals are toxic and are referred to as fungal toxins or mycotoxins. These toxic chemical s are found as contaminants of many items including maize, wheat, beans, groundnut, milk and milk products, yam, cassava. It is instructive that toxin production is predicated on mould growth. Nearly a quarter of the global crops are affected by them and their consumption as dietary chemicals by man and livestock incites a range of morbidities and on few occasions, mortality. Four divisions are very important because of their potency and increased research attention and, therefore health and international trade impacts. These are aflatoxins, ochratoxins, patulin and trichothecenes . Let’s start with the first one aflatoxins. This is a group that harbours the only known toxin of biological origin that has been so recognized by the International Agency for Research on Cancer, IARC. In the late 80s the Agency that serves as a technical arm of the WHO, officially placed aflatoxin B1 on the list of Type A carcinogen. The interpretation of this classification is that aflatoxin can incite cancer in human. Indeed cases of aflatoxin-induced liver cancer and immune suppression have been reported in livestock and man. High temperature, humidity and economic challenge all combine to present a formidable predisposing package. The producing fungus, Aspergillus flavus , is very common in Nigerian soil. On stale food items, it occurs as green coating , with the toxin representing a product of its secondary metabolism. This metabolite, which is colourless , odourless and tasteless, comes as B and G both representing the dietary forms and M being the one found in milk. Washing of the mouldy crop food will not remove the already secreted contaminating poison. It is heat stable so all forms of boiling may not provide any intervention. The temperature adequate to destroy it is equally sufficient the food item, so there will not be any net gain using heat to treat aflatoxin-contaminated food item. National , Continental and global bodies have been formed to address arising alimentary and export concerns.

The Mycotoxicology Society of Nigeria , Partnership for Aflatoxin   Control in Africa , PACA and the International Society for Mycotoxicology are various initiatives put in place to recommend and possibly implement interventions. At present, The MSN has its secretariat at NAFDAC, Lagos where it attends to public enquiries from the food and livestock industries.

Lessons from Ekiti election

That Fayose has won Ekiti governorship election is no longer in doubt. Even the incumbent Fayemi has admitted that. Now lets review  afew  lessons

1    Articles in Newspapers don’t win elections, the Politian himself does. Otherwise with the regular columns in a newspaper s openly sympathetic to the Fayemi, it would have a walkover. But the writers forget that the last time such outing was made in National Concord, everybody knew that the Concord did not win for Abiola, Abiola won for himself. Having  an ability to cut through barriers, religious and ethnic with a knife-in -butter ease, kit was clear MKO was indeed the one to beat.. Therefore for the Presidential election still coming in 2015, more of attacks on the President should be done on pages of newspapers, because it may not yield the desired result. Let each candidate come out and identify with the jobless, the hopeless, and the  frustrated.

2     Activism is different from political astuteness. This is why  the Nobel laureate may not win an election in his place of birth even when it is clear that he has all the ideas. When Fayemi focussed on the elderly by giving them monthly stipends, Fayose aligned with youth who are unemployed and promised the gainful employment. Whether the promise is achievable is a topic  for  another   day. Remember, the elderly are few in n umber and had no capacity to mobilise due to obvious old age, while the youth are more in number and having the energy to  move and mobilize. Again, sometimes reality   and hard facts can be counterproductive when communicated to the hungry. Ekiti is a state of teachers and civil servants. It is the height of political foolishness to denial them the simple rights they used to enjoy. Panicky appeasing measures , few days to   election would not fly.. Another bitter issue in the south west is the belief that all contracts awarded in Ekiti, Osun, Oyo, Ogun and Edo are been vetted and captured by a man in Bourdillon. The residents of these states which are collectively poorer than Lagos expected rightly that these contracts belong to them. This                 ‘Ajel e syndrome ‘  is another sour point  which is critical to the election in Osun coming in few days time.

Corruption and terrorism in Nigeria

Faces of corruption

 Over the years, illegal imports of items including arms have been going on with govt officials turning away  their  eyes. The direct  result is what we are now witnessing—-thuggery, robberies, Book Haram, kidnappings

The youth of the country with no  means of livelihood are no results to  crime, some cool eg cyber others violent eg robberies. Also there have been cases of unresolved family violence between father and son, mother and son and husband and wife


All unemployed youth should register and  get  employed  as state intelligence network officer. At the same time, all illegal small arms should be turned in within a deadline after which holders become liable to prosecution . People who give credible information on corruption and arms should be rewarded with promotions and appointments not cash.  Elected offices should provide such employment  to the youth as they would give their own children.

Human rights lawyer Ondo state born Bamidele  Aturu died on Wednesday 9 2014,  at the age of 49. Mr Aturu attended Adeyemi College of Education , Ondo after which he proceeded to the mandatory NYSC where he hit the limelight by rejecting an award . His activism  at Ondo  resulted in brushes with authorities. He proceeded to read law at the Obafemi  Awolowo University, Ile Ife. It was a profession he thought could give him the latitude to fight for the people and air his views on contemporary issues at all times. A few weeks ago , he hosted the Lagos branch of Adeyemi College of Education old students association at his office at Cement bus stop off Lagos Abeokuta expressway.

May his soul rest in peace
