More Facts About the “Dirty Dozen” List

New So-called “Dirty Dozen” List is Baseless

News Release

To everyone that has read about the “Dirty Dozen” list and is now confused and conflicted about buying the more affordable and accessible fruits and veggies, this blog is for you. Keep in mind that the “Dirty Dozen” list is designed to make you worry and be fearful. After all, fear is a very powerful motivator, and the list authors attempt to increase safety fears to motivate and influence consumers’ produce buying decisions.

So here are some facts about the “Dirty Dozen” list that underscore you can consume either conventional or organic produce with confidence. Both are safe, and the right choice is to eat more every day.

Arbitrary Methodology: According to Dr. Carl Winter, toxicologist, University of California, Davis.: “This year’s EWG list is produced using the same arbitrary methodology the EWG has used in the past. Most importantly, the EWG focuses upon the presence (or absence) of pesticide residues in its methodology and public statements rather than on the actual amounts of pesticides detected, which are extremely low. To accurately assess consumer risks from pesticides, one needs to consider three major factors – 1) the amount of residue on the foods, 2) the amount of food consumed, and 3) the toxicity of the pesticides. The methodology used by EWG ignores all three.”
Meet Organic Standard: Did you know that the vast majority of conventionally grown produce tested by United States Department of Agriculture could qualify to be labeled “organic,” specific to their residue levels? It’s true. The USDA allows organic produce to have residues that are “less than 5% of EPA tolerances” and the majority of residues found on conventionally grown produce are below this level. This nicely illustrates how low residues are, if present at all.
You Can Eat A Lot of Kale: If you are concerned about residues on kale, you would have to eat a lot more each day to see any health effects. In fact, a man would have to eat 26,061 servings in a day.. Click here to continue reading and to like and share this blog post.

Pests and Diseases Cause Worldwide Damage to Crops

Pests and Pathogens Place Global Burden on Major Food Crops

By Pam Kan-Rice, UC Agriculture & Natural Resources

Scientists survey crop health experts in 67 countries and find large crop losses caused by pests and diseases

Farmers know they lose crops to pests and plant diseases, but scientists have found that on a global scale, pathogens and pests are reducing crop yields for five major food crops by 10 percent to 40 percent, according to a report by a UC Agriculture and Natural Resources scientist and other members of the International Society for Plant Pathology. Wheat, rice, maize, soybean, and potato yields are reduced by pathogens and animal pests, including insects, scientists found in a global survey of crop health experts.

At a global scale, pathogens and pests are causing wheat losses of 10 percent to 28 percent, rice losses of 25 percent to 41 percent, maize losses of 20 percent to 41 percent, potato losses of 8 percent to 21 percent, and soybean losses of 11 percent to 32 percent, according to the study, published in the journal Nature, Ecology & Evolution.

Viruses and viroids, bacteria, fungi and oomycetes, nematodes, arthropods, molluscs, vertebrates, and parasitic plants are among the factors working against farmers.

Food loss

“We are losing a significant amount of food on a global scale to pests and diseases at a time when we must increase food production to feed a growing population,” said co-author Neil McRoberts, co-leader of UC ANR’s Sustainable Food Systems Strategic Initiative and Agricultural Experiment Station researcher and professor in the Department of Plant Pathology at UC Davis.

While plant diseases and pests are widely considered an important cause of crop losses, and sometimes a threat to the food supply, precise figures on these crop losses are difficult to produce.

“One reason is because pathogens and pests have co-evolved with crops over millennia in the human-made agricultural systems,” write the authors on the study’s website, globalcrophealth.org. “As a result, their effects in agriculture are very hard to disentangle from the complex web of interactions within cropping systems. Also, the sheer number and diversity of plant diseases and pests makes quantification of losses on an individual pathogen or pest basis, for each of the many cultivated crops, a daunting task.”

“We conducted a global survey of crop protection experts on the impacts of pests and plant diseases on the yields of five of the world’s most important carbohydrate staple crops and are reporting the results,” McRoberts said. “This is a major achievement and a real step forward in being able to accurately assess the impact of pests and plant diseases on crop production.”

The researchers surveyed several thousand crop health experts on five major food crops – wheat, rice, maize, soybean, and potato – in 67 countries.

“We chose these five crops since together they provide about 50 percent of the global human calorie intake,” the authors wrote on the website.

The 67 countries grow 84 percent of the global production of wheat, rice, maize, soybean and potato.

Top pests and diseases

The study identified 137 individual pathogens and pests that attack the crops, with very large variation in the amount of crop loss they caused.

For wheat, leaf rust, Fusarium head blight/scab, tritici blotch, stripe rust, spot blotch, tan spot, aphids, and powdery mildew caused losses higher than 1 percent globally.

In rice, sheath blight, stem borers, blast, brown spot, bacterial blight, leaf folder, and brown plant hopper did the most damage.

In maize, Fusarium and Gibberella stalk rots, fall armyworm, northern leaf blight, Fusarium and Gibberella ear rots, anthracnose stalk rot and southern rust caused the most loss globally.

In potatoes, late blight, brown rot, early blight, and cyst nematode did the most harm.

In soybeans, cyst nematode, white mold, soybean rust, Cercospora leaf blight, brown spot, charcoal rot, and root knot nematodes caused global losses higher than 1 percent.

Food-security “hotspots”

The study estimates the losses to individual plant diseases and pests for these crops globally, as well as in several global food-security “hotspots.” These hotspots are critical sources in the global food system: Northwest Europe, the plains of the U.S. Midwest and Southern Canada, Southern Brazil and Argentina, the Indo-Gangetic Plains of South Asia, the plains of China, Southeast Asia, and sub-Saharan Africa.

“Our results highlight differences in impacts among crop pathogens and pests and among food security hotspots,” McRoberts said. “But we also show that the highest losses appear associated with food-deficit regions with fast-growing populations, and frequently with emerging or re-emerging pests and diseases.”

“For chronic pathogens and pests, we need to redouble our efforts to deliver more efficient and sustainable management tools, such as resistant varieties,” McRoberts said. “For emerging or re-emerging pathogens and pests, urgent action is needed to contain them and generate longer term solutions.”

The website globalcrophealth.org features maps showing how many people responded to the survey across different regions of the world.

In addition to McRoberts, the research team included lead author Serge Savary, chair of the ISPP Committee on Crop Loss; epidemiologists Paul Esker at Pennsylvania State University and Sarah Pethybridge at Cornell University; Laetitia Willocquet at the French National Institute for Agricultural Research in Toulouse, France; and Andy Nelson at the University of Twente in The Netherlands.

UC Agriculture and Natural Resources researchers and educators draw on local expertise to conduct agricultural, environmental, economic, youth development and nutrition research that helps California thrive. Learn more at ucanr.edu.

Strawberry Labor Issues May be Helped

New Technology in the Strawberry Industry Addresses Labor Issues

By Mikenzi Meyers, Contributing Editor

Once again, technology has taken crop production to the next level. This time, strawberry growers are reaping the benefits of technological advancements. Pete Molero and his team at Plantel Nurseries have come up with a transplanting machine that will address labor challenges in the strawberry field.

“We have come up with a transplanting machine that uses a 25-man crew to plant strawberries that have foliage on them and have a plug just like a transplant vegetable plug now,” Molero explained.

He further added that the machine can plant an acre an hour, a pace that would typically take 80 to 100 employees to achieve.

According to Molero, the process is simple.“The plug goes in, the plant gets dirt, and its set and ready to go.”

He described the root itself as a two-and-a-half to three-inch plug with first growth leaves at about three to four inches tall. As of right now, there is only one variety of strawberry available for the summer. However, new ones are being tested in hopes that this new equipment will continue to make improvements.

Tomato Spotted Wilt Virus Fights Back

New Strain Creates Challenges

By Mikenzi Meyers, Associate Editor

A new strain of the Tomato Spotted Wilt Virus has created a challenge among vegetable growers, making integrated pest management, or IPM, increasingly critical. Bob Gilbertson, plant pathologist at UC Davis, has insight and advice as to how farmers should tackle this new strain.

“The first thing is to know what’s out in your field. And there’s a good diagnostic test for curly top, spotted wilt, alfalfa mosaic, and other viruses,” Gilbertson said.

Bob Gilbertson

After the virus is confirmed, he encourages growers to explore their options of treatment. Prior to the new spotted wilt virus strain, growers could turn to the SW-5 resistance gene to cure their field. Unfortunately, Gilbertson explained, the new strain actually breaks that resistance, which is where IPM becomes even more important.

In the future, Gilbertson hopes to find additional resistance genes to break the new strain. Until that time comes, he wants to use good IPM to manage it.

Gilbertson further added, “Increased sanitation, removing overwintering hosts, weeds, and bridge crops like lettuce, and then timing the applications of thrips management better, to slow down the appearance of adult thrips that carry the virus,” are all examples of good IPM.

Berry Industry Without Methyl Bromide

Berry Industry Must Now Work Smarter in Post Methyl Bromide Era

By Patrick Cavanaugh, Editor

The strawberry fruit production industry, with the exception of plant nurseries, has reached the point where methyl bromide is no longer available under any circumstances, and new alternatives or strategies must be found to protect strawberries from serious diseases.

The University of California is focused on a holistic approach, which includes the tried-and-true method of integrated pest management in this post Methyl Bromide era.

“None of the alternative fumigants are as good as methyl bromide,” said Mark Bolda, UC Cooperative Extension Farm Advisor for Santa Cruz County, who is working closely with growers on alternative methods. “So one area that we could focus on is different strategies at the time of planting. For example, strawberries have different chill times. You must add cold conditioning to give the plant more vigor.”

Mark Bolda

There are many questions. Could the colors of the plastic mulch that growers are using manage the temperatures of the soil? How about the amount of fertilizer that is being used?

“We need to start integrating these variables into the way we grow strawberries with the lack of fumigants that are as effective as methyl bromide,” Bolda explained. “We need to integrate all these things and others in order to grow berries with the lack of available fumigants that are as effective as methyl bromide.”

“It’s a little disappointing that here we are at zero-hour and we do not have this worked out,” he continued. “The University of California Cooperative Extension have had a number of meetings in my office, as well as other places where we get many people in the same room to try to figure out what we know and what we don’t know.”

“There’s a lot of smart people in the industry, and I know we can get on this and find solutions,” he said.

Mechanically Harvesting Broccoli

Saving Labor Cost in Broccoli Harvest

By Jessica Theisman, Associate Editor

Josh Ruiz and Monsanto Seeds have partnered up to harvest broccoli mechanically. Ruiz is vice president of AG operations with Church Brothers Farms in Salinas.

“They brought us a genetic variety of broccoli where the head does sit up higher. When it comes to broccoli, all varieties have their heads mature at different rates,” Ruiz explained.

That being said, the fields must be harvested multiple times as the crop matures. With these new genetics, you can get it all done in one sweep.

“I want it to be as simple for my people because I want them to be happy. Cutting once and moving on is what makes them happy,” Ruiz said.

There are a bunch of growers around California, Arizona and in Mexico; they want to get that ground back and use it one more time before the season’s over.

“This gives them about a month’s worth of time back in their hands, which, in the world we live in, is huge,” Ruiz said.

Ruiz said he is going to continue to develop mechanical harvesting for other crops.

“Iceberg and Romaine are the next two big projects,” he explained.

Iceberg is known to be the “holy grail.” Ruiz has a prototype in the works, and he’s willing to work with anyone who is willing to partner.

“The Broccoli Project, the last five years, has overwhelmed my team and me, but we are ready for the next challenge,” he said

“My day to day is focused on not only running the AG operations for Church Brothers, but I spend a lot of my day focused on innovation and how can we do things better, quicker, faster, cheaper,” he continued.

Ruiz is passionate about automation and innovation. He is currently working with lettuce, romaine, broccoli, cauliflower, spring mix, spinach, and kale.

He said his interest in mechanical harvesting is mostly based out of labor issues, but it goes further from there.

“I see this as the future. I’m not the computer guy, and I’m not the engineer, but I love that stuff, and I want to go find out how to make it possible for me to learn,” he said.

Approximately five years ago, Ruiz began his relations with Monsanto with the Broccoli Project.

“We just unveiled our brand new version of our machine, and I have no doubt in my mind that it’s going to be out there in the field. You’ll see it going down the Salinas Valley from here on out.”

Strawberry Commission Oversees Valuable Crop

Strawberries in California

By Jessica Theisman, Associate Editor

Strawberries are California’s sixth most valuable crop which makes strawberry research a valuable tool for California farmers. Mercy Olmsted is senior manager of production research and education at the California Strawberry Commission. Growers in the California Strawberry Commission have invested over $28 million into research. These include areas such as diseases, insects, and weeds—all in an effort to help solve production challenges and boost economic gains.

“We are a commission that’s funded by the growers, and so we do research that meets their research priorities,” Olmsted said.

So far, $13 million has been invested in research to explore alternatives to methyl bromide. The commission says that strawberry farmers continue to invest in researching fumigant alternatives.

“We also work with researchers. We have a robust grant program, and we work with those researchers in order to assist them in their field trials,” Olmsted explained.

Some of their researchers are in house, and others are from the USDA and university researchers.

“We develop training programs for our growers because we work for the growers. We can contact them as often as we need to, and we are able to see how things and research priorities might change in the industry,” Olmsted said. “There are a number of facilities and a board that helps direct research priorities and any necessary changes.”

It’s Truly a California Thanksgiving

California Growers and Ranchers Provide Nearly Everything On the Table

By Patrick Cavanaugh, Editor

It’s truly a California Thanksgiving, as most of the products come from the growers and ranchers here.

Turkeys come from several areas of the state, and while California is No. 7 in turkey production, they do supply most of the western United States.

And the famous Mrs. Cubbison’s dressing comes from a California gal, Sophie Cubbison, who as born in 1890 in the San Marcos area of San Diego County. A long interesting story made short: In May of 1920, she graduated from California Polytechnical University with a degree in Home Economics. It was 1948 when she used broken pieces of the popular Melba toast and added seasoning to make stuffing. A factory in Commerce, CA, churns it this time of year.

And farmers in California also produce almonds, walnuts, pistachios, raisins, prunes, figs, dates, apricot, and pomegranates right up the food line.

Celery comes from the Oxnard and Ventura area, and the ingredients for the stuffing mix–carrots, lot of lettuce and fresh spinach–in Salinas now that they have all these greens, already washed and bagged in the produce department. The green beans come from California growers as well. c

You’ve got oranges, kiwi fruit, colorful persimmon fruit, table grapes, strawberries, raspberries, and blueberries that have been freshly harvested from many areas of the state. You’ve got sweet potatoes from the Merced area. This is the major season for them. You’ve got all kinds and colors of potatoes and tomatoes and parsley, onions and garlic–all crops grown in California

Practically all the fruits and vegetables and nuts are part of America’s Thanksgiving, and nearly all of it comes from California. There is often a wide array of cheeses and that wonderful whip cream that comes from the California dairy industry—number one in the industry.

And don’t forget about the great variety of California wine grapes that are grown by California growers and then crafted into great California wine.

You’ve you have apples and those small round watermelons that are a great snack or dessert item as part of a fruit salad. And we have poultry, and even California lamb if you want to go that way.

And of course Martinelli Sparkling Apple or Grape cider from Watsonville. Local growers provide the tree-ripened fruit to the award-winning company, which is more than 140 years old and still family-owned and run by the founder’s grandson and a great-grandson.

In fact, it was 1890 when the company was award the first place at the California State Fair.

And by the way, you know that pop-up turkey timer that indicates when the turkey has reached the correct internal temperature? It was invented by public relations genius Leo Pearlstein, who handled promotions for the California Turkey Advisory Board for 25 years. Each Thanksgiving, hundreds of consumers would call to ask how long it takes to cook a turkey in the oven. In the 1960s, Pearlstein and a turkey producer from Turlock were sitting in a room trying to figure out the solution. They looked up and noticed the fire sprinklers in the ceiling.

Sprinkler water comes on when it is hot enough to melt a metal alloy. The same concept is used in the pop-up timer. Many turkey brands have the special pop-up timer included with them today.

With the exception of cranberries, it’s really a California Thanksgiving.

And we are grateful to all the California farmers and ranchers for providing so much for all of us this holiday and throughout the year.

FDA Releases Possible Factors for 2018 E. Coli Outbreaks

Leafy Greens Industry and Public Were Severely Impacted

By Hank Giclas, Western Growers Sr. Vice President, Strategic Planning, Science & Technology

Recently, the U.S. Food & Drug Administration released an environmental assessment that provides an overview of factors that potentially contributed to the contamination of romaine lettuce with E. coli that was implicated in a 2018 multi-state foodborne illness outbreak. The assessment can be found here and includes the background on the outbreak; the environmental team approach; and factors potentially contributing to the introduction and spread of E. coli; along with recommendations for the prevention E. coli in leafy greens.

FDA recommends that growers and processors of leafy greens:

assure that all agricultural water (water that directly contacts the harvestable portion of the crop) used by growers is safe and adequate for its intended use (including agricultural water used for application of crop protection chemicals);
assess and mitigate risks related to land uses near or adjacent to growing fields that may contaminate agricultural water or leafy greens crops directly (e.g. nearby cattle operations or dairy farms, manure or composting facility);
verify that food safety procedures, policies, and practices, including supplier controls for fresh-cut processors, are developed and consistently implemented on farms (both domestic and foreign) and in fresh-cut produce manufacturing/processing food facilities to minimize the potential for contamination and/or spread of human pathogens;
when a foodborne pathogen is identified in the growing or processing environment, in agricultural inputs (e.g., agricultural water), in raw agricultural commodities or in fresh-cut, ready-to-eat produce, a root cause analysis should be performed to determine the likely source of the contamination, if prevention measures have failed, and whether additional measures are needed to prevent a reoccurrence; and
Local in-depth knowledge and actions are critical in helping resolve potential routes of contamination of leafy greens in the Yuma growing region, including Imperial County and Yuma County, moving forward. FDA urges other government and non-government entities, produce growers and trade associations in Yuma and Imperial Counties to further explore possible source(s) and route(s) of contamination associated with the outbreak pathogen and with other foodborne pathogens of public health significance. This information is critical to developing and implementing short- and long-term remediation measures to reduce the potential for another outbreak associated with leafy greens or other fresh produce commodities.

The findings in the Environmental Assessment appear to provide little new information but will be closely reviewed by Western Growers and others as part of our industry’s ongoing efforts to ensure food safety.

Immediately after the outbreak, Western Growers collaborated with the leafy greens industry to help lead a task force that would assess the source of the outbreak, as well as develop recommendations to prevent future outbreaks. While sources of contamination remain uncertain, the task force made concrete recommendations to industry for assuring water is safe and adequate, assessing and mitigating risk from adjacent land uses as well as others to address risks from equipment and climatic conditions. These recommendations go well beyond the requirements of the FDA’s own Produce Safety Rule and have already been incorporated into the California and Arizona LGMA requirements. State auditors are now charged with verifying adherence to these new controls through announced and un-announced audits that occur throughout the seasons. The industry is furthering its efforts to learn more including through research guided by respected entities such as the Center for Produce Safety and working directly with California and Arizona academic teams. There is a strong and broad commitment to continually work to improve our food safety system.
