2017 Produce Samples Survey Show Safeness For Consumers

Tests Show Low or No Pesticide Levels in Most Fruits and Vegetables in California

By Charlotte Fadipe, California DPR

Once again, tests showed that the vast majority of fresh produce collected by the California Department of Pesticide Regulation (DPR) met national pesticide residue standards. During its 2017 survey, DPR found 96 percent of all samples had no detectable pesticide residues or were below levels allowed by the U.S. EPA.

The findings are included in DPR’s just released 2017 Pesticide Residues in Fresh Produce report.

“DPR carries out an extensive sampling of pesticides on fresh produce, and once again it shows that California consumers can be confident about eating fresh fruits and vegetables,” said Brian Leahy, Director of DPR. “California growers and farmers are adept at following our comprehensive rules to ensure produce is grown to the highest pesticide standards.”

The 2017 report is based on a year-round collection of 3,695 samples of produce from 28 different countries, including those labeled as “organic.” DPR scientists sampled produce from various grocery stores, farmers’ markets, food distribution centers, and other outlets throughout California. The produce is tested for more than 400 types of pesticides using state-of-the-art equipment operated by the California Department of Food and Agriculture.

The U.S. Environmental Protection Agency (U.S. EPA) sets levels for the maximum amounts of pesticide residue that can be present on fruits and vegetables, called a “tolerance.” It is a violation if any residue exceeds the tolerance for the specific fruit or vegetable, or if a pesticide is detected for which no tolerance has been established.

California Specific Results

More than a third of the country’s fruits and vegetables are grown in California, according to the California Department of Food and Agriculture (CDFA). In 2017 DPR found:

-About 25 percent of all produce samples tested were labeled as Californian-grown,

-About 95 percent of these samples had no residues on them or were within the legal levels,

-About 5 percent of California samples had illegal residues, including kale and snow peas. These are pesticide residues in excess of the established tolerance or had illegal traces of pesticides that were not approved for that commodity. However, none of those residues were at a level that would pose a health risk to consumers.

Other highlights from the 2017 report include:

-41 percent of all produce samples had no detectable residues at all,

-55 percent had residues detected within the legal level.

-4 percent of all the samples had pesticide residues in excess of the established tolerance or had illegal traces of pesticides that were not approved for that commodity.

Pest Management is Essential

The Positives of Pest Management

By Mikenzi Meyers, Associate Editor

There’s a case to be made for both organic and conventional farming, but make no mistake that they both have the same intention: safe food for human consumption. Few people know this better than Brian Leahy, chief of the Department of Pesticide Regulation in California, one of the 16 agencies under the umbrella of the California Environmental Protection Agency.

There are certain precautions that all farmers need to take to ensure our produce is of the highest quality, one of which is the use of pesticides. Leahy explained that yes, even organic growers require pesticides to protect their crop.

“They’re very different, and they go through a process,” he further added.

“When your food leaves the farm, it goes through a lot of pest management,” Leahy continued, “We’re doing it every day, so let’s acknowledge that it’s there.”

The fact is, everyone uses pesticides, whether it be in the grocery store or our very own homes, and if they are not properly managed it can lead to trouble.

“We’re all in this pest management together. Let’s start putting the resources into it so that we do it in a way we think we want,” Leahy concluded.

Cannabis Growers Not Following Regs

Cannabis Growers Must Adhere to Crop Protection Regulations

By Patrick Cavanaugh, Farm News Director

There’s a whole lot of trouble going on for California cannabis growers. They need crop protection products for pests – such as mites, aphids, thrips, and mealybugs – and diseases, including powdery mildew, alternaria and pythium.

Now legally grown in the state, cannabis meets the definition of an agriculture crop and must adhere to all agricultural regulations and best management practices. This includes all Pest Control Advisor-written recommendations. As few products are approved for application on cannabis in the state, as well as nationwide, a PCA can now be cited for recommending a product that has not been officially registered and approved for a use on cannabis, specifically. With legal cannabis production going mainstream in California, PCAs face this risky predicament regularly.

“I discussed this point with Department of Pesticide Regulation (DPR) Director Brian Leahy this past week,” said Rachel Kubiak, DPR Pesticide Programs Division, Cannabis Program Supervisor. “I think we are at a point now where it’s important that we make policy decisions so PCAs know, as stakeholders, what our expectations are. PCAs deserve for us to do that, so we are working internally right now to try to get a lot of answers to these questions.”

Cannabis growers will have to buy products from licensed agricultural dealers.

“I understand, in talking to different folks, that many companies are not comfortable with the liability of attaining DPR registration approval for cannabis application and are therefore advising not to sell product to cannabis growers,” Kubiak said. “I completely understand that.”

“Going forward as a department, the concern, I think, is to bring as many farmers into the legal crop protection market as possible,” Kubiak said. “They are going to go exactly where they have been buying the products from, right? And if PCAs do not sell to them, but the cannabis growers must buy from them, these growers will have to purchase their crop protection products online, from Home Depot, or anyplace else. I can almost guarantee you that 95% or probably more of the cannabis farmers I’ve talked to over the last couple of months have no idea what we are talking about regarding applying registered materials to registered crops.”

“They have no idea that you cannot buy product anyplace and apply it as a pesticide,” she explained. “They do not know how to store it. So we have a lot of work to do in a very short period of time to bring these people into compliance and understanding.”

The scenario is even dicier for California County Agricultural Commissioners. These commissioners are required to enforce regulations on cannabis, as they are for any other commodity.

“We are working with the county ag commissioners to figure out how we need to proceed with and advise on this,” Kubiack said.

“I will tell you, usually as a department,” Kubiak explained, “we are inundated by the environmental justice community. Yet, they have been completely absent to this point on this particular commodity. So it’s almost bizarre and unusual not to be hit continuously from the left. But understandably, again, we’re now getting into these forums in which the Ag community has a voice and an interest,” Kubiak said.

“I’ve heard from both sides,” she continued. “I have heard from different Ag groups and PCAs who have said, ‘You know, we see a need for this—by a whole industry of people,’” she said.

And that whole industry, the cannabis growers of California, is crossing the regulatory line in crop protection. It has been reported that cannabis growers are creating a lot of environmental damage as well as worker safety concerns. Cannabis is grown primarily indoors, and according to Kubiak, “People are using pesticides without any concept of what they’re doing. Normally we would recommend that they talk to a professional, but that puts licensed PCAs in a hard spot because they cannot write a recommendation for a product that is not legally approved for use on that product.”

Kubiak said DPR is trying to bring as many of cannabis growers into the light as possible, “so that we have some regulation. Again, clearly this has been going on for a really long time, but at least now we are trying to go into areas in which we have some regulation but where people are not necessarily informed. So we bring crop protection management more into the light than ever before,” she said.

Is the DPR at a big turning point in working with county Ag commissioners?

“In the absence of putting up a product list,” Kubiak asked, “what is quasi-legal and what is not quasi-legal? We are trying to come up with solutions to some of these dilemmas.”

“There are counties that want the flexibility. Boards of supervisors and their counties are economically dependent upon this newly emerging industry that’s been in the North Coast for decades. They want the ability to use discretion. Nevertheless, Ag commissioners in other counties clearly are not comfortable with that whatsoever,” Kubiak said.

Homeowners: Your Gardeners Need License to Apply Pesticides

Homeowners Urged To Make Sure Gardeners Who Apply Pesticides Have License

The California Department of Pesticide Regulation (DPR) is urging all homeowners to check that their maintenance gardener (landscaper) has a state maintenance gardening (MG) pest control business license from DPR if they are occasionally applying pesticides on their lawns. Homeowners can do so on the DPR website’s License and Certificate Holder List Page.

“Homeowners may not realize that maintenance gardeners are applying chemistry to their lawns,” says DPR director Brian Leahy. “We want to try and ensure they are doing so in a responsible manner.”

The license ensures that the person applying pesticides has been properly trained to use them on lawns and garden areas. If used properly, pesticides should not cause harm to humans or pets. However, improper use may result in illnesses or environmental problems.

Pesticides used on lawns and gardens may be washed to street storm drains and into local rivers, streams and even sensitive wetlands miles away. This may impact aquatic life.

“Your lawn may only be a small piece of land, but collectively, California lawns amount to many acres,” said Leahy. “Homeowners can play a significant role to reduce the amount of pesticide pollution (runoff) from lawns that are entering our waters through storm drains.”

Under California law, anyone who applies pesticides, even if it is only incidental to other maintenance gardening tasks, must have this DPR maintenance gardening pest control business license and be registered with the local county agricultural commissioner’s office.

In California, there are about 100,800 landscapers employed in the public and private sector who are responsible for maintaining homes, parks, golf courses, schools and plantings around malls, offices, restaurants and other locations.
