"crops" news and stories

Rice is a crop that needs a lot of water to grow successfully, but too much water can be devastating, and as rice fields are usually in very low-lying lands, a flood can mean the difference between feast and famine in some parts of the world. Researchers at the University of California, Davis, in collaboration with UC Riverside and the International Rice Research Institute in the Philippines, are breeding a type of rice plant that can survive - and thrive - under water for up to two weeks, which is far longer than the three or so days that the plants generally last.

The gene that is responsible for the this submerged survival has been known or about fifty years, but it has only been in the past decade that scientists were able to isolate it and figure out how it worked. One of the primary goals is to bring the rice into areas that are at high risk of flash flooding, particularly in rural areas in Asia where the population could be devastated by a ruined crop. Another main goal is to take advantage of the ability to keep crops underwater for extended periods of time to keep weeds under control without increasing the use of pesticides or herbicides on the crops. This reduction in the use of potentially harmful chemicals could result in cleaner water supplies as the floodwaters run off the fields, less expensive rice production and higher yields. The new strain will also appeal to organic farmers, who will be able to reap the same weed-reducing benefits.

In addition to the recalls on California-grown spinach and lettuce on recent weeks, there have also been three cases of botulism liked to carrot juice produced in California, two in Canada and one in the US. It may seem as though the golden state is a hotbed of disreputable produce, but in fact so much is grown in the state that these incidents should hardly be enough to provoke widespread panic.

As much as 80% of Canadian produce, and a huge amount of US produce, comes from California and, though these few cases are certainly discouraging, the vast majority of it is fine. Companies are working to eliminate the possibility of E.coli contamination in their processing centers. Botulism is from a naturally occurring organism found in soil and, with most produce, processing should eliminate any and all traces of it from food. Raw vegetables, particularly "sugary, root vegetables " like carrots, still carry a risk factor, which is how it got in to the carrot juice in the first place.

Trying for locally grown products can provide some piece of mind, but local farmers can have the same problems, for example, by potentially exposing their crops to E.coli by using manure as fertilizer. To reduce any risks as much as possible, especially when there has been a recall of any kind, wash everything as well as you can and, if seriously in doubt, you can always cook you vegetables instead of eating them raw, which will increase the chances of killing off anything undesirable that might be in them.

The sales of White Whole Wheat Flour have increased dramatically this year over previous years and as consumer interest has grown, so have supplies. More grocery stores, large and small, now carry the flour. While the product is not new, having been available for more than a decade, its sale is no longer limited to specialty stores and it is far more widely available than ever before. This increased availability means that more people are exposed to it but many are still unfamiliar with the product.

White whole wheat flour is made from a naturally occurring albino variety of wheat. The wheat does not have the tannins or phenolic acid that are found in the outer bran of ordinary red wheat, so not only does it lack the color, but it does not any of the slightly bitter taste that is often associated with whole wheat flour. The flavor is mild and sweet, very similar to that out plain or all-purpose flour, though it does have a hint of the nuttiness of whole wheat.

A report was issued this week by the auditor of the US Department of Agriculture revealing the department's failure to properly control and regulate the trials of genetically modified crops. "In many cases, the report said, regulators didn't even know where the field trials were." Numerous violations were noted, such as not inspecting sites and failing to ensure that the trial crops with genetically modified genes were destroyed after the test was complete. This increases the risk that these genes may have been released into the environment. 

The release of the report followed the announcement that two of Monsanto Company's engineered corn traits had received final clearance from the USDA. One of the corn traits protects from a pest know as rootworm, as well as providing weed control around the crops, while the other trait combines the first with protection against a corn borer pest. Receiving final clearance for deregulation means that Monsanto can now market its products at state level and in foreign markets

The European Union has developed a proposal to allow foods that have up to 0.9% genetically modified material to be sold with labels that confirm them as organic. The EU says that this measure, which would go into effect by 2009, is being proposed to protect organic farmers against the "risk of GM contamination." The commissioner for agriculture and rural development claimed that this move would make it easier for consumers to identify organic products, presumably by making them more similar to non-organic items.

Current guidelines stipulate that organic products cannot contain genetically modified substances "in any quantity." Environmental and organic groups are protesting the action, saying that "organic" labeled products should contain no more than 0.1% GM material, the lowest amount that can be detected both reliably and consistently. The EU should support organic farming, but not by lowering the standards of the industry.
