While we are on the subject of hidden grocery store ingredients here's an excerpt about the chlorine used to wash carrots and other vegetables in the supermarket. It's from the website www.carrotmuseum.com. There are a lot of other websites out there that contain this info as well.
After harvesting, the carrots are mainly washed in chlorinated water, just like our drinking water, and cleaned to remove dirt and mud. Some finished baby carrots are washed, or dipped, by a further chlorine solution to prevent white blushing once in the store. There is no evidence that this is harmful, but it is worth knowing about!. However organic growers use a citrus based non toxic solution called Citrox (The ProGarda™), the natural alternative to synthetic biocides for the decontamination of fresh produce, food and beverages. Citrox technology incorporates a truly holistic approach designed to increase the effectiveness and profitability of food and beverage production processes.
All Citrox products are made from natural extracts or naturally derived compounds. Some of them are permitted for use in organic production (e.g.: fruit & vegetable decontaminant) or certified organic (e.g.: pre-harvest treatment products). All the Citrox derivatives are completely non-toxic, non-carcinogenic, non-corrosive, and non-tainting in use. They can actually be added to foodstuffs. They are formed by the bioflavonoid extracts and a range of completely natural organic acids, this combination having highly synergistic effects in all their many applications. The ProGarda™ decontaminant range has been specifically formulated for the decontamination of fruits and vegetables. These products are viable alternatives to the use of chlorine (or other compounds or systems) for decontaminating fresh fruits and vegetables.
According to Randy Worobo, an associate professor of food microbiology at Cornell University, you need not worry. As reported in Prevention magazine, he says carrots are not preserved in bleach but rinsed in a chlorine wash that's recommended by the FDA to kill bacteria such as salmonella and E. coli. Most pre-cut produce, including frozen vegetables and fruit salad, is washed with this or similar sanitizers.
Baby Cut and Peeled Carrots are treated with chlorine. It is used as an anti-microbial treatment to control potential contamination in the finished product. Carrots that are treated with chlorine are subsequently soaked and rinsed with potable water to remove the excess chlorine before being packaged.
Sanitizers that can be used to wash or to assist in lye peeling of fruits and vegetables are regulated by the U.S. Food and Drug Administration in accordance with the Federal Food, Drug and Cosmetic Act as outlined in the Code of Federal Regulations, Title 21, Ch. 1, Section 173.315.
Chlorine is routinely used as a sanitizer in wash, spray, and flume waters used in the fresh fruit and vegetable industry. Anti-microbial activity depends on the amount of free available chlorine (as hypochlorous acid) in water that comes in contact with microbial cells. The effectiveness of chlorine in killing pathogenic microorganisms has been extensively studied."

More on the Chlorine scare
What about the chlorine? Some carrots are washed with chlorinated water. This water must have a pH (acidity) between 6.0 and 7.0. The concentration of chlorine in the water should be between 100 and 150 ppm (parts per million). The time of contact between the carrots and the chlorinated water should not exceed 5 minutes. This must be removed from the carrots by rinsing with potable water or using a centrifugal drier. According to the Canadian Food Inspection Agency, the use of chlorine as a antimicrobial treatment is a current accepted practice in the processing for all fresh cut ready-to-eat vegetables.
This ‘Chlorine’ is most likely sodium hypochlorite also known as chlorine bleach. It is used a a disinfectant and antimicrobial in many industries. It is made by reacting a sodium hydroxide solution (also know as caustic soda or lye) with elemental chlorine gas. All of these chemicals are made from sodium chloride, also known as salt. Next time do some research look up cholera if you want a glimpse of what the world was like before the wide availability of chlorine disinfection!
Like other ready-to-eat fresh vegetables, baby-cut carrots are rinsed or sprayed with very diluted chlorine to reduce the risk of bacterial contamination, and then thoroughly washed and bagged. This process is approved by the FDA and accepted by the Canadian Food Inspection Agency, with strict rules for what concentration of chlorine can be used and how long the carrots can be exposed. Chlorine is similarly used as a disinfectant in public water supplies and sometimes in poultry processing. It is toxic at high concentrations, but there is no evidence that trace amounts left on food and in water are harmful to health.
Is this dangerous? Chlorination is a well-known and well-tested way to disinfect food products. Our tap water is chlorinated as well. When you disinfect something, that means that you kill the bacteria that are present. Chlorine kills bacteria. It can also kill us, or be very bad for us. The bleach you use to clean and disinfect your toilet, contains chlorine. Do not drink it. This will kill you because it is far more concentrated than we can safely ingest. The diluted chlorine in your tap water and in your baby-carrots, presents no proven danger whatsoever. It is precisely to make the carrots safe that the chlorine is used.
As a side-note, it is interesting to know that the term "chlorine" is something of a misnomer. Chlorine, in its natural state, is a highly reactive gas that forms compounds with other products. When chlorine is added to other products, it will react virtually immediately to form compounds such as hypochlorous acid (when chlorine is added to water) and sodium hypochlorite (when chlorine is added to a sodium hydroxide solution). These compounds in turn disinfect the water. When we talk about chlorine, and even about free chlorine, these compounds are usually what we are referring to.
Note: there are certain compounds of chlorine that do cause cancer. Does chlorine cause cancer? No. While medical science is not an exact science, and we must always be vigilant, there is at present no evidence whatsoever that chlorine causes cancer or could be a facilitator for cancer. The Department of Health and Human Services (DHHS) the International Agency for Research on Cancer (IARC), and the Environmental Protection Agency (EPA) have not classified chlorine as to its human carcinogenicity.
The solution used to wash carrots is NOT the same as in swimming pools.
