...Food safety is a growing concern globally. With the innovations in the processing technologies, packaging techniques, agricultural practices, and change in food habits, industry and enforcement authorities are facing new challenges every day. Currently there are more than twenty Indian laws relating to food, which are administered by a number of different Ministries and Departments. Food processors have to comply with these rules. Among the more important food laws are: • Prevention of Food Adulteration Act (PFA) of 1954 and the PFA Rules of 1955.

...Paraben Paradox Parabens are preservatives used in a variety of personal care, cosmetic, pharmaceutical, food products. Studies have confirmed the ubiquitous presence of parabens, with levels detected in wastewater, rivers, soil and house dust. Parabens have also been detected in human tissues and bodily fluids. Parabens are popular preservatives because of their low toxicity and cost, their broad inertness, and their worldwide regulatory acceptance (Soni et al. 2005). Methyl paraben (MP) and propyl paraben (PP) are two of the most used parabens (Andersen 2008). Parabens easily penetrate the skin. The European Commission on Endocrine Disruption has listed parabens as Category 1 priority substances, based on evidence that they interfere with hormone function. Parabens can mimic estrogen, the primary female sex hormone. They have been detected in human breast cancer tissues, suggesting a possible association between parabens in cosmetics and cancer. It has been estimated that women are exposed to 50 mg per day of parabens from cosmetics. However, studies investigating the health effects of parabens are conflicting. There are no restrictions on the use of parabens in cosmetics in Canada, whereas International regulations are stronger. The European Union restricts the concentration of parabens in cosmetics. Parabens are typically...

...main reason for the addition of salt to food was for preservation. Because of the emergence of refrigeration and other methods of food preservation, the need for salt as a preservative has decreased, but sodium levels, especially in processed foods, remain high. The expected tastes and flavors associated to salt use is enormous coupled with the relative low cost of enhancing the palatability of processed foods, thus making it a key rationale for salt use in food preservation. However, taste is not the only reason for the continued use of high levels of salt in foods. For some foods, sodium still plays a role in reducing the growth of pathogens and organisms that spoil products and reduce their shelf life. In other applications, sodium levels remain high because salt plays additional functional roles, such as improving texture. A number of other sodium-containing compounds are also used for increasing the safety and shelf life of foods or creating physical properties. This work begins with a review of the non-taste or flavor-related roles of salt and other sodium-containing compounds in food. The second part will briefly discuss the role that sodium plays in various food categories and provides examples of the sodium content of various foods. ------------------------------------------------- FOOD SAFETY AND PRESERVATION ------------------------------------------------- As mentioned previously, the first major addition of salt to food was for taste and to prevent spoilage...

...there usually is a negative. Not only is the process of making a hotdog rather disgusting, there may be some health risks associated with eating them. If the American public was aware of how hotdogs are produced and the ingredients used to create them, it is likely that hotdogs would not be the food of choice for many people. While there is no definitive answer on how many hotdogs are actually produced in America each year, there are some rather eye popping statistics of Americans’ infatuation with the hot dog. There are approximately nineteen billion hotdogs consumed each year (weirdfacts.com). The summer season seems to be the most popular for eating hotdogs, as a stunning seven billion hotdogs are eaten from Memorial Day to Labor Day, with 150 million of those being eaten on July 4th alone (fillyourplate.org). Another hard to believe fact about hotdogs is there are roughly 550 eaten every second (weirdfacts.com). The popularity of the hotdog is evident by the fact that it is served in 94% of homes in the United States (weirdfacts.com), and the average American will eat approximately fifty hotdogs each year (blog.fooducate.com). With the hot dog being such a popular choice of food, let’s take a look at how they are actually made. First, trimmings or unwanted cutoffs from pork, beef, and chicken are mixed together and ground into a product similar to ground beef. Liquids, such as water and corn syrup,...

...shelf-life of food especially meat products is to reduce the storage temperature; where the concept of refrigeration came up. A direct linear relationship was strongly established between temperature and bacterial growth, long decades ago, and low temperature has been confirmed to have a bacteriostatic effect (Ratkowsky et al., 1982). It has been shown that spoilage rate of poultry stored at 10 °C and 15 °C is twice and three times that of 5 °C, respectively (Jay, 2005). Anbalagan et al. (2014) have shown that the total vial count in chicken sample stored in freezers at -18 °C has decreased from 156×105 cells/gram to 35×102 cells/gram in five days.

...582 MAINE LAW REVIEW [Vol. 65:2 A NATIONAL “NATURAL” STANDARD FOR FOOD LABELING Nicole E. Negowetti * I. I NTRODUCTION What do Juicy Juice fruit punch, SunChips, Nature Valley granola bars, and Skinny Girl Margaritas have in common? These products are all branded with the term “natural.” From canned vegetables to cereals to soft drinks, the term “natural” has become one of the most common claims on foods, drugs, dietary supplements, and personal care products. The word “natural” on a label or in advertising brings to mind nature, and things that are pure, clean, healthy, 1 free of artificial additives, 2 and therefore safe, harmless, and beneficial to overall health. In 2011, “all-natural” was the second-most-used claim on new American food products. 3 The food industry’s marketing of such products has been extremely successful. In 2009, sales of products with a “natural” claim reached $22 billion, 4 and a recent study found that the “natural” claim is the most popular among consumers. When asked “which is the best description to read on a food label,” 31% of consumers selected “100% natural” and 25% selected “all natural ingredients.” 5 Although both the Food and Drug Administration (FDA) and U.S. Department of Agriculture (USDA) are statutorily mand ated to protect consumer interests by prohibiting false and misleading labeling, both agencies have refused to formally * Assistant Professor of Law, Valparaiso University Law School.

...Comparison and Contrast of Organic and Conventional Farming: An Overview of Differences and Similarities. Chuck Finnley Drakefield University Comparison and Contrast of Organic and Conventional Farming: An Overview of Differences and Similarities. Even though people believe organic food is safer, healthier, and environmentally friendly compared to conventional crops, there are few differences, and research demonstrates both methods provide the same nutritional value and both are exposed to similar pesticides. The practices used in both types of farming have led to products fewer differences than the public often believes. Much of what most consider to be common knowledge about the quality and safety of the two farming methods is false. The methods used in both types of farming often yield the same results. It is often believed that there are stark differences in the methods used to produce organic and conventional crops. Exploring the practices of both types of farming we discover that many safety concerns are equally valid for both methods of farming. The pesticides used in organic and conventional farming are derived from different sources, but both pose health risks. Organic farms are allowed to use pesticides. This is contrary to what many people believe about the practices of organic farming. When people hear organic they often think of pesticide-free farming. To be certified as organic in the United States farmers must follow a basic set of practices outlined...
