We reported a few weeks back about how Yoplait was going growth-hormone free. Well now Dannon's following suit, reports Civil Eats. Dannon, which controls around one third of the country's dairy market, cites consumer demand as the reason behind the change. The company says it will go rbGH (recombinant bovine growth hormone)-free by the end of the year.

There are various health and animal rights issues surrounding the use of rbGH on dairy cows. The hormones have been linked to increased rates of infections in cattle, necessitating greater antibiotic use. And some studies have shown that rbGH raises levels of a hormone in cow's milk; higher than normal levels of IGF-1 in humans may raise the risk of breast cancer. Others say no significant difference has been shown between milk from rBST-treated and milk from non-rBST-treated cows.

Although many consumers are concerned with the standard of living of the cows, one of the primary reasons that people buy organic milk is because they are concerned about drinking milk from cows that have been treated with hormones, specifically the growth hormone rBST. The hormone has been in use since 1993 and estimates say that about 22% of cows are regularly treated with it. Only about 3% of the milk market is covered by organic milk and, due to demand and the higher operating costs of organic farms, organic milk can cost consumers twice as much as conventional milk.

For both consumers and producers, there is a middle ground: hormone free milk. Dairies do not have to meet the standards for organic milk, which is good from a time/cost perspective, but they can charge more for the hormone-free milk than for conventional. The non-rBST milk is usually priced right between conventional and organic, so shoppers can save and still get milk they feel comfortable drinking.

British supermarket chains, such as Asda, Tesco, Morrisons, Sainsbury's and Waitrose, are rethinking their pork supplier. The Polish pig farms that produced much of the supermarket pork products have been condemned for "'appalling' animal welfare practices."

The farms in question are in Poland and have been run by Animex, a subsidiary of the American company Smithfield Foods, since 2002. An undercover investigation revealed industrial factory farms, conditions where hundreds of pigs were crammed into light-less barns with dead companions rotting underfoot. The investigation also found that "powerful cocktails of drugs," including a cocktail of antibiotics that is banned or considered to be a growth-promoter in other countries. One such drug is Tylbian 20%, a form of the growth promoting drug Tylosin, which was banned by the European Union in 1999. Local residents showed investigators large open-air cesspits of pig waste and farm detritus that included syringes and needles.

Waitrose has already pulled the products supplied by this producer. No wrong-doing has been shown on the part of Smithfield Foods and a Smithfield representative denied knowledge of such conditions, assuring the public that it would investigate thoroughly.
