from The Tampa Tribune:
Investigation shows elevated levels of lead in grocery bags
Publix officials will revamp their lineup of re-usable grocery bags sold in their stores after a Tampa Tribune investigation found elevated levels of lead in material of some bags. Tribune tests showed certain bags from Winn-Dixie and Publix stores had levels of lead that concerned health officials. And some bags had enough lead that they could be considered hazardous waste if residents put them in their household trash. This follows a similar issue that led the Northern grocer Wegmans to voluntarily exchange thousands of their bags. Publix officials stress that their bags comply with current federal laws regarding lead content. But given the Tribune findings, and lower thresholds due next year, Publix is asking bag suppliers to find ways to make bags with less lead...over time lab experts note the bags wear down and paint can flake off, and eventually re-usable bags would accumulate in landfills, presenting another ecological issue.. ...


Worst of all the lead makes the bags a lot heavier!

from London Guardian:
McDonald's and PepsiCo to help write UK health policy
The Department of Health is putting the fast food companies McDonald's and KFC and processed food and drink manufacturers such as PepsiCo, Kellogg's, Unilever, Mars and Diageo at the heart of writing government policy on obesity, alcohol and diet-related disease, the Guardian has learned. In an overhaul of public health, said by campaign groups to be the equivalent of handing smoking policy over to the tobacco industry, health secretary Andrew Lansley has set up five "responsibility deal" networks with business, co-chaired by ministers, to come up with policies. Some of these are expected to be used in the public health white paper due in the next month. ...


I thought this sort of thing only happened in the good ol' USA.

from University of Toronto:
Dangerous chemicals in food wrappers likely migrating to humans
U of T scientists have found that chemicals used to line junk food wrappers and microwave popcorn bags are migrating into food and being ingested by people where they are contributing to chemical contamination observed in blood. Perfluorinated carboxylic acids or PFCAs are the breakdown products of chemicals used to make non-stick and water- and stain-repellant products ranging from kitchen pans to clothing to food packaging. PFCAs, the best known of which is perfluorooctanoic acid (PFOA), are found in humans all around the world. "We suspected that a major source of human PFCA exposure may be the consumption and metabolism of polyfluoroalkyl phosphate esters or PAPs," said Jessica D'eon, a graduate student in the Department of Chemistry. "PAPs are applied as greaseproofing agents to paper food contact packaging such as fast food wrappers and microwave popcorn bags."... "In this study we clearly demonstrate that the current use of PAPs in food contact applications does result in human exposure to PFCAs, including PFOA. We cannot tell whether PAPs are the sole source of human PFOA exposure or even the most important, but we can say unequivocally that PAPs are a source and the evidence from this study suggests this could be significant." ...


What a lot of PAP.

from CBC News:
Bisphenol A linked to sterility in roundworms
The controversial chemical bisphenol A can render roundworms sterile, kill their embryos, and damage their chromosomes, according to a new lab study. The findings are sure to re-ignite debate over the health safety of the chemical commonly known as BPA, which is widely used in such consumer products as hard plastic toys, bottles and food container linings. Geneticists at the Harvard Medical School found that in roundworms exposed to BPA, some DNA repair processes were impaired in the very cells that are essential for the formation of sperm and eggs. Exposure to the chemical also damaged chromosomal integrity and led to cell death, the authors found. While chromosomes in the control group of roundworms appeared normal, the chromosomes in the group exposed to BPA were frayed and fragmented. That led to embryo death and less fertile worms. ...


Don't you dare stick a roundworm into my square worldview.

from Environmental Health Perspectives:
Chemicals in cosmetics, moisturizers linked to DNA damage in human sperm.
One type of paraben preservative -- butyl paraben (BP) -- was linked to DNA damage in men's sperm, according to a study that compared the levels of this compound to several reproductive measures in men. DNA damage in sperm cells can have negative effects on men's reproductive potential. The findings indicate that the higher the BP levels, the more DNA damage the sperm had. The relationship was even stronger when BP and bisphenol-A (BPA) levels were considered together. This is the first study to look at the relationship between paraben levels in men and sperm health. A prior study found that the late stages of sperm production were affected in mice fed BP. The results warrant further investigation into effects of parabens on men's sperm health as well as their effects on female reproductive systems and pregnancy and birth measures, given that women typically have higher levels of parabens than men. Parabens are a group of antimicrobial chemicals often used to preserve cosmetics, pharmaceuticals and sometimes food. They are added to numerous personal care products -- including make-up, shaving gels, lotions and creams -- and some food and drinks. ...


That my shaving gel may make me less manly just flies in the face reason!
