The largest study to date on poultry workers found a significantly increased risk of dying from penile cancer, thought to be due to exposure to oncogenic (cancer-causing) chicken viruses, which raise consumer concerns as well.

Last year, I presented the study on poultry slaughterplant workers, where they were found to have excess cancers of the mouth, nasal cavities, throat, tonsils, inner ear cancer, sinus cancer, esophageal, rectal, liver, leukemia etc. thought to be because they are exposed to cancer causing viruses present in poultry and poultry products, and worse that they may be transmitted to anyone in the general population handling or eating inadequately cooked chicken. It’s not clear how you’re supposed to not handle raw chicken yet somehow still levitate it into the oven.
The study was replicated recently in the largest such investigation to date, more than 20,000 workers in poultry slaughtering and packing plants. They found the same thing confirming the findings of three other studies to date that workers in poultry slaughtering and processing plants have increased risk of dying from certain cancers. New findings in this study were increased risk of death from cancers of the cervix and penis.
Excess cancer of the penis in all males, with a standardized mortality ratio more than 8-fold higher.

The previous slaughterhouse worker study I refer to is here: Wart Cancer Viruses In Food. There was also a study suggesting a relationship between cervical cancer and the viruses in meat (Pets & Human Lymphoma), but this is the first time I've seen penile cancer studied in this context. If there are so many viruses in chickens, don't they get into the eggs? That's tomorrow's video-of-the-day! See the previous two days' videos, Chicken Dioxins, Viruses, or Antibiotics and EPIC Findings on Lymphoma for a discussion of meat lymphoma risk. (Not to mention the hundreds of other videos on more than a thousand subjects).
