This article is somewhat odd in the sense that of course, bacteria are everywhere, and yet not all bacteria are bad, and there are bad things in addition to bacteria. As Dr. Dean Edell used to say, "about 90% of the disease pathway is fecal-oral". After spending a career in Civil Engineering, including water/wastewater treatment and raising chickens/milking cows, I'd say these are the big ones:

1) Properly disposing of garbage, for fear of flies, rodents, roaches. Keeping surfaces free of cobwebs (although spiders are not altogether bad, can be disease vector or fire hazard ).

2) Proper food prep, especially around uncooked poultry and beef products (often w salmonella and e coli contamination, as chickens and cows are sometimes covered in sh*t). This means cooking properly, cleaning/sterilizing the cutting board, etc.

3) Separating potable water from human waste. This is actually getting harder all the time, crypto and giardia are trying to sneak in (fecal-oral pathway again, your article is about bacteria, but protozoans actually an issue). Around home, proper disposal of human and animal feces a must (ie cat feces contain toxoplasma).

4) I'm all for "organic" but as Michael Pollan would tell you, the label is overly broad, sometimes vegetables grown too close to cattle or poultry or even fertilized w not properly processed "manure" (compost needs to cook to destroy pathogens). I wonder if "organic" veggies may be close to needing irradiation or light disinfection. We used to drink raw milk, but I made darned sure it was fresh and tested free of listeria, e coli, salmonella, etc.

5) For me, I don't worry about my shower head, washing machine, or dishwasher, but I'm careful w my food prep, garbage and animal waste.

Thanks for the article.
