I'm an avid practitioner of the 5 second rule...depending on whether or not I see anything stuck to the food that hit the floor or if the dogs get to it first... :tongue2:

Our dog is pretty smart. If I drop something she will come stare at it for a couple seconds and if I don't grab it then she goes for it. It hasn't killed me yet I don't plan to change.

I'll take my chances on keeping the 5 second rule sacred in my house rather than read this:
ABSTRACT
Bacterial cross-contamination from surfaces to food can contribute to foodborne disease. The cross-contamination rate of Enterobacter aerogenes was evaluated on household surfaces using scenarios that differed by surface type, food type, contact time (<1, 5, 30 and 300 s), and inoculum matrix (tryptic soy broth or peptone buffer). The surfaces used were stainless steel, tile, wood and carpet. The food types were watermelon, bread, bread with butter and gummy candy. Surfaces (25 cm2) were spot inoculated with 1 ml of inoculum and allowed to dry for 5 h, yielding an approximate concentration of 107 CFU/surface. Foods (with 16 cm2 contact area) were dropped on the surfaces from a height of 12.5 cm and left to rest as appropriate. Post transfer surfaces and foods were placed in sterile filter bags and homogenized or massaged, diluted and plated on tryptic soy agar. The transfer rate was quantified as the log % transfer from the surface to the food. Contact time, food and surface type all had a highly significant effect (P<0.000001) on log % transfer of bacteria. The inoculum matrix (TSB or peptone buffer) also had a significant effect on transfer (P = 0.013), and most interaction terms were significant. More bacteria transferred to watermelon (∼0.2-97%) relative to other foods, while fewer bacteria transferred to gummy candy (∼0.1-62%). Transfer of bacteria to bread (∼0.02-94%) and bread with butter (∼0.02-82%) were similar, and transfer rates under a given set of condition were more variable compared with watermelon and gummy candy.

I eat so much dirty sawdust at work I don't really have a five second rule. If I drop something and it gets so coated I can't see it, the floor can have it.

Yup... Gotta be quicker than 5 seconds - Whenever I am in the kitchen, Chewy is on patrol and fully alert.

How else are you going to get your USRDA for dirt?

Same with the two rotten animals we have....

Now that is bad. When you have to bail out of the outhouse to throw up.

Having had occasion to witness what lurks in the blue 'waters' of your average construction site green-room - I can guarantee that 'going outside to throw up' is eminently preferable...

We have a dog and a cat as well. Both are chow hounds. Nothing dropped ever lasts five seconds.

One of my clients has a business which repairs sewage pumps. The women who works there said guys are so used to the poop covered pumps she sees the employees eating sandwiches and potato chips with their dirty hands while rebuilding them.

@Idaho_Cowboy
One must also take into account the INTENTIONAL drop.
