Food-borne diseases cause 48 million illnesses, 128,000 hospitalizations and 3,000 deaths each year in the United States, according to the CDC. In the past six years, salmonella-contaminated peanut butter caused 1,139 infections in 44 states, while more than 90 pounds of e. coli-tainted foods were recalled during a two-week period in 2013. As many as 73% of Americans reported that they are concerned that food may not be safe to eat, according to a 2010 Harris Poll. Luckily, help is on the horizon, in the form of tiny little bugs. Yes, you read that right: bugs.
