Bacon has received mixed reviews from the public.
On one hand, bacon has received a positive reception by the public.
"Bacon Today" states that bacon has a very valuable amount of protein that is "valuable to maintaining our energy levels and a fully functioning, healthy body, with a minimum of those nasty, waist, thigh and butt expanding, fat building carbohydrates."
"Everything Tastes Better with Bacon", a book by Sara Perry, is a cookbook that compliments bacon's many uses in cooking.
On the other hand, as with most meat products, producers of bacon have received heavy criticism for how their pigs are treated.
Many petitions and protests have occurred trying to raise awareness and change how producers treat their pigs.
Many of these protests have turned out successful: for example, following NBC News's report of an undercover investigation of an abusive pig farm, Tyson Foods terminated their contract with the pig farm.
Similar to NBC's investigation, The Humane Society of the United States (HSUS) investigated Seaboard Foods, one of the pig breeding facilities that supply Walmart.
According to HSUS, the pigs were treated poorly and abused.
Walmart spokesperson Diana Gee said, ""As soon as we were made aware of the allegations, we immediately reached out to Seaboard to begin investigating the issue ...
Pending our review, we will take any action necessary.""
Petitions also exist that oppose poor treatment of pigs, many of which state that the current treatment of pigs in factories is cruel and unethical.
