Ohio's largest television news station at the time aired the footage, promoting the segment as "The Video the Egg Industry Doesn't Want You to See".

[3] In 2008, animal rights advocates organized a grassroots campaign across California to pass Proposition 2, a state ballot initiative requiring that egg-laying hens, pregnant pigs, and calves raised for veal be given enough room to lie down, stand up, fully extend their limbs, and turn around.

MFA released investigative footage from inside two of California's largest egg farms, Gemperle Enterprises and Norco Ranch, just two weeks before the vote.

A year later, MFA investigators in Maine uncovered workers and managers at an egg factory farm killing birds by grabbing them by the neck and swinging them in the air.

The facility owner pled guilty to 10 counts of animal cruelty and agreed to pay more than $130,000 in fines and restitution, the largest financial penalty ever levied against a U.S. factory farm.

MFA's first exposé of the Canadian pork industry prompted the country's eight largest grocers to phase gestation crates out of their supply chains.

[14] Following the exposé and public outcry, McDonald's announced a policy to eliminate cages for hens from its North American supplier farms.

Media outlets CNN,[17] the Associated Press,[18] NBC,[19] and USA Today reported on the investigations, which revealed workers violently stomping on turkeys, dragging them by their wings and necks, slamming them into transport crates, and leaving many to suffer from untreated injuries and infections.

[22] After the video received widespread media attention, Nestlé, the largest food company in the world, met with MFA and implemented a far-reaching animal welfare policy.

[30] Following MFA's exposés and campaigns, top U.S. grocers Publix,[31] Kroger,[32] Albertsons,[33] and SUPERVALU,[34] along with the Retail Council of Canada,[35] also pledged to ban intensive confinement of hens from their egg supply chains.

[37] In June 2016, Perdue, one of the largest chicken producers in the world, announced a precedent-setting commitment to improving animal welfare after MFA investigated two contract farms in the U.S. supplying the company.

[39] In an online petition, Eugenio wrote, "I watched the video in horror as animals were tied up, shocked for no reason, brutally and repeatedly bludgeoned with sledgehammers, and then stabbed in the back of the head.

"[citation needed] Back in the U.S., MFA was also part of a coalition of organizations that worked to pass the Prevention of Farm Animal Cruelty Act in Massachusetts.

[43] The measure, passed in 2016, outlaws some of the cruelest farming practices and bans the sale of eggs, pork, and veal from animals raised in intensive confinement.

[44] After the 2016 investigations, MFA worked with members of Mexico's congress to introduce federal legislation that would end the worst slaughter methods shown in the undercover video.

[52] After MFA campaigns or discussions with MFA, dozens of other major brands in the U.S., Canada, Mexico, and Brazil,  including Burger King,[53] General Mills,[54] Jack in the Box,[55] Pollo Pepe, Les Croissants, Loz Car, Grupo Alimentos Vitales de México, Habib's, and Grupo Halipar (Brazil) pledged to change how they treat animals.

[60] A 2020 investigation focusing on the live export industry in Brazil revealed animals being confined in large ships in cramped conditions for weeks on end, often lying in and covered in their own feces.

[67] In 2019, Leah Garcés founded Transfarmation to support farmers to transition from Concentrated Animal Feeding Operationss to plant-focused farms.
