Have you looked into the animal abuses that take place regularly in places like the USA in factory farms? There is a reason they tend to have good security practices and an army of lobbyists. They need to ensure the undercover videos stop getting leaked of how they treat cows, chickens, pigs, etc... They also need the politicians in their back pocket to ensure no regulations can be passed/enforced so they can continue to squeeze out every penny of profit for their shareholders at the expense of the animals.

I liken it to how I see corruption in day to day life when visiting countries in south asia. Local bureaucrats and cops demand bribes regularly. In America, the bribery/corruption is only allowed at the highest levels (lobbying and the 2 tier justice system) so you don't see it daily. Therefore we think there is less corruption in America because its not in your face day to day.

Similarly, animal abuses in some of the places you mentioned may occur on the streets (very unfortunate). In places like America, they happen behind closed doors where the animals (slaves) are unseen until they show up in the supermarket.
