Jobs indirectly related to the meat business According to the Vanijja Sutta on Right Livelihood:


  "Monks, a lay follower should not engage in five types of business.
  Which five? Business in weapons, business in human beings, business
  in meat, business in intoxicants, and business in poison.


The first precept forbids taking of a life.

The ability to freeze, store, transport and sell meat later was not possible in the time of the Buddha.

Questions:


Is it ok for someone observing the first precept and Right Livelihood, to be a frozen meat retailer, supplier or importer selling frozen meat sourced from elsewhere (but is not involved with the actual farming and slaughter of animals)?
Is it ok for someone observing the first precept and Right Livelihood, to work as a cashier or general worker in a supermarket or hypermarket (e.g. Tesco, Target or Aldi) that sells many things including frozen meat?
Is it ok for someone observing the first precept and Right Livelihood, to work as an employee in a logistics company (like FedEx) that stores and transports all types of products including frozen meat?
Is it ok for someone observing the first precept and Right Livelihood, to work as a chef or waiter in a restaurant that serves meat dishes, using only frozen meat (no live animals)?
The reason the Buddha suggested we abstain from certain things is not because of the morality of the actions themselves, but because of the effect these actions have on our minds.

The fact that you are even asking this question illustrates there is some sort of mental suffering/inner conflict that has arrisen. This is the suffering we are attempting to avoid by abstaining from specific actions. This is what the Buddha warned us of. 

You are always free to do whatever you wish! I would just suggest you not do something that brings you suffering.
