How to tell if bacon is bad
Check the expiry date on the bacon packet.
If the " use by " date has expired, then that bacon is unsafe to use. Always use bacon within seven days of purchase (" sell by ") or by the " use by " date listed by the manufacturer.

Options are:
*You can also safely thaw and cook the bacon within four months of freezing bacon. Take care not to confuse the " sell by " and " use by " dates.;
*The expiry date is on the packaging. If it is written before the expiry date, then the bacon is bad.;
*Furthermore, the date on the packet may indicate how the bacon was sliced prior to the expiry date. Bacon contains a significant amount of fat during cooking.;
*If the expiry date is frequently displayed under the " use by " date, then you probably need to start over. If the expiry date never shows on the packet, that means that the bacon has gone bad.;
The answer is:
You can also safely thaw and cook the bacon within four months of freezing bacon. Take care not to confuse the " sell by " and " use by " dates.
