Within reason, probably yes. I'm convinced that 'sell by' and 'use by' dates are deliberately understated to make consumers throw the items away before they've gone bad and buy more.
Before their introduction, people used to trust to their senses (sight, smell and taste) which had stood them and their ancestors in good stead for thousands of years, to determine whether something was still all right to eat or drink.. In the case of milk and dairy products, they will probably go off quicker than other foodstuffs, but if the milk looks and smells OK then it probably is. If it's for a baby or child though, it's best not to take any chances.
