Hi Judith, thanks for the question.

You are probably correct: however, some sources this is just a bruising or the fruit in the later stages of ripening (blowing sand) which then become open to the disease. These spots can become larger sunken spots of Anthracnose.  

The safety of eating these tomatoes is mixed.  Some sources indicate you should not eat infected fruit, whereas other sources indicate that you can eat them by simply removing the infected area. Check out the following links for more information.
