That generally depends on one thing: Notice. If it can be shown that the store had notice of the substance you fell on, then you may have a claim. Notice can be established in one of three ways. One, that the store created the substance you fell on, and failed to correct it in a timely manner. Two, that the store knew about the substance, and failed to correct it in a timely manner. Third, that the store should have known about the substance through reasonable inspection and maintenance, but failed to do that.
Therefore, the success of your slip and fall case against a Massachusetts supermarket will depend largely on the element of notice, and whether, and how strong, that element can be established.
