About Harbor Fish Market

Harbor Fish Market is a historic, family-owned seafood market headquartered in Portland, Maine. Founded around 1890 and operating under its current name since 1966, the market is owned by the Alfiero family and runs two retail locations — one at 9 Custom House Wharf in Portland’s Old Port and a second at 246 US Route 1 in Scarborough, Maine. The market serves both retail customers and wholesale clients, selling fresh fish, lobsters, and a wide variety of seafood. Because the breach involved financial account and payment card data, customers who made purchases at Harbor Fish Market may be at risk of financial fraud.

What Should You Do?

If you received a notice from Harbor Fish Market or believe your financial account or payment card information may have been exposed, you should act promptly to protect yourself. Review your bank and credit card statements carefully for any unauthorized charges and report suspicious activity to your financial institution immediately. You can also place a fraud alert or credit freeze with the three major credit bureaus — Equifax, Experian, and TransUnion — to make it harder for someone to open new accounts in your name.
