Most Worcestershire sauces as well as some barbecue and steak sauces contain anchovies and state so in their ingredient listings. According to most Poskim, if the amount of anchovies in these sauces is at a ratio of 1/60 or less, they may be used with meat. Some Poskim, however, are more stringent. Consult your Rav.
Reliably certified sauces that do NOT state “FISH” on the label next to the Kashrus symbol do NOT contain more than 1/60 fish. Sauces that DO contain more than 1/60 fish will state “FISH” next to their Kashrus symbol. Contact the certifying Kashrus agency to ascertain the fish level in a FISH marked sauce.
The following are the fish levels in some common sauces that are marked “O/U FISH”:
More Than 1/50 – Lea & Perrins Worcestershire Sauce (may NOT be used with meat)
NOT more than 1/60:
