Marrickville Pork Roll, which claims to have the best banh mi in Sydney, was fined a total of $1,760 for twice failing to comply with food standards in January.

The popular eatery, in its namesake suburb, has now violated health and safety regulations three times in the last five months.

On January 17, food inspectors found the shop failed to maintain accessible hand washing facilities for staff.

The NSW Food Authority said the company had already been fined for this offence in the past.

Only 10 days earlier, the owners were fined another $880 for failure to store potentially hazardous food under temperature control.

The company was fined for the same offence last August.

The hole-in-the-wall shop attracts loyal customers day and night, with people willing to line up in snaking queues for their famous rolls.

In May 2018, the company opened another store in Darling Square's Steam Mill Lane which has also attracted a number of hygiene penalties.

The store was handed a hefty fine last September for three breaches; failure to ensure hand washing facilities were not used for any other purpose, failure to supply single use towels near hand washing facilities and failure to store food so it is protected from potential contamination.

Together the fines came to a total of $1,320.

During the lunchtime peak, customers also queue in long lines at the Haymarket outpost.

The NSW Food Authority has the power to take legal action against food businesses where repeated breaches occur and where there is a high risk to public health and safety.
