FSAI chief executive Dr Pamela Byrne said that she was disappointed by the lack of vigilance by some owners in ensuring their food businesses were fully compliant with food safety legislation.
"We continue to find unacceptable levels of non-compliance with food safety legislation," she said.
"There are still some food business operators who are potentially putting their customers’ health at risk by not complying with their legal obligations for food safety and hygiene.
"There is absolutely no excuse for these negligent practices.
"Food businesses must recognise that the legal onus is on them to make sure that the food they serve is safe to eat. This requires ongoing compliance with food safety and hygiene standards."
