Consumer awareness and food safety involve with a wide area of public interest about food safety issues. In this study, 16 (sixteen) slaughterhouses and 73 (seventy three) meat shops were selected from 18 markets in Khulna municipal area to collect data through a well structured questionnaire. The information was collected to evaluate the way of fraudulent activity of sellers related about meat. Results have shown a significant percentage of illegal practices done in slaughterhouses in Khulna city area. The slaughter houses are mostly found un-hygienic and certain chemicals also get mixed with meat causing danger to consumers. It is also observed that 5 slaughter-houses among 16 are involved in this type of illegal activity. An integrated and systems-based approach to food protection must be encompassed in both food safety and food defense which are imperative for ensuring the integrity of our food supply.
