Abstract

Food fraud is one of the risks in the supply chain globalization. A complex and long supply chain withdifferent locations, cultures, business ethics, policies and surveillance systems are the contributing factorsto food fraud. This study aims to identify food fraud vulnerability factors in milk powder producers. Itwas conducted in two companies which uses powder and liquid milk as the raw materials which istypical in Indonesian powdered milk industry. The study steps consist of respondents determination,data collection and analysis, formulating mitigation strategies. The respondents were company’s headof departments and a government officer of the National Agency for Drug and Food. Data collectionand analysis were carried out with the Safe Supply Affordable Food Everywhere (SSAFE) tool, whilemitigation strategies was formulated through Focus Group Discussion. The results show that vulnerabilityto food fraud rooted from the opportunity factor, namely the easiness and availability of technologyto commit fraud, motivational factor namely the level of corruption and regulatory differences thataffect prices, control measures factors due to lack of supervision, employee integrity tests and preventionguidelines. Internally improving control measures within the company and guideline prevention fromthe government were mitigation measures to be done.

Abstract

Bacillus cereus is known to have the ability to adhere and form biofilms on the surface of stainless steel that causes problems in the food industries. Bacterial biofilms generally can increase resistance to sanitizer treatment. This study aimed to evaluate the ability of peracetic acid-based commercial sanitizer to inactivate B. cereus biofilm on stainless steel (SS) surfaces. Biofilm of B. cereus ATCC 10876 was developed on SS surfaces and treated with 7 commercial peracetic acid-based sanitizers at their recommended dosages. Two sanitizers, i.e. B (peracetic acid and QAC) and F (peracetic acid and acidified water) showing the ability to inactivate B. cereus on solid media at concentration of 200, 400, and 800 ppm were further tested on biofilms with contact times of 1, 3, and 5 minutes. The 48 hours biofilms B. cereus contained 2.78-3.78 CFU/cm2. Both sanitizers B and F had significant effects in inactivating B. cereus biofilm. In general, sanitizer B could reduce more biofilm bacteria at any contact time than sanitizer F. Use of 200 ppm of sanitizer B or F 5 minutes could inactivate 3.04 log CFU/cm2 and 2.68 log CFU/cm2 biofilm, respectively. Exposure of B. cereus biofilm to peracetic acid-based sanitizer resulted in the damage of the extracellular matrix of the biofilms. This study showed that commercial sanitizers containing peracetic acid and quaternary ammonium compounds were effective in inactivating B. cereus biofilms.
