• Physical hazards analysis in US meat and poultry recalls products  
  by Mohd Taufiq Mohd Khairi, Sallehuddin Ibrahim, Mohd Amri Md Yunus 
  Abstract: This study analyses the food recalls caused by physical hazards among meat and poultry products using dataset obtained from the US Department of Agriculture (USDA) Food Safety and Inspection Service (FSIS). The data was collected between 2014 and 2019. The global Chi-square test was used to investigate the association between topic categories. The chi-square per cell test also was utilised to enable a deeper analysis of the contingency table. Poultry products recorded the highest number of recalls with 39 cases, followed by beef and pork with 38 and 26 cases, respectively. Concerning foreign bodies, plastic fragments were the most detected objects with 42 cases, followed by metal and unknown objects with 29 and 11 cases, respectively. The ways on how to manage the physical hazards such as precautionary measures plan and detection technologies are also discussed in this paper.
  Keywords: Food recall; food safety; foreign object.
  
  
• Growth kinetics of coliform bacteria isolated from food  
  by Gizem Özlük Çilak, Hayriye Bahar, Ümmü Büşra Yavuz, Eda Nilsun Emin, Sinan Bostan, Hilal Selamoğlu Ata, Kadir Halkman 
  Abstract: It was aimed to obtain the growth kinetic parameters of food related coliform bacteria so that the industry can take action against not only to well-known Escherichia coli but also all. Isolates of Citrobacter freundii, Enterobacter aerogenes, Enterobacter cloacae, Escherichia coli and Klebsiella pneumoniae were obtained from food samples and pure cultures were inoculated to three different media (tryptic soy broth, lauryl sulphate tryptose broth and lactose broth) and incubated at two different temperatures (28°C and 37°C) for six hours. The kinetic factors for exponential phase of each bacterium in all media, at all temperature were determined. This study showed that coliform bacteria acts differently and have different preference of medium and temperature which may end up in masking by competitive flora, thus it is recommended to use at least two different media at two different temperatures in coliform analysis.
  Keywords: coliform; Escherichia coli; Klebsiella pneumoniae; Citrobacter freundii; Enterobacter aerogenes; Enterobacter cloacae; kinetic factors; specific growth rate; generation time.

• Behaviours of seafood consumption and risk perceptions in small island developing states, Mauritius following the MV Wakashio oil spill  
  by Devendra Appadoo, Dayawatee Goburdhun, Arvind Ruggoo 
  Abstract: The study aims at exploring seafood consumption pattern, risk perceptions and degree of concern regarding the safety of local seafoods before, during and five months after the MV Wakashio oil spill amongst a sample of 400 respondents including three sub-categories namely fishermen (n = 100), consumers in impacted zones (n = 150) and consumers in inland areas (n = 150) using a well-structured questionnaire during face to face interviews. There was a decline in local seafood consumption and an increase in imported seafood consumption from the pre-spill period to the spill and post-spill periods. This was more prevalent among respondents from the impacted zones than the inland respondents. The findings indicate that the oil spill had adverse impacts on Mauritian consumers.
  Keywords: behaviours; seafood consumption; risk perceptions; MV Wakashio oil spill; environmental pollution; seafood safety; seafood quality.

• Development and evaluation of coffee substitute from roselle (Hibiscus sabdariffa) seeds  
  by Abosede Oluwakemi Oduntan, Onaolapo Adeola Olatunji, David Olamide Rapheal, Oluwayemisi Martha Oni, Balikis Oluwakemi Mustapha, Rabiat Shola Ahmed, Titilope Modupe Fasuan, Adebisi. Omolola Akinrinola 
  Abstract: This study examined the potential of roselle seeds as a coffee substitute, examining the impact of roasting on their quality. Roselle seeds were roasted for 10 (RR10), 20 (RR20) and 30 (RR30) minutes, while unprocessed seeds served as control. The samples’ bioactive and sensory properties were analysed using standard experimental procedures. The flavonoid, total phenol, tannin and saponin ranges were 7.26-54.56 mg/g, 1.44-10.52 mg/ml, 0.047-0.36 mg/ml and 0.03-0.65 mg/ml, respectively. The antinutrients were within permissible limits. DPPH for RR10 was 28.38% and increased by 22.61% and 106.91% in RR20 and RR30, respectively. RR30 had the highest flavour, taste, body, balance, and overall acceptability. RR20 had the highest acidity. Commercial coffee was the most preferred in terms of colour and aroma, closely rivalled by RR30. RR30 is therefore the best viable roselle alternative to commercial coffee, especially for people with low caffeine tolerance.
  Keywords: roselle seeds; coffee substitute; bioactive composition; antinutrients; roasting.
