Hazard Analysis and Risk-Based Preventive Controls (HARPC): Current Food Safety and Quality Standards for Complementary Foods

The application of systematic accident analysis tools to investigate food safety incidents

Effective food safety (FS) management relies on the understanding of the factors that contribute to FS incidents (FSIs) and the means for their mitigation and control. This review aims to explore the application of systematic accident analysis tools to both design FS management systems (FSMSs) as well as to investigate FSI to identify contributive and causative factors associated with FSI and the means for their elimination or control. The study has compared and contrasted the diverse characteristics of linear, epidemiological, and systematic accident analysis tools and hazard analysis critical control point (HACCP) and the types and depth of qualitative and quantitative analysis they promote. Systematic accident analysis tools, such as the Accident Map Model, the Functional Resonance Accident Model, or the Systems Theoretical Accident Model and Processes, are flexible systematic approaches to analyzing FSI within a socio-technical food system which is complex and continually evolving. They can be applied at organizational, supply chain, or wider food system levels. As with the application of HACCP principles, the process is time-consuming and requires skilled users to achieve the level of systematic analysis required to ensure effective validation and verification of FSMS and revalidation and reverification following an FSI. Effective revalidation and reverification are essential to prevent recurrent FSI and to inform new practices and processes for emergent FS concerns and the means for their control.

Investigation and assessment of natural radioactivity in commercial animal feeds in Texas

Commercial animal feed in Texas was characterized by determining natural gamma emitters including 40K,137Cs, and Uranium (235U and 238U) and Thorium (232Th) series to obtain basic radioactivity values. The measured activity concentration of natural radionuclides in animal feed was low enough for safe consumption by animal and largely depended on the type of animal feed.40K was the predominant radionuclide showing the highest activity concentration in animal feed. The radioactivity concentration of 214 Bi and 214Pb in 238U decay series was 1.39 and 1.33 Bq/kg in corn, respectively, lower than in other animal feed types. On the other hand, the vitamin/mineral mix samples showed higher concentrations of 214 Bi (9.04 Bq/kg) and 214Pb (10.19 Bq/kg). Beef cattle feed, poultry feed, and vitamin/mineral mix exhibited higher activity concentration of 228Ac and 212Pb in 232Th decay series. Gamma radionuclides appeared to be highly and significantly correlated within each decay series. 235U was present at low levels in all feed samples while the anthropogenic radionuclide of 137Cs was not detected irrespective of the type of animal feed. This study highlights an importance of establishing a current baseline of radioactivity concentration in animal feed in Texas in which the largest animal feed consumption in the US exists.

Practice and Progress: Updates on Outbreaks, Advances in Research, and Processing Technologies for Low-moisture Food Safety

Large, renowned outbreaks associated with low-moisture foods (LMFs) bring to light some of the potential, inherent risks that accompany foods with long shelf lives if pathogen contamination occurs. Subsequently, in 2013, Beuchat et al. (2013) noted the increased concern regarding these foods, specifically noting examples of persistence and resistance of pathogens in low-water activity foods (LWAFs), prevalence of pathogens in LWAF processing environments, and sources of and preventive measures for contamination of LWAFs. For the last decade, the body of knowledge related to LMF safety has exponentially expanded. This growing field and interest in LMF safety have led researchers to delve into survival and persistence studies, revealing that some foodborne pathogens can survive in LWAFs for months to years. Research has also uncovered many complications of working with foodborne pathogens in desiccated states, such as inoculation methods and molecular mechanisms that can impact pathogen survival and persistence. Moreover, outbreaks, recalls, and developments in LMF safety research have created a cascading feedback loop of pushing the field forward, which has also led to increased attention on how industry can improve LMF safety and raise safety standards. Scientists across academia, government agencies, and industry have partnered to develop and evaluate innovate thermal and nonthermal technologies to use on LMFs, which are described in the presented review. The objective of this review was to describe aspects of the extensive progress made by researchers and industry members in LMF safety, including lessons-learned about outbreaks and recalls, expansion of knowledge base about pathogens that contaminate LMFs, and mitigation strategies currently employed or in development to reduce food safety risks associated with LMFs.

Assessment of Breastfeeding, Weaning, and Complementary Feeding Practices Among Women Attending a Tertiary Care Teaching Hospital in South India

Introduction

Infants depend exclusively on mothers’ milk for nutrition in their early months of life. However, some infants are given cow/buffalo milk during insufficiency. After six months, the children are supplemented with complementary food, including solid food, to meet the nutritional requirements of a growing infant, a process known as weaning. Therefore, it is important for mothers to have a clear understanding of the nature of food, and the nutritional requirements of the children. This study aimed to understand the knowledge, awareness, and practice of breastfeeding, weaning, and complementary feeding among women.

Methods

A cross-sectional questionnaire-based observational study was carried out between May and June 2021. The study included 150 women attending the outpatient department of pediatrics attached to Mahavir Institute of Medical Sciences (MIMS), Vikarabad, Telangana, India. After taking the informed consent, the researcher filled out a pre-validated questionnaire based on the subjects' responses. The data regarding socio-demographic details and information regarding knowledge, timing, practices of weaning, knowledge of nutritional requirements, and child feeding practices were collected as a pre-test. An educational briefing of the essentials of child feeding practices, weaning, and dietary requirements was undertaken using chalk and board and audio-visual aids, among others. In the post-test, the knowledge of mothers regarding weaning practices, the importance of weaning, and understanding of the nutritional requirements and their inclusion in a child’s diet was assessed. The quantitative data were represented as percentages. The Chi-square test was applied to find out the statistical significance of the results obtained from the study.

Results

Of the 150 women who participated in the study, the majority belonged to the age group of 18-23 years (66.7%). Most women were illiterate (34%) and only 12% were graduates. More than 70% of the participants belonged to the middle and lower middle class. The majority of participants (96.7%) had carried out exclusive breastfeeding for the first six months, and 63.35% of mothers had initiated weaning their child between the age of 6-12 months. Only 37.4% of mothers started breastfeeding within hours after the delivery. A combination of all foods (36%), rice/wheat (29%), processed food (18.8%), fruits and vegetables (9.2%), and pulses (6.7%) were chosen for weaning. Many felt that eggs and meat supplementation can be done between 12-18 months.

Conclusion

The knowledge of breastfeeding and best practices of weaning and complementary feeding habits significantly affects the child’s growth and overall health. The women in this study had a moderate level of understanding regarding the aspects of breastfeeding, weaning practices, and complementary dietary requirements during weaning.
